I ran a 44km event in these and loved it. I also have boith the Alphafly 2, Vaporfly 2 and Vaporfly 3. I enjoy all of them but the best thing about the Boston 12s is that I just yanmk the laces nice and tight and they're always super comfortable. I find with the Nikes, I have to get the lace tightness just right for them to be secure but not give me a cramp 10km in. The Bostons just never worry me about that. If I was running a 5km as fast as possible, I'd take the Vaporfly 3s but the Bostons are going to be my next marathon shoe.
Got this shoe 2 weeks ago, my favorite shoe by far. really surprised by how comfortable/stable it is and how fast to it feels. it does easy paces well and picks up when you need it to.
Love love these Boston 12’s after the last 2 iterations, brilliant for high tempo runs and slow easy runs,perfectly said Nick about the difference between the 2 foams being less stark which makes for a smoother transition , it is such a major improvement even more than I expected , and relatively cheap with a promo code,so I had to get the green and pale blue colourway as I couldn’t decide 😂
Got the Boston 12 to replace the Boston 11 that I just couldn't get to work for me and I love it. It just may be my favorite daily trainer now although I still love the Deviate Nitro 2. I also have the Speed 3, Novablast 3, Hoka 5, Rebel v3, and Velocity Nitro 2 and they are all good with their unique strengths and rides but I find the Boston 12 the most satisfying, mainly due to the feel and ride underfoot. And, yes, as Nick says, the Boston 12 is fast and pushes you to run fast and do some demanding workouts. It really does have that race supershoe feel and ride. Like all Adizero shoes, the upper and tongue aren't the most inviting and comfortable and need a decent amount of lace fiddling but, once you dial it in, it becomes very comfortable as you run and don't even notice the upper. Adizero shoes aren't known for being plush and accommodating, but that's just how they are to emphasize speed and nimbleness. If you already have other Adizero shoes like the Prime X Strung, Adios Pro 3, Takumi Sen, and Adios like I do, then the Boston 12 will fit in very nicely. It's a fast daily trainer and very versatile although it's not the best for easy/slow paces. It's great for medium-to-fast paces - tempo runs, threshold runs, intervals, marathon-pace long runs, etc. Very happy with the Boston 12. I'm not even considering any other shoes in the so-called "super trainer" category. For me, Lightstrike Pro provides the best balance between propulsion/responsiveness and comfort/protection. It's not too firm and it's not too soft. For me, it's in that "goldilocks" zone that provides the most fun in my runs. The Boston 12 not only continues that tradition but builds upon it and makes it even better. The Lightstrike 2.0 also feels a lot better than v1 as well. This is just a great all-round running shoe.
@@RWG0914 Haven't tried the SL. My understanding is that it's pretty firm/stiff feeling. Some people like that though. I prefer something more balanced - not soft but not firm either, which the Boston 12 provides.
Hoping you still use UA-cam here but have a quick question 😂 Will these be suitable for a pace between 3:50 to 4:20 for intervals / threshold? I have the TS9’s that I love but they beat my legs up if I use them twice a week. Shoe reviewers rarely advertise their pace ranges lol
@@DPS93 Hey, still here checking up on new shoe tube reviews!😂 Yes, the Boston 12 can easily handle those paces and even all-out sprints at sub-3:00/km paces. Elites train in the Boston 12 so you can imagine how fast they are going. I have the TS9 as well and I agree they can beat up your legs if used more than once per week. The Boston 12 is very versatile. Its' noticeably heavier than the TS9, of course, but you can also use it for long tempo runs and some easy paces although it wants you to go fast. Hope this helps!
Got it last week, did 22k half easy pacey and half tempo run with it today and I was impressed. Really nice feel at slow run and felt light on tempo, really a great training shoes for the pro 3 I would say 👍
This video is so true that I wish the other shoe reviewers would watch. The super trainer class that is being peddled out there are just sod daily shoes. The Boston 12 is the only new super shoe minus the endorphin speed 3 superblast and dv2. The sc trainers of the world are just more built up triumph 21’s or magnify nitro 2’s. They don’t excel where the Boston 12 can.
Seems like the most recent Adidas releases Boston 12 & Adios 8) have really increased their arch support. One of my feet is a bit flatter than the other and can feel that extra arch support digging into it, giving me pretty significant pain after even a bit of running. No issues with previous releases such as the AP3 or Adios 7.
