Familiarity: I've put it through the wringer
Grand Canyon Rim to Rim
8:20 of hiking
I know it takes more than these liners but they really do work well. I wear Altra Olympus shoes (one full size "too big") and fairly heavy merino wool socks over these liners but the system worked and worked well. These liners are well made and comfortable. I wear a 9.5 in most shoes (I wore 10.5 Altra's on this hike) and a medium sock fit perfect.
