What are corns?
Painful corns on the feet are a very common foot condition that can make everyday activities such as walking, exercising, and wearing shoes uncomfortable. Corns develop when an area of skin is exposed to repeated friction or pressure, causing the skin to thicken as a protective response. They are commonly found on the tops and sides of the toes, between the toes, and on the soles of the feet, particularly over bony areas.
There are two main types of corns: hard corns and soft corns. Hard corns are small, dense areas of thickened skin that usually form where footwear rubs against the toes. Soft corns typically develop between the toes where moisture becomes trapped, leaving the skin softer but often very tender and painful.
Many people confuse corns with calluses or plantar warts (verrucae). However, foot corns are usually more localised and are often painful when direct pressure is applied during walking or running. Some people describe the sensation as feeling like they are walking on a small stone or splinter inside their shoe. In some cases, a tiny central core may also be visible.
A podiatrist can diagnose and treat corns safely and effectively. One of the most common podiatry treatments for corns is sharp debridement, where the thickened skin is carefully reduced using sterile instruments. This treatment can provide immediate pain relief and help reduce the risk of complications, especially for people with diabetes, arthritis, or poor circulation.
Preventing corns from returning is just as important as treating them. Podiatrists often use pressure offloading techniques such as felt padding, silicone toe wedges, or custom orthotics to reduce friction and pressure on the affected area. Footwear advice also plays a major role in corn prevention. Shoes that are too tight, narrow, or shallow can increase pressure on the toes and contribute to recurring corns. Choosing supportive footwear with a wider toe box and adequate depth can significantly improve comfort.
Regular podiatry appointments can help manage painful corns, improve foot comfort, and keep you active. If you are experiencing ongoing foot pain, corns, or pressure areas on your feet, a podiatrist can help identify the cause and provide the most appropriate treatment options.
