The basic cause for corns and calluses is only one, too much pressure, usually in combination with some friction. Some of the common Corns and Calluses causes include:
1. Footwear: The wrong footwear can create unwanted friction and cause corns and calluses, including
- Tight footwear
- High-heeled shoes
- Loose-fitting footwear
- Thin-soled shoes
- Wearing shoes without socks
2. Toe deformities: Deformities of feet such as hammer-toes result in uneven distribution of pressure on the feet and toes. Some regions receive increased pressure resulting in formation of corns or calluses.
3. Gait abnormalities: An abnormal style of walking can cause increased pressure at different areas of the sole of the foot. People suffering from arthritis or other joint problems walk in a typical style, which can cause increased pressure at certain points and contribute as one of the Corns and Calluses causes.
