Sprint shoes are the kind of shoes used mostly at athletic events. Sprint shoes are also known as track shoes or running shoes. Track shoes are typically made from lightweight materials and also have spikes or a spike plate screwed into their bottom. This helps maximize the athlete's performance when running. Near the front of the shoe there are 5-10 holes where spikes are fitted using a spike wrench. Generally there aren't any spikes near the heel; exceptions would be shoes made especially for high jump and javelin athletes. Sprint shoes with permanent or fixed spikes are also available. Sprint shoes are made to fit three types of running styles; these are 'Pronation', 'Supination, and 'Neutral'. Pronation means the ankle rolls towards the inside whilst running; Supination implies that the ankle rolls outwards and neutral is right in the middle while running. Pronator athletes will need a straight shaped pair of shoes, whereas supinator athletes would need a more curved pair of shoes. Pronators with flat arched feet need motion control shoes, however supinators with high arched feet need specially cushioned shoes. Sprinting shoes are quiet different from shoes that are used by long distance marathoners. Street running shoes are much softer and highly flexible. The spikes on the shoes also vary according to the intended purpose of use. Sprint shoes have spikes that are better supported and have stiffer spike plates. Distance spike shoes have more relaxed spike plates that are much lighter. Field spikes also vary according to the event they're used for. The spikes on sprinting shoes are essential, but using these spikes on the tracks wears the tracks out. Newer designs use compressed spikes also known as 'x-mas tree' spikes; these prevent the wear and tear of the racing track and also give good support to the athlete. Sprinting shoes are reputed manufacturers such as Nike, Puma, Reebok, New Balance, and Adidas are tried and tested by top athletes from around the world.
