The Fox River Wick Dry Therm-A-Wick Liner Tube Socks are ultra-lightweight, heat-retaining liners that feature Fox River's Wick Dry technology, keeping your feet dry and blister-free. Thermolite is a hollow-core fiber that heats up quickly and holds in heat well, so you stay warm, while retaining the characteristic ultra-thin fabric weight of a liner. Liners, which are meant to be worn between your feet and socks, serve as a friction barrier. The Thermolite liner can even be worn as a primary sock when an ultra-thin, lightweight sock is required and is a favorite of hockey players. The soft inner liner can move with your feet without bunching, which prevents those blisters that would otherwise crop up when hot spots constantly rub up against a thick sock that doesn't move. Additionally, liners help to keep your feet warm and dry on cold hikes by using the same layering principle you already apply to the rest of your body.
