Shoe-Related Skin Problems: Blisters, Corns, Calluses, and More

Ill-fitting shoes cause friction and pressure leading to:

• Blisters: Fluid-filled pockets from shear forces; painful, infection risk if ruptured.
• Corns: Focal hyperkeratosis over bony prominences (tops/sides of toes); hard or soft (between toes).
• Calluses: Diffuse thickening on weight-bearing areas (ball, heel); protective but can become painful.
• Skin irritation: Redness, itching, inflammation.
• Nail problems: Ingrown toenails, subungual hematoma, fungal infection, nail loss.
• Bunions (hallux valgus): Narrow toe box forces big toe laterally → joint enlargement, pain.
• Heel spurs/plantar fasciitis: Poor arch support → plantar fascia strain → heel pain, calcaneal spur.
• Metatarsalgia: Forefoot pain from inadequate cushioning/support.

Prevention

• Proper fit: toe box width, length (½ inch beyond longest toe), arch support.
• Shop late afternoon (feet swollen).
• Rotate shoes; replace worn-out pairs.
• Moisture-wicking socks.
• Orthotics if biomechanical issues.

See a podiatrist for persistent pain, deformity, or diabetes (high ulcer risk).
