To use these socks, simply put them on like any other pair of socks before you go cycling. You can wear them in hot or cold weather as they're suitable for a wide range of climates. As for care, it's best to wash them in cool water to keep the wool in good condition. Avoid using harsh detergents that might damage the fabric. And don't dry them in a high - heat dryer; instead, let them air - dry. Also, check for any signs of wear and tear regularly, and if you notice any holes, it might be time to get a new pair.
