'Track spikes' are shoes used at most athletics (track and field) events. They are lightweight shoes with spikes screwed into their bottom, or spike plate, in order to maximize traction (and therefore performance) when running or jumping.
Near the front of the foot, there are usually 3 to 10 threaded holes where the spikes may be screwed using a spike wrench. There are usually no spikes near the heel, except for high jump and javelin shoes. Some spikes have permanent or "fixed" spikes.
While all track and field shoes that contain spiked soles are referred to as "track spikes", there are differences between sprinting, distance running, and field event shoes. Sprint spikes generally have more support, and a stiffer, more aggressive spike plate. They often are built minimalistically, with as little material and hence weight as possible. Some are additionally given zip-up covers for laces to improve aerodynamics. Distance spikes have a more relaxed plate, more heel support, and contain less spike points. They are built as much for support as they are for speed. Field shoes are very different, with each shoe configured for the demands of its event. The major manufacturers of spikes include Nike, Asics, Brooks, New Balance, Adidas, and others.
The spikes of the shoe vary in size. While most range between 3/16 and 3/8 in., with the most common being the 1/4 in, there are a number of specialty lengths, as well as minimal "blank" spikes used to cover a spike hole. The three main types of spikes are the pyramid, the neddle, and the compression tier (or Christmas tree) spike. Pyramids are conical spikes that taper to a sharp point. They normally have a maximum diameter nearly equal to the diameter of the threads of the spike. Needles also have a sharp point, but a thinner cone diameter. The purpose of both is to penetrate the track surface and so derive its traction from its position. The alternate variant for synthetic tracks is the Christmas tree spike. It uses a terraced cone shape with a flat end to, instead of penetrate, compress the track below it upon impact, and use the track's reaction force to in fact return energy to the runner, increasing his speed. It also reduces the damage incurred in the event of "spiking" or contact by the spikes with another runner. Spikes also come in either steel or ceramic varieties, as well as multiple colors (or unpainted).
Sprint spikes usually have the toe of the shoe pointing up, not touching the ground> This is called "taper" and is designed to make the runner run on their toes to run faster.
Common spike lengths are: 3 mm (1/8 in), 5 mm (3/16 in), 7 mm (1/4), 9 mm (3/8 in), 13 mm (1/2 in).