In the end, I loved my Boston 11 besides the fact it was a bit clunky in the first 50km or so and not the fastest daily trainers. But this performance shoe has been lasting a very long time to me so far (~350km ran) . But ,I want to try different plated shoes, and I'm curious about this Magic Speed 3. Anyways, in the end, having both the Boston 12 and Magic Speed 3 would be a dream come true in terms of fun for me ! Great video review !
Don't slow your speech Nick!....It's your natural rhythm!, Never missed what you're saying due to speed :) and cram lots of relevant information into limited time...spot on!
I just purchase this after using only Nike and Hoka over the last two years, at the last Maraton in Vaporfly 2 i ripped a gluteus medius because is so instable, so i hope this is more stable withc is seems i only run 17 kin this but seems fine my oly problem was that i use different muscles i need to adapt to this brand, lot of pain in the shin and from thies :)
Ran in this and I got to say. I surprisingly like it so far. The runing experience wasn't impressive at first, coulple of reviewers mentioned they need to go through break in to soften up a bit. But honestly first run, I kinda like the firmness. The bounce is slightly tuned down compared to my endorphin speed 3 but I reckon it would match up eventually after break in. Maybe a little boring, flat and firm but overall a fun cruising experience. I am now very excited to look forward to it after the break in miles.
Nice review Nick. Would these make a good marathon shoe for a “steady race” (as opposed to racing a marathon for PB!?). Looking forward to the Superblast review and comparisons for the same purpose!
I have both and to me they are really two different shoes with the Superblast having much more cushioning. If I’m only choosing one, I’d take the Suberblast all day
@@andrewstearns9276but asics reslly need to improve on the aesthetic department. Superblast looks just like Novablast 3 with different colorway. I know aesthetic is probably the least important /priority but its enough to put many on hold before dropping such hefty money and the competitor around easily offers carbon plate/rod system in betwen the midsole sandwich. Perhaps, dropping the price a lil bit to make it more competitive is much welcomed.
I'm currently deliberating between these and the ASICS Superblast. I fear the stripped down heel cup on the Boston 12s won't work for me though, and the Superblasts have a fairly traditional looking design.
I love the midsole and ride, but I can't get the fit right for this shoe. Anyone else having this problem? I usually take a US 7.5/EU 40.5. The 7.5 in this shoe feels good in the heel but I can't get a lock-down in the mid foot. My foot is literally sliding when I corner. I have tried to size down, but that feels small in the mid foot.
Have purchased several runners based Run Testers reviews, Including the Boston 12. I’m of the opinion the Puma Velocity Nitro 2 is as good as Boston 12. What is your opinion? Puma is stepping up their game and other shoe manufacturers should pay close attention.
My takumi sen 8s I struggle with the lacing. If I runners lock I get pain on the top of the foot. If I don’t the fit feels a bit saggy. Looks like the lacing could be similar here. Thanks for the review.
I just got mine about 5 days ago and love them. I came from the Adios Pro 7's. Ran 13.5 miles. Set a new PR on a 5k, all great. Laces took a bit to get the fit right, but now it's great.
Thanks for the review - curious to hear your thoughts on running a marathon in the speed 3's. I love them , I do most of my training in them - they fit me perfectly and feel great. I ran my firsr marathon in Feb in the E Pro 3 and got numb toes. I am enjoing the Adidas pro 3 but I get a bit of lace bite. I am running NY in Nov and thinking of running in my speed 3's despite trying a bunch of carbon plates shoes.- Thanks
Hi Nick, thanks for this review. The fit of the Speed 3 did not work, and I suspect the deviate nitro 2 to be a little bit too stiff and causing a small injury above my ankle. As I fell in love with the Takumis, I am considering these Boston for daily training and speed work and long runs and the adios pro 3 for eventually racing, but also long runs when the volume will be high. Your opinion helps a lot, I think I'll give them a try and compare with the Puma.
Recently bought a pair of the 11s prior to the launch of the 12. They're unwearable. Felt great for the first run but on the second it was immediately obvious that the sides of my big toes rubbed the inside of the shoe on both sides (I'd even gone half a size up) and length wasn't an issue. The main problem though was the heel counter, it's just awful and the stitching created a pressure point which made blisters inevitable. Please correct me if I'm wrong, but from what I can see, that doesn't look like it's been addressed in the 12.
