I'm going with the SL2 for my interval training. I like to not rely too much on rods/plates during training as I do feel that nice difference on race day with my carbon plated shoes.
I used to come back from running with ankle pain, knee pain and hip pain. 5km is max for me on a good day. But I stopped enjoying it. Started again after seeing the SL2 comments and really having fun running in this shoe! (I'd get a1/2 size up next time ).
Great comparison. Is there any chance of comparing the SL 2 to the Adios 8? There’s been a lot of discussion on UA-cam about the Adidas line up and possible Adidas shoe rotations, but the poor old Adios 8 never gets a mention.
got myself a B12,would buy another pair,it is that good FOR ME,with proper running form,its bouncy and easily picked up paces,need some breaking in tho
I'm nearing 200K on my Boston 12 and it feels brand new in terms of midsole and outsole. I feel like SL2 and Boston overlap too much for me and I'm waiting for Adios 9 to release so I can have an even lighter and leaner training shoe.
Sl2 ran short for me. My first pair of Boston 12 is getting on and found another pair for a good deal so I guess it's a big vote of confidence going for them again. I personally don't think there is a better daily trainer. Probably going to buy Sl2 again but can't quite decide whether to go up 1/2 or full size. Toe was touching end for US 11, which is same size I have in Boston 12 and ts8 and Prime X Strung 🤔
Did you decide? Ive been looking at the JP measure when comparing as they use cm. I run US 12 for most every shoe at 30cm and the SL2 is a wild 1.2 cm shorter. Its almost a size and a half small! Which I've never seen before.
I really wish I didn't have a wider, higher volume foot because I found the SL2 to be a better feel than the Boston 12 was for me at the store. Obviously if I had put any serious miles on it I would feel that squeezing narrower shoes have almost right away. One day there'll be an adidas for me! Great video as always
Just the same here. SL2 didn't work for me right at the store.. wide feet, high volume and mild pronation do not match with SL2. I never had also any Adidas shoes because of my type of foot.
I am pretty sure I am getting some serious heel rub in the SL2. It is disappointing since I love the ride of the shoe. No issues with the B12 though. Both great shoes but the heel rub is a little issue for me with the SL2.
Do you still have heel rub issue with SL2? I got a mild heel bursitis from winter running. Not sure from which shoes. Bought SL2 because it had such a great lab performance in cold temperature. But heel rub is an issue.
@@sungtaekim507 I definitely do. It is not as bad anymore not giving a blister, but still there. I have found especially if I just wear them casually. Like I said it has gotten better, but I still get rubbing for sure.
Here in my country, there is no wide version for Boston 12. So I just grab the SL 2 Wide. Downside with SL2 Wide there is only 1 color the black and white. The black is not available in the physical store.
I just bought the SL2 on a whim seeing a buzz of decent reviews and its low price point. They arrived yesterday so not had a chance to run in them. Coming from a runner who normally wears a stability shoe (GT2000) what would you recommend as a good shoe to replace it with (other than another GT2000)
The Boston 12 is one of my favourite shoes as a heavier runner (250lbs), especially for tempo days but also great as a daily trainer for heavy runners.
I do not like the Boston 12 even if it's bouncy, the firmness of the ride can be felt between mid to heel which can cause pain to the foot arch. Then the heel counter is stiff, and heel collar could not properly support the heel. Possible Adidas SL2 is the best choice for this blog.
There is a shoe for everyone these days:-) I am 205 lbs and love Boston 12 doesn’t bottom out ; rods seem to work well for me and wider forefoot is a dream for me . I don’t like being in it over an hour then prefer softer shoes. My tempo daily shoes are Boston 12 if picking up pace at all. My race day shoe is adios pro 3 …. So maybe that is why I like .
Boston 12 drop = 7 mm SL 2 drop = 9 mm Just started to run in the Boston 12, only 20 km on it so far. Female, Asian, a bit less than 50 kg, but I don't feel the Boston 12 is stiff though (I did hear some female runners said it's kinds stiff to them). Cos the STIFFEST shoes to me so far is the Saucony Ride 15 😂 Gave me some ankle pain after the first 2 runs. Midsole only softened up after 50 km or so. Many said Saucony Triumph 20 is soft. I didn't find it soft though but not stiff either, just FIRM. And I find Boston 12 actually a softer shoe if compare to those 2 🤣 Currently in a dilemma. A local sports shop is selling the Boston 12 with a discounted price that's the SAME with the SL2!😂 But I lack a NON-plated shoes though. A few shoes on rotation but all with TPU / nylon plate (I can't really run on carbon-plated shoes except for Puma Deviate Nitro 2 which has a softer composite plate). Despite my light (?) weight, somehow I tend to pound on the road hard (same as Matt?😊) . So I realised with nylon-plated shoes, I felt MORE protection on my feet especially after the 7 km mark, at least I don't feel like I'm pounding directly onto the road which will then make every step kinda painful (luckily so far I'm just a 10k runner).
I don't know if this maybe be an inconsistency between pairs, but my Boston 12 was extremely firm and rigid out of the box. Literally felt like running with a brick strapped to my feet. People recommended I walked around in it (because it breaks in after around 40-50 K), but even that was extremely uncomfortable. Aggravated both an old knee injury, and my back on the first run. My perceived effort was through the roof... Now that it's broken in, it really sings on hill reps, but I really don't like it much for anything else. Too clunky for easy runs, and I have other shoes that do almost everything else better. But I do like the feel of Lightstrike Pro, so I just did my first run in the Adios Pro 3 this morning. That shoe felt comfortable right out of the box, and kept my heart rate lower. It even handles easy pace so much better than the Boston 12.
@@theghostofpcs2391 Really?! Sounded as if we're running in a totally different Boston!😅 Or maybe I'm just lucky? I bought it from the same shop I mentioned above (that time it was only 12% off), so I actually get to try the shoes b4 buying. I run VERY SLOOOOOWWW but I don't feel it's clunky at all. I won't buy any top-tier racing / carbon-plated shoes anymore. I've tried the Puma Deviate Nitro Elite OG & even Nike Vaporfly 2 (a birthday gift from my elder sis) & somehow they caused me pain at some WEIRD spots...😅
What I dislike the most about this video is that the SL2 color way you’re holding was not available in my size! It’s a great shoe though, even in the blah color way I had to get. At least I got 30% off though.
Another great comparison, thank you Matt. Could you possibly do a review of the Adidas Supernova Solution and compare it to Saucony Guide 17 and also do a comparison with the he old stable neutral Adidas Boston 10. I need a replacement for my Adidas Boston 10s. 😢
For walking I’d say 880s. The SL2 have a medial bias and makes it feel weird to walk in. Overall I’d suggest the 860 v14 as they have more support. I don’t like ultra squishy shoes.
I'm going with the SL2 for my interval training. I like to not rely too much on rods/plates during training as I do feel that nice difference on race day with my carbon plated shoes.
I really love the B12 however for someone reason I keep reaching for the SL2 for easy runs. The B12 are great for long runs and pushing the pace.

