You deserve the best gear - The best gear starts with the best fabric. It starts with Performance - Ultralight Dryarn® microfiber creates a lightweight, breathable sock that keeps your feet cool in summer and warm in winter, while being 2.5x more durable than ordinary cotton. We created the PERFECT fit - Integrated compression inserts on the midfoot create a firm, stable fit. Then we added a wide, double-layered waistband to keep sweat out of your shoes and hold your feet firmly to eliminate slippage. Going the extra mile: We've added extra support to the heel and Achilles heel, reducing the risk of sprains or injuries. Our products arrive pre-washed, eliminating the risk of shrinkage during washing.