Comparable to the Novablast 4 & Endorphin Speed 4?? My son is looking for a different pair to switch out his weekly runs and he loves his novblast 4s. Any suggestions?
Umm maybe the Boston 12 is a good example of a shoe that does not scale that well for those with larger feet. My UK 13.5 is about 340g and so a good 60g more than the Speed 3. OK it is lighter than the Boston 11 but still feels clunky and the 11 actually fitted me better as found the 12 quite voluminous up front but I do have relatively very narrow feet. For faster work I would take, from adidas alone, the Adios 8, Takumi Sen 9 or Adios Pro 3 everytime over these and all of them are "lightweight" even in my size and I find them fine for slower paces or going for longer runs. Did any of the other Run Testers try this one? Nick always has good insight but equally his paces are way faster than an average runner. In general "super trainers" largely for the weight reasons I alluded to seem a miss for me and anyway Superblast not even offered in my size. I tend to use the carbon racers like the Rocket X2 or Adios Pro 3 I don't like enough to race in but are good for uptempo runs as I don't have the huge weight penalty the lower tier shoes have in my size.
I have an underpronation on one side, and am looking for an alternative to the invincible 3 im currenlty using (which are great, but a bit boring), how are these shoes for stability? as the INV 3 are very good.
Boston 12 or Endorphin pro 3 👀 I honestly prefer training in Pros over the Speed. Speed to me have been bottoming out because I’m more over a power runner.
I want a do-all super trainer for everything except race day. 5k -1/2 distance , easy runs , tempo and intervals. Should i get this or the saucony pro 3? I can buy 2 of these for the price of 1 saucony.
What is overal stability? Can this be succesfully used for light over pronators? I'm aware that this is not stability shoe, but I sucessfuly use trail shoes that are just stable (Nike Pegasus Trail 4)) in my ratotaion with Brooks Adrenaline.
I find the Speed 3 mushy in a long run. Boston 12 stays fresh. Alone Speed 3 unstable at slow pace and Boston 12 very stable at any pace. Puma Deviate Nitro 2 fastest and upper more comfortable but again Puma Deviate Nitro 2 hates the slow paces and Boston 12 stable at all paces but Boston 12 feel bottom heavy at slow (recovery) pace.
Love the channel and your reviews! I'm hearing great things these at the moment! I'm looking for a shoe to train for and, ultimately, run London marathon in (around 4 to 4.5hrs) I've been running in stability shoes for years (adrenalines / guides / NB860) but I've recently started using stable neutral shoes like Hoka Mach 5's and just did a fast 10k race in Endorphin Pro 3's with absolutely no stability issues. Have you got any suggestions for shoes I could look at for the marathon? Many thanks.
Hmm interesting one! Elite 2 is lighter, faster for reps. less stable and cushy for the kind of relaxed long run I did today, but probably a fair bit of overlap there! Boston cheaper of course, and would expect longer lasting
Thanks. But I have no idea why any runner would use a shoe positioned as a daily trainer as a track shoe? Addidas has a few options for tempo shoes. Otherwise, the rest of your review makes sense.
Versatility is always a good thing! It’s great to have a shoe you can use for a bit of everything, especially if you don’t want a big shoe rotation. As someone who’s mainly a marathoner I also like a fairly cushioned shoe even for track since I rarely do all out short reps, so if I don’t use a carbon racer I tend to use shoes like Boston 12 or Endorphin Speed 3 rather than flats/spikes
Do any of the run testers have issues with Achilles pain? Trying to find a shoe that will get me through longer runs that will keep me pain free (puma velocity 2 has done the trick for daily training/shorter runs)
Hey Nick nice review.. I tried the shoes in store and I found that the lateral side of the heel was not level with the medial side (lateral side was not touching the ground), making it I guess not very stable at the heel.. Is it safe for a heel striker? All my shoes have significant wear on those lateral heel sides.. thanks
Only got 16 miles on mine so far so. But I do think they hit a spot the saucony speed 3 was missing. Upper isn't as soft or comfortable as the speed 3 but it's noticeable but doesn't seem to cause issues so far. I've always heard the adidas foam needs to break so will see what difference that makes when it happens.
