• A callus is a patch of compact, dead skin.

  • Friction or pressure causes these thick, hard, dead areas of skin. Calluses tend to spread out more and can appear anywhere something rubs on your skin. If thickening occurs on the top of the foot (or toe), it's called a corn.

  • A plantar callus is a callus on the bottom or plantar surface of the foot.

Dr. J. Leonard Knudson can trim calluses on your foot or correct them with surgery. 

The procedure is painless because the skin is already dead. Additional treatments may be needed if the corn or callus recurs. People with diabetes, poor circulation, or other serious illnesses should have their feet checked regularly.
