“I bought my first pair of these almost 15 years ago from a man in an rv at Atlanta Motor Speedway. I still wear those same two pairs today. They have been to the highest point in the US and the lowest. I finally bought two more pairs and I bet they last just as long.”

“Wore these on a mountaineering trip in Nepal up to 20k feet and just bought another pair for Denali this summer. Perfect for tall 6-8,000 meter mountaineering boots. Zero blisters and super warm.”
