Toe covers are absolutely essential for road bikes and other cycling in the winter. They fit perfectly on SPD-SL and similar systems. Because they are white, they will look great with white shoes. The fabric is sturdy, and they can be used warmly to protect your toes from the cold. For those who want to use shoe covers in a simple way, etc. (The photos are of my own item, an example of being attached to a size 40 shoe) Brand new, unused item. The size is free size. Thank you for your interest.
