Callus – Patient Information

What is a Callus? 

A Callus is a thickened, rough patch of skin that forms in response to repeated pressure or friction, much like a corn. However, calluses are generally larger, less defined, and have diffuse edges compared to corns. 

• Location: Usually on the soles of the feet — especially the ball of the foot (beneath the toes), heel, or sides of the foot. They can also appear on the palms of the hands 
• Shape and Size: Broader and more spread out, without the distinct central core that corns have 
• Texture: Rough, dry, and thickened skin 
• Pain: Typically painless, but may cause discomfort or irritation if very thick or if they press on sensitive areas

Common Cause 

The common cause of Calluses is usually from too much walking or running with repeated pressure or friction, which tends to cause calluses on the bottom of the feet (the soles).

Treatment 

• Footwear: Choose comfortable, well-fitting shoes with cushioning 
• Foot Care: Regularly moisturize and gently exfoliate with a pumice stone
• Protective Pads: Can help reduce pressure on specific areas 
• Medical Care: If very thick or painful, a podiatrist can safely pare-down or treat calluses
