To use your Nike Classic II Socks, simply ensure you are putting the `Left` sock on your left foot and the `Right` sock on your right foot for the intended anatomical fit. These socks are designed for `adult` `Unisex` wear and are compatible with a wide range of athletic footwear. They are particularly suited for team sports and individual training. For care, it is generally recommended to machine wash socks in cold water with similar colors and tumble dry on low. Avoid bleach and ironing to maintain the integrity of the `Dri-FIT` fabric and elasticity. Info needed: Specific washing temperature and drying instructions to preserve fabric technology.
