Blisters can form on any part of the feet. This is where there is a small pocket of clear fluid on the upper layers of the skin, usually because the outer layers of the skin have been damaged by either:
Friction - from shoes rubbing
Chemical or heat burns
Sports people are prone to developing blisters, in particular those sports that involve a lot of pivoting.
