Thermolite® Polyester
A lightweight fiber providing breathability and warmth while moving moisture away from the foot. Thermolite does this by combining a thermally efficient polymer and a micro-tested hollow core that heats quickly and retains warmth.

Wick Dry® Technology
Our exclusive technology quickly draws moisture away from your skin so your feet stay dry and comfortable. Removing the moisture build up reduces hot spots and friction that causes blisters.
