Sportsmen use spiked shoes to improve their performance.
Most people think of spikes as something that can be used to puncture holes in the sides of cars, but these sharp objects are also used by sportsmen and women to improve their performance. For example, footballers use them on the soles of their boots to help them gain a better grip on the pitch. This allows them to stop and start more quickly and makes it easier for them to change direction. In addition, many sprinters wear spikes on their running shoes so they can dig into the track or road surface and generate more power with each stride.
