Question

Why are soles of shoes rough?​

Answer 1

Answer:

Grooves on the soles of shoes make the bottom surface of the shoes more rough. Due to increase in roughness, the frictional force between shoes and ground increases. The increase in friction gives better grip for the person with the ground and won't fall down easily.