Injury risk- The upper and laces on the Boston 12 are terrible. It's fine for shorter distances, but over longer runs or hills it causes heaps of pressure on the metatarsal & tarsal area of the feet. Disappointing as I'll need to ditch mine since it caused an injury. The lower is actually excellent.
I'm trying to hold off buying any more shoes and you're not helping Nick! Quick question, I can get Adios Pro 3 for £157 and Prime Ex Strung for £167 from SportsShoes (before 10% club discount), would either of those be a better option than the Boston 12 at those prices?
A question for you. You guys refer to shoes as being ‘true to size’ does this mean you classify them as being a like for like e.g I’d buy them in a size 8 if I measure a size 8 normally or does it mean you true to size for the say half size you would add on normally? I’m a bit confused as I have just bought some triumphs in my normal dress shoe size as Saucony website puts this as at least 5mm longer than this size would normally be in a dress shoe…
For me it means true to the size you usually take in running shoes and particularly from that brand as in UK sizes especially some brands numbering is different. For instance in UK sizes adidas, Hoka and New Balance is 0.5 UK size more than the same length shoe in Nike, Saucony, Brooks & Puma.
I must be the only person who really didn’t like the endorphin speed 3. They’ve given me consistent heel blisters and speed sessions in them are very hard on my forefoot (really bad blisters too). Not only this but the branding and logos literally started peeling off after my first run. That was my experience anyway 🤷♂️ doesn’t seem to match up with the constant praise I see that shoe getting
Takumi Sen is lighter and all-out faster. Less stable and I wouldn’t cruise a long run in them like I did the Boston today. Takumi a pure racer and session shoe for me, and best up to half distance, Boston can go longer
Super trainers are a hard sell for me at their list price… you can find the New Balance SC elite v3, the Adios Pro 3, and the Vaporfly 2 for about the same price (or even a little less) right now. I’d rather buy any of those than a full price super trainer.
Did my first run today in Boston 12... Great shoe.. Only improvement for me would be a bit more padded tongue which would help get the shoe on... It's a bit floppy and basically the same as the Takumi Sen 8. For a more daily trainer it should be a bit easier to get on and off. Lacing system is a good idea... Very easy to cinch down. The ride is top as is midsole comfort. Outsole is good as usual.
I’ve historically used Pegasus and spent a few weeks in a new balance prism which felt great just a little too firm. Going back to Pegasus I’m finding my legs ache and soleus is sore too. Is the Boston 12 a decent alternative to pegs?
Great review Nick. I’m looking at ordering a pair of these last pair I had was the Boston 9 but I had to half size up in them would you say the same with the 12 or so they run slightly bigger.
The Boston 12 could be a quite nice running shoe. But it's not (at least for me). And the reason why is the upper material, which is not flexible at all. I don't get it. They could have used their Primeknit and the Boston 12 would be a awesome shoe. I bought the shoe, because it felt great in the store. But about 10 minutes into my first run i had to realise, it's the worst thing my feet ever had to deal with. If you have wide feet, i highly recommend you not to buy this shoe, it's a nightmare. Or size up at least two sizes. And i already ran quite a few shoes till the end of their lifespan (Ultraboost, Solarboost, 2x Clifton8, Caldera6, 2x GT-2000, Deviate Nitro 2). For wide feet i highly recommend you to buy the Puma Deviate Nitro 2 instead. It's quite simmilar to the Boston, but you'll be able to finish your runs with a great pace and without any blisters.
I learnt today the adidas size guide and measurements are completely made up! I’m a U.K. 8.5 in Nike and Puma, based on the adidas measurements I should be a U.K. size 9.5. You can now see me performing in the local big top! I’m returning and exchanging, but based on this I feel I should be going for a U.K. 8.5 as the 9.5 was around two thumb width’s too long. Other than that it felt like a great shoe
DO NOT BUY THIS SHOE Boston 12…. How can adidas make an upper so bad??? Really think they are onto something with this midsole and glass fibre rods but that upper!!!! First run 8 mile run and will never wear them again. The material across the toe box is constrictive and the heel cup is a disaster. The heel cup from what I can see consist of three pieces of plastic or stiffer inner material. I know this because I have 3 blister on each heel. The shoe was even uncomfortable to walk around in. When you spend over £100 on a pair of shoes and have to consign them to the bin after 8 miles is ridiculous.
