I wore them on a hike in Bear Mountain, NY that included a challenging rock fight (Major Welch Trail). They have held up very well. Excellent grip on smooth stones. Comfortable. Neither during nor after pain in the legs. Fit wise they seem to run small - I'm 6.5ft in the US and ordered a size 7 and they were still snug. Not cramped, mind you, but quite snug. Perhaps they will expand as they are used, but for now there is no room for error.
