I've used their lower model in 4 different pairs and always felt good, the sole eats a lot after 500Km of Hikes with irregular terrain, especially gravel, stones, etc... Running with small elevation gains seems to lower the wear on the sole. Only problems I got were on a pair after soaking them much and hiking with them but nothing serious. btw I just got the 5th pair and not one single problem on the lace system.

How long would they last you? Can they around 20-25kg? Recommend for a week's walk?
I would think so assuming your load isn't too heavy.
***** I've gone with the Keen targhee mid 2 because I am flat footed and they were very comfy.