Thanks for the comment, I was thinking about getting them but seems like adidas have some problems with b12 upper durability and also comfort. Your comment was the final point of the story. I will buy another pair of deviate nitro 2 lol))
I always wait for nicks seal of approval before buying. My wallet hates you Nick
Haha this will last a while if you do pick it up!

Hi Nick, thanks for this review.
The fit of the Speed 3 did not work, and I suspect the deviate nitro 2 to be a little bit too stiff and causing a small injury above my ankle.
As I fell in love with the Takumis, I am considering these Boston for daily training and speed work and long runs and the adios pro 3 for eventually racing, but also long runs when the volume will be high.
Your opinion helps a lot, I think I'll give them a try and compare with the Puma.
Recently bought a pair of the 11s prior to the launch of the 12. They're unwearable. Felt great for the first run but on the second it was immediately obvious that the sides of my big toes rubbed the inside of the shoe on both sides (I'd even gone half a size up) and length wasn't an issue. The main problem though was the heel counter, it's just awful and the stitching created a pressure point which made blisters inevitable. Please correct me if I'm wrong, but from what I can see, that doesn't look like it's been addressed in the 12.
I received my Boston 12. I have a problem with the heel counter, I find that it is not tight enough.
Comparable to the Novablast 4 & Endorphin Speed 4??
My son is looking for a different pair to switch out his weekly runs and he loves his novblast 4s.
Any suggestions?
Just how firm is the ride on this shoe? How accommodating is it towards runners with higher arches and wider forefeet?
Umm maybe the Boston 12 is a good example of a shoe that does not scale that well for those with larger feet. My UK 13.5 is about 340g and so a good 60g more than the Speed 3. OK it is lighter than the Boston 11 but still feels clunky and the 11 actually fitted me better as found the 12 quite voluminous up front but I do have relatively very narrow feet. For faster work I would take, from adidas alone, the Adios 8, Takumi Sen 9 or Adios Pro 3 everytime over these and all of them are "lightweight" even in my size and I find them fine for slower paces or going for longer runs. Did any of the other Run Testers try this one? Nick always has good insight but equally his paces are way faster than an average runner. In general "super trainers" largely for the weight reasons I alluded to seem a miss for me and anyway Superblast not even offered in my size. I tend to use the carbon racers like the Rocket X2 or Adios Pro 3 I don't like enough to race in but are good for uptempo runs as I don't have the huge weight penalty the lower tier shoes have in my size.
I have wide feet and it fits me great.
Adidas has wide version of this shoe available too.
How’s the length? Some reviews say that it fits long. Versions 10, 11 fit me well
@@williamcass68 in all Adidas I am half a size down. Buy the same as 11.
@@williamcass68 v12 fits slightly longer length wise, whereas v10 and v11 fit a bit shorter and snugger. I’ll say stay true to size in v12.
I have an underpronation on one side, and am looking for an alternative to the invincible 3 im currenlty using (which are great, but a bit boring), how are these shoes for stability? as the INV 3 are very good.
Okay I’m still getting the Boston 10’s 😂😂😂. But these are something to think about having in the mix.
Great review. Just wondering how this shoe compares to the On Cloudmonster and if you had to choose one, which one would it be? Thanks!
Boston 12 or Endorphin pro 3 👀 I honestly prefer training in Pros over the Speed. Speed to me have been bottoming out because I’m more over a power runner.
Please could u do Boston 12 vs Superblast ?
I want a do-all super trainer for everything except race day. 5k -1/2 distance , easy runs , tempo and intervals. Should i get this or the saucony pro 3? I can buy 2 of these for the price of 1 saucony.
what garmen watch series are you wearing ?
Can B12 be used as a daily trainer?
Yes
great review,
Would love to know how Boston 12 compares with New Balance SC Trainer v2.
What is overal stability?
Can this be succesfully used for light over pronators?
I'm aware that this is not stability shoe, but I sucessfuly use trail shoes that are just stable (Nike Pegasus Trail 4)) in my ratotaion with Brooks Adrenaline.
I find the Speed 3 mushy in a long run. Boston 12 stays fresh. Alone Speed 3 unstable at slow pace and Boston 12 very stable at any pace. Puma Deviate Nitro 2 fastest and upper more comfortable but again Puma Deviate Nitro 2 hates the slow paces and Boston 12 stable at all paces but Boston 12 feel bottom heavy at slow (recovery) pace.
