Risk factorsBy Mayo Clinic staff
These factors may increase your risk of corns and calluses:
- Bunions, hammertoe or other foot deformities. A bunion is an abnormal, bony bump that forms on the joint at the base of your big toe. A hammertoe is a toe deformity in which your toe becomes curled up like a claw. These conditions and other foot deformities, such as a bone spur, can cause constant rubbing inside your shoe.
- Not protecting your hands. Using hand tools without wearing gloves exposes your skin to excessive friction.
