Noticing dark spots on your feet can be unsettling — especially when they seem to appear out of nowhere. Whether they show up on the tops of your feet, the soles, or even between your toes, these spots can range from harmless pigmentation changes to signs of underlying health concerns. Before you panic or brush it off, it’s important to understand what might be causing these changes. From simple bruises to serious conditions like melanoma, your feet could be sending you vital clues about your overall health. Let’s dive into the possible causes, what to watch for, and when it’s time to seek medical advice.

Chronic Pressure or Friction
Friction can cause thickened skin and pigmentation.
- Corns and calluses form from repeated pressure.
- Tight or ill-fitting shoes worsen these issues.
- Proper footwear and padding help prevent spots.
| Cause | Symptom | Treatment |
|---|---|---|
| Corns | Hard bumps on feet | Padding and shoe adjustment |

Diabetes and Dark Spots
Diabetes can cause skin changes, including dark spots.
