What common footwear issue can lead to the development of soft corns?

Narrow fitting shoes often lead to the development of soft corns due to the pressure exerted on the toes. When toes are compressed together in a shoe that does not allow them adequate space, it can cause friction in specific areas, which leads to the thickening of the skin, resulting in soft corns. Soft corns typically form between the toes or on the top surfaces of the foot where the skin has been consistently irritated by the limited space.

While high heels can also contribute to foot problems, they are more likely associated with a variety of issues including calluses and bunions rather than specifically soft corns. Sandals and open-toed shoes generally allow for more airflow and space for toes, reducing the likelihood of soft corns. Consequently, narrow fitting shoes are the primary culprits when it comes to the development of soft corns due to their constrictive nature.
