Why do the soles of our shoes wear out?

• A. Soles are of poor design.
• B. Soles are worn out due to friction.
• C. Soles are made of poor material.
• D. Shoes being too narrow.

Answer 1

The correct option is B Soles are worn out due to friction.

The soles of shoes are worn out due to the effect of friction. The soles of shoes increase the friction between surfaces because it makes the surface of the shoes rough. When we walk on the road, friction will occur between the soles of our shoes and the road so that slipping can be prevented. Thus the road wears out the soles due to friction.
