These socks require no special setup beyond putting them on. For optimal fit and to ensure the plantar support aligns correctly, smooth out any wrinkles after placing them on your foot and calf. They are highly compatible with most athletic footwear, including running shoes, football cleats, basketball shoes, and training sneakers. To care for your Nike Classic II Cush OTC socks and maximize their lifespan and performance, machine wash them in cold water with similar colors. Avoid using bleach, as it can damage the fabric's performance properties. Tumble dry on a low setting or air dry to preserve the elasticity and shape. Do not iron or dry clean.
