The 1000 Mile Active QTR Sock provides maximum comfort and support at all times. The arch bracing and heel give firm grip and no-slip stability. Super soft yarns and flat toe seam reduce irritation on the skin whilst the padded heel, toe and ankle offers cushioned protection. Ventilation panels on the top of the foot increase air flow and allow the foot to breathe. This single layer sock is knitted to an ankle length for those who prefer a shorter sock.
