Imagine your foot is like a sandwich, the skin is the bread, and everything inside is the filling. When you walk for a long time, your shoes rub against your skin. This rubbing makes the skin start to separate from the layer underneath, creating a little pocket of fluid, that’s a blister! It's like when your hair gets tangled from brushing it too much.
Examples
- Walking all day in tight shoes causes blisters
- Riding a bike without socks leads to bubble-like sores on the toes
- A new pair of shoes can cause blisters after just one long walk
