It's been roughly 800km's of trail mileage since I received a pair of Fox River AXT-1 socks from www.runningfree.com.
It has been miles of trails and many river crossings. They have held up well to the abuse. They drain well after being submerged during river and creek fordings. Even when wet these wool athletic socks are still comfortable.
Gotta give the guys at foxsox.com for the AXT-1's as they sure can take a beating.
