Hammer toe

toe

Hammer toe is a term used to discribe a person whos toe bends downward and the middle joint curls up. This eventually results in the toe getting stuck into a claw-like position. When a person's shoe rubs against a hammer toe they can develope corns, blisters, and calluses that may form on the toe itself or on the bottom of their foot. This can make walking very painful.
