Every sport has proper gear you need to have in order to effectively compete. Some sports require an entire uniform with helmets and pads while other mainly consists of the right shoes. Sprint shoes, 
oddly enough considering the name, are shoes especially made for running at full speed for short distances. There are also shoes for cross country, pole vaulting and almost any other type of sport you can name.
The right running shoes give you a couple of advantages when on the track or in competition. Not only can the give your feet the correct scientific traction for your running type but the can also keep you from injury. A slip whole running can result in strained and sprained or pulled muscles. Some strains and sprains may only be a minor irritation resulting in a couple of days off though some can result in permanent injury. Sprint shoes are considered a safety precaution.
Another reason for the right shoes in traction over and above not slipping. Traction gives a runner an extra push against the ground to help them reach speed. Sprint shoes are especially made to add that extra push where a sprinter needs it the most, at the ball and toe.
The sprint shoes consist of a light weight material, thin flexible soles and very little support at the heel, stiff inflexible soles at the ball and toe and pointed spikes also at the ball and toe are.
When running a sprinter will usually use mostly the ball of the foot and toe area. The heel of a sprinter almost never touches the ground so of course all of the reinforcements are in the ball and toe area.
You should also always remember, no matter what the sport, you should replace your track shoes every 6 months or so. The spikes on the sprint shoes could become worn down and they will lose their traction and could actually become dangerous to wear. An uneven stride can cause uneven wear patterns and cause problems with the bones and muscles in your legs later as well.
You need the right shoe if you are going to compete in any sporting event but especially for track. Sprint shoes are specially made shoes to enhance your performance, lend speed and traction as well as keep you from slipping and falling on rough ground. Every race needs an advantage a sprint shoes can give sprinters that little extra they need.
