Engineered to make a difference in the field, and protect what’s most important on any hunt, your feet! The Piston is constructed with compression throughout the entire calf, specifically designed to lock both the sock and your muscles in place, while promoting circulation. An extra thick footbed for cushioning, not typically offered in compression socks, rounds out the construction – allowing it to be a true game changer for extended backcountry treks.
