Pressure and friction from repetitive actions cause corns and calluses to develop and grow. Some sources of this pressure and friction include:
- Wearing ill-fitting shoes. Tight shoes and high heels can compress areas of your feet. When footwear is too loose, your foot may repeatedly slide and rub against the shoe. Your foot may also rub against a seam or stitch inside the shoe.
- Skipping socks. Wearing shoes and sandals without socks can cause friction on your feet. Socks that don't fit properly also can be a problem.
- Playing instruments or using hand tools. Calluses on your hands may result from the repeated pressure of playing instruments, using hand tools or even writing.
These approaches may help you prevent corns and calluses:
- Wear shoes that give your toes plenty of room. If you can't wiggle your toes, your shoes are too tight. Have a shoe shop stretch your shoes at any point that rubs or pinches.
- Use protective coverings. Wear felt pads, non medicated corn pads or bandages over areas that rub against your footwear. You can also try toe separators or some lamb's wool between your toes.
- Wear padded gloves when using hand tools. Or try padding your tool handles with cloth tape or covers.
