The Coolmax Liner is designed to be worn underneath a heavier sock as a protection against abrasion and for moisture transport.
Blister Free Bliss
After investing in over a dozen different wool socks to prevent serious blisters while hunting very rocky terrain, I decided to give these a whirl and have never been more pleased with a sock purchase. The long treks that were once agony now make the trip a breeze - I have very tender feet and easily blister but using these I did not once feel any abrasion.
I love these socks.
I wear these socks every day, the men's size small fits well and I can vary the color to match what I'm wearing.
Great for hiking!
I wore these socks for all-day hiking in Yosemite and they worked great, as a sock (not a liner). No blisters, no bunching - just comfortable wicking socks. Great in the heat and cool or damp weather. I just ordered two more pairs.
