Keep your feet happy in On’s Low Sock. On created the Low Sock with a precise, anatomical fit and ultralight, minimalist design. The sock hits just below your ankle bone so it hides out of view under your shoe, but it has a higher heel tab to protect your Achilles tendon against chafing and blisters. Designers used a blend of polyamide and elastane for a snug fit and soft feel, and they enhanced the sock’s breathability by using technical mesh paneling across steamy areas. Whether you’re logging miles on warm summer days or cruising as the temperature drops, the On Low Sock will keep you comfortable. If you want to show off your style, try the On Mid Sock or the On High Sock. Both socks are cut longer to protect against the elements. Sizing
