Resist the urge to trim or cut corns or calluses at home. This is one of the most common reasons for open wounds and infection. It's usually fine to use a pumice stone on the corn or callus, as long as you're gentle. Never scrub at the skin until you draw blood or experience serious pain, as it can be a quick path to infection. Until you get to the podiatrist, relieve pressure from the corn or callus with padded, supportive footwear. Your podiatrist may prescribe any of the following treatments for corns and calluses: Topical acids Foot padding Orthaheel or Powerstep orthotics Vionic shoes with Orthaheel Trimming the skin If you have chronic corns or calluses, your podiatrist will help you put a plan into place to prevent a recurrence. Wearing shoes that fit properly and using protective padding on vulnerable parts of your foot can be highly effective in preventing corns and calluses.
