Short Answer

Examine different types of shoes, including sports shoes and thongs. In terms of physics, why are the bottom surfaces designed as they are? What differences will dry and wet conditions make for these surfaces?

The bottoms of shoes and thongs are made to be extremely flexible.

When the surface is wet friction is mostly dependent on material.

Step by Step Solution

Definition of Shoes

A shoe is a type of footwear that provides protection and comfort to the human foot.

Determining why the bottom surface of shoes designed

The bottoms of shoes and thongs are made to be extremely flexible. The shape of the bottom shows what part of the foot holds the weight of the body while its texture is connected to the grip.

Sports shoes are required for activities such as running and leaping. There should be a proper balance between the surface and the shoes during all of these sporting activities. Therefore, the base of sports shoes is designed to maximize the force of friction while the bottom of thongs are comparatively less treaded because their purpose is just to walk which does not require more friction.

Determining what difference will make for surfaces

Running shoes have fillisters for better grip and bumpier surfaces on the other hand thongs have better friction on smooth surfaces. When the surface is wet, friction is mostly dependent on the material.
