Wearing shoes that fit correctly is one of the most important ways to reduce pressure and friction that lead to corns. Choosing footwear with a wide toe box, adequate cushioning, and avoiding high heels or narrow designs helps offload bony prominences of the toes. Proper shoe fit prevents the hard core of a corn from pressing into deeper tissue, improving pain with walking. Regularly checking shoe size—especially in people with foot deformities or changing foot structure—can further reduce recurrence. When combined with orthotics and periodic skin care, well-fitting footwear is a key long-term prevention and treatment strategy.
