The Most Common Answer: Corns and Calluses (Not a “Mystery Disease”)
Yellow bumps on feet are often just thickened skin from pressure and friction.
Think of it like this: when the shoe keeps rubbing the same spot, the skin “panics” and thickens to protect deeper tissue.
Corn vs. Callus: How They Look in Real Life
- Corn: small, round, more “dot-like,” often on the top or side of toes, sometimes with a firmer center (“core”).
- Callus: flatter, broader patch, often on the ball of the foot or heel.
The yellow color is usually compressed, dead keratin (a normal skin protein), packed tight by pressure.
