A good cloth tape can help save the toes of your shoes if you use metal toeclips and don't use cleats. Wrap the tape around the area of the toeclip where the shoe will make contact. When properly set up with cleated shoes there's supposed to be about 1/8" of space between the toeclip and the toe of the shoe. The toeclip's main purpose is to hold the toestrap.

Wrapping the toeclipc also reduces the transfer of cold to your toes.