No baby no like. Love my B12s and I’m tempted to try the SL2
@@Shipwreckruns this comment made my day! -Matt
Try them, have them and they are absolutely fantastic and fun to run in
I hated the heel area in the Boston 12, and the big clunky lace loops

check out the adidas supernova solution. very stable and fast enough shoes.
Can I take SL2 on the track for sprints and intervals?

Is either suited for heavier runners? 250lbs plus
If you want to stay in the Adidas family, maybe the Adistar Byd for heavier runners, to get the most from the plate.
The Boston 12 is one of my favourite shoes as a heavier runner (250lbs), especially for tempo days but also great as a daily trainer for heavy runners.
Wow, did you already chewed the sl 2..?
I don't think so. That smooth part on the outsole comes like that. It looks way more drastic with the sole being dirty though.

All Adidas rods make my toes throb after 3 miles 😢
Exactly what I felt, I regret buy it, Triumph 20/21 way better and I ❤ DN2
I hated the 12s too, such a stiff and uncomfortable ride
Yeah, for forefoot strikers B12 is excellent.

Get these 2 and your preferred super shoe and you're rotation is all set
In terms of walking, which one would you prefer ?
Did you ever get an answer
sl 2 is 9mm but runrepeat cut it in half and measured closer to 8mm.
Trying to decide between Adidas SL2 or New Balance Rebel V3
1st marathon in sl2?
So for non elite runner..which one is the go to shoe
Ultraboost 5 vs these two?
You say the Boston 12 pitches you medially. Is it a similar pitch as the Adios Pro 3? Thanks.
Boston 12 drop = 7 mm

Hey matt have you run 32km run or 25 km on Adizero SL2? but would you recommend this as daily trainer for longer distance who runs at 80km per week?
should i go for SL2 the same size as boston (10)?
Wider toebox and lower drop on the Boston 12 makes it a winner. Also you can calm down a bit, I feel youre shouting at me haha. 😊
