As a professional Mountain Bike Coach, i have tested kit to the max in all conditions! These by far are the best socks i have ever used. I do in excess of 100km a week running and these socks have out performed my £35 a pair ones, which i used to previously swear by. I used them whilst Mountain Bike Coaching too and again out perform all my other socks, they repel water well and draw all the moisture away from the foot, but the clever part is the wicking effect, they wick quicker than you cpuld imagine. The Left and Right feet labels are easy to see and if your buying just the 2 pair pack you cant get two left socks mixed up with the different colour socks.
I have covered 250km so far on my first pair and i have had them go through mud, water, washing machine and tumble drier.
I cant say enough about these socks, if i had any critism at all i would let you know, but i find them faultless.
A high performance sock, without the high performance price!