Love the channel and your reviews! I'm hearing great things these at the moment! I'm looking for a shoe to train for and, ultimately, run London marathon in (around 4 to 4.5hrs) I've been running in stability shoes for years (adrenalines / guides / NB860) but I've recently started using stable neutral shoes like Hoka Mach 5's and just did a fast 10k race in Endorphin Pro 3's with absolutely no stability issues. Have you got any suggestions for shoes I could look at for the marathon? Many thanks.
Hi Nick, you compared this to the Puma deviate 2, but how would you compare it to the deviate elite 2?
Hmm interesting one! Elite 2 is lighter, faster for reps. less stable and cushy for the kind of relaxed long run I did today, but probably a fair bit of overlap there! Boston cheaper of course, and would expect longer lasting
Thanks just purchased!
Thanks. But I have no idea why any runner would use a shoe positioned as a daily trainer as a track shoe? Addidas has a few options for tempo shoes. Otherwise, the rest of your review makes sense.
Versatility is always a good thing! It’s great to have a shoe you can use for a bit of everything, especially if you don’t want a big shoe rotation. As someone who’s mainly a marathoner I also like a fairly cushioned shoe even for track since I rarely do all out short reps, so if I don’t use a carbon racer I tend to use shoes like Boston 12 or Endorphin Speed 3 rather than flats/spikes
Wonder which one will pass the durability test… B12 or SuperBlast…
Very likely the B12
We need a Boston 12 strung
Is boston 12 same technology with adios pro 3 ?
Any chance of a speed tempo training partner shoe comparison vid.
Ie the speed, magic speed, this mach x, nb trainer 2 and the likes.
Do any of the run testers have issues with Achilles pain? Trying to find a shoe that will get me through longer runs that will keep me pain free (puma velocity 2 has done the trick for daily training/shorter runs)
Asics Novablast works for me!
Have had some Achilles issues in the past and the Adios Pro 3 absolutely babies my Achilles on Long Runs. Can’t say the same about other shoes.
Hey, do you recommend this for 5k - 10k run?
Hey Nick nice review.. I tried the shoes in store and I found that the lateral side of the heel was not level with the medial side (lateral side was not touching the ground), making it I guess not very stable at the heel.. Is it safe for a heel striker? All my shoes have significant wear on those lateral heel sides.. thanks
I had a hard time running on straight uphills when using this shoe, that's what I have observed.
Don't we all mate! Bloody uphills 😅
Only got 16 miles on mine so far so. But I do think they hit a spot the saucony speed 3 was missing. Upper isn't as soft or comfortable as the speed 3 but it's noticeable but doesn't seem to cause issues so far.
I've always heard the adidas foam needs to break so will see what difference that makes when it happens.
@@SergiuSalcau00lol 😂😂
@@SergiuSalcau00 speed for a start.
Injury risk- The upper and laces on the Boston 12 are terrible. It's fine for shorter distances, but over longer runs or hills it causes heaps of pressure on the metatarsal & tarsal area of the feet. Disappointing as I'll need to ditch mine since it caused an injury. The lower is actually excellent.
Hi, good review. Just curious for my own comparison. What is your heel to toe measurement in cm?
I'm trying to hold off buying any more shoes and you're not helping Nick! Quick question, I can get Adios Pro 3 for £157 and Prime Ex Strung for £167 from SportsShoes (before 10% club discount), would either of those be a better option than the Boston 12 at those prices?
review the noosa 15... the best trainer 2023... ;)
aye they missed it last year and also missed the glideride
A question for you. You guys refer to shoes as being ‘true to size’ does this mean you classify them as being a like for like e.g I’d buy them in a size 8 if I measure a size 8 normally or does it mean you true to size for the say half size you would add on normally? I’m a bit confused as I have just bought some triumphs in my normal dress shoe size as Saucony website puts this as at least 5mm longer than this size would normally be in a dress shoe…
For me it means true to the size you usually take in running shoes and particularly from that brand as in UK sizes especially some brands numbering is different. For instance in UK sizes adidas, Hoka and New Balance is 0.5 UK size more than the same length shoe in Nike, Saucony, Brooks & Puma.
❤❤❤❤very nice
I had to go size down haha!
