To use these bike socks, simply put them on like you would with any regular socks. When you're riding your bike, they'll keep your feet comfortable and blister - free. As for care, it's best to wash them in cold water on a gentle cycle. Avoid using bleach as it may damage the mesh and the color. Hang them to dry instead of using a dryer to preserve their shape and durability. Make sure to check for any signs of wear and tear regularly, especially on the double - stitched heel and toe areas. If you notice any loose threads, you can carefully trim them to prevent further fraying.
