Q2) to provide a better grip

Answer 2

Answer:

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 . thus , this is due to the fact that friction causes wear and tear of objects and reduces the life of the object .

The soles of the shoes have grooves in order to increase friction between the surface of the floor and the soles of the shoes. This prevents slipping on the floor.