I must be the only person who really didn’t like the endorphin speed 3. They’ve given me consistent heel blisters and speed sessions in them are very hard on my forefoot (really bad blisters too). Not only this but the branding and logos literally started peeling off after my first run. That was my experience anyway 🤷♂️ doesn’t seem to match up with the constant praise I see that shoe getting
please compare to takumi sen
Takumi Sen is lighter and all-out faster. Less stable and I wouldn’t cruise a long run in them like I did the Boston today. Takumi a pure racer and session shoe for me, and best up to half distance, Boston can go longer
Super trainers are a hard sell for me at their list price… you can find the New Balance SC elite v3, the Adios Pro 3, and the Vaporfly 2 for about the same price (or even a little less) right now. I’d rather buy any of those than a full price super trainer.
Where can you find any of those shoes at this price? I'd love to know ...
@@robhughes645Exactly. I call bull sh1t 😉
Did my first run today in Boston 12... Great shoe.. Only improvement for me would be a bit more padded tongue which would help get the shoe on... It's a bit floppy and basically the same as the Takumi Sen 8. For a more daily trainer it should be a bit easier to get on and off.
Lacing system is a good idea... Very easy to cinch down.
The ride is top as is midsole comfort. Outsole is good as usual.
I’ve historically used Pegasus and spent a few weeks in a new balance prism which felt great just a little too firm. Going back to Pegasus I’m finding my legs ache and soleus is sore too.
Is the Boston 12 a decent alternative to pegs?
I have both. Yes, it's superior in every way. Peg has a better outsole for light trail; that's it though.
What would you choose for a daily trainer? This or Novablast 3 or should I go for the adios pro 3?
Great review Nick. I’m looking at ordering a pair of these last pair I had was the Boston 9 but I had to half size up in them would you say the same with the 12 or so they run slightly bigger.
The Boston 12 could be a quite nice running shoe. But it's not (at least for me). And the reason why is the upper material, which is not flexible at all.
I don't get it. They could have used their Primeknit and the Boston 12 would be a awesome shoe.
I bought the shoe, because it felt great in the store. But about 10 minutes into my first run i had to realise, it's the worst thing my feet ever had to deal with. If you have wide feet, i highly recommend you not to buy this shoe, it's a nightmare. Or size up at least two sizes.
And i already ran quite a few shoes till the end of their lifespan (Ultraboost, Solarboost, 2x Clifton8, Caldera6, 2x GT-2000, Deviate Nitro 2).
For wide feet i highly recommend you to buy the Puma Deviate Nitro 2 instead. It's quite simmilar to the Boston, but you'll be able to finish your runs with a great pace and without any blisters.
I learnt today the adidas size guide and measurements are completely made up! I’m a U.K. 8.5 in Nike and Puma, based on the adidas measurements I should be a U.K. size 9.5.
You can now see me performing in the local big top!
I’m returning and exchanging, but based on this I feel I should be going for a U.K. 8.5 as the 9.5 was around two thumb width’s too long.
Other than that it felt like a great shoe
I never ever agreed with yr comments on the fit 😂
The heel flap looks so bad. I’m amazed Adidas keep persisting with it.
It's merely a fold down pull tab. It's quite effective.
Haha, it's great, guess those people at Adidas don't know what they're doing though ... 🤣
Is it me or this video slightly sped up?
❤✔️👍
DO NOT BUY THIS SHOE
Boston 12…. How can adidas make an upper so bad??? Really think they are onto something with this midsole and glass fibre rods but that upper!!!! First run 8 mile run and will never wear them again. The material across the toe box is constrictive and the heel cup is a disaster. The heel cup from what I can see consist of three pieces of plastic or stiffer inner material. I know this because I have 3 blister on each heel. The shoe was even uncomfortable to walk around in. When you spend over £100 on a pair of shoes and have to consign them to the bin after 8 miles is ridiculous.
Thanks for the comment, I was thinking about getting them but seems like adidas have some problems with b12 upper durability and also comfort. Your comment was the final point of the story. I will buy another pair of deviate nitro 2 lol))
Asics Superblast is a better shoe but the price...
Prime X is better than superblast
@@kbrennan4115 Prime X unstable and not for heel striker.
@@i.p2088it’s very stable. You need to have good mechanics to run in them, definitely not a heel striker shoe.
Can you give me this shoe?
Still a good chunk of EVA. Nope. 💩
I received my Boston 12. I have a problem with the heel counter, I find that it is not tight enough.
