Question

Atheletes wear shoes which have spikes on them.why

Answer 1

The 'spikes' generally add traction to the shoes, allowing them to grip the ground better and keep from slipping and falling. This can be seen in football or soccer shoes, where the field can become wet and muddy, which could cause slippage if the shoes didn't have extra traction. Most 'spikes' are made of rubber, though you can find higher end shoes with metal spikes.
