. With the exception of high jump and javelin shoes, track shoes generally have no spike wells along the mid-foot or heel. Some shoes have permanent or "fixed" spikes which are not meant to be removed.

Track shoes are exceptionally light, some shoes weighing less than five ounces (142 grams) each, half the weight of many standard running shoes. However, as this is achieved through reducing the amount of material used in the soles and sidewalls, spikes offer less cushioning and support than a standard running shoe. Thus, constant use in training may increase the chances of injury.

In most track shoes, the toe region bends up to allow space for protruding spikes and to encourage athletes to run on their toes. This upward angle, known as "taper," varies widely depending on the intended use of the shoe, and the taper angle can be rigid or flexible. Shoes with a large taper are said to be "aggressive."

Types of Shoes

There is considerable variation among track shoes depending on their intended use.

Sprint spikes generally have a very stiff spike plate with the greatest number of spike wells. The taper is highest and most rigid in sprint spikes, maximizing the efficiency of energy transfer with each stride. Very little heel support is needed because sprinters spend most or all of their time on their toes. Sprint spikes may have a zip-up cover instead of or in addition to laces to improve aerodynamics. The fit of sprint spikes should be very tight.

Distance shoes have a more flexible spike plate with less taper and fewer spikes. Because of the longer race distances, support through the mid-foot and heel is as important as efficiency with distance spikes. This means that distance spikes generally have a softer, more durable sole, particularly through the heel region. Although still “glove-like,” the fit for distance spikes is generally slightly looser than for sprint spikes, given the longer race duration.

Middle distance spikes are a hybrid of a sprint shoe and a distance shoe, featuring an intermediate level of taper, spike plate rigidity, cushioning and support. Certain middle distance spikes are also popular among hurdlers because they have a relatively steep taper for sprinting and a cushioned heel for landings.

 spikes usually have no more than six spike points and are similar to distance spikes in many respects. However, given the wide range of terrain encountered off-track, cross country spikes have a more durable rubber sole and supportive mid-foot to provide a level of cushioning and stabilization not required on a track. Depending on race length, surface types and personal preference, cross country spikes may be abandoned in favor of racing flats

Types of Spikes

While most spikes are between 3/16 inch (5 mm) and 1/2 inch (12 mm) long, the most common being 1/4 inch (6 mm), there are a number of specialty lengths, as well as minimal "blank" spikes used to cover a spike well. Spikes are generally metal or ceramic and come in three main types: the pyramid, the needle (pin), and the compression tier (Christmas tree). 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 each is to derive traction by penetrating the track surface. Some tracks do not allow pin spikes and limit the length of pyramid spikes to minimize damage to the track. The alternate variant for synthetic tracks is the Christmas tree spike. It uses a terraced cone shape with a flat end to compress rather than penetrate the track below it and use the track's reaction force to return energy to the runner, increasing his speed. It also reduces wear on the track and is less injurious to other runners in the event being "spiked."
