How to Manage a Plantar Foot Callus: Podiatrist Guide

Why Calluses Form Under the Ball of the Foot

Calluses develop when skin thickens to protect underlying tissue from excessive pressure or friction. Unlike corns, calluses cover a broader area and lack a hard central core. When pressure concentrates on specific areas, such as beneath the fifth metatarsal head on the outer foot, the skin thickens over time and can cause discomfort during walking if left unmanaged.

Podiatric Care and Pressure Offloading

Clinical debridement using a sterile scalpel safely removes the toughened outer layer without injuring underlying skin. To slow down regrowth, podiatrists offload pressure using orthotic insoles positioned just behind the metatarsal head. Daily application of a foot moisturiser containing 10 percent to 40 percent urea (with 20 percent being a common recommendation) also helps soften hardened skin.

Key Steps for Managing Callus Buildup

• Have a qualified podiatrist safely pare down thick callus buildup using clinical instruments.
• Use orthotic insoles to redistribute weight away from sensitive metatarsal heads.
• Apply a urea-based moisturiser daily to hydrate and soften thickened skin.
• Wear supportive, well-cushioned footwear to minimize friction during daily movement.
