caption_attribution_description: English: Two types of track spikes. On the left is a pointed spike (needle) for a dirt surface. On the right is an 8-millimeter compression tier (Christmas tree) pin for use on synthetic tracks.
context_page_description: Track spikes, or just spikes, are racing shoes used by athletes when racing on the track. Some spikes are designed for longer-term training on tracks, but generally the shoes are used for racing. The term "spikes" can also refer to track shoes featuring such protrusions, though these are technically called pins. Spikes are similar to studs, which are used for team sports, although generally smaller and with a sharp point.
context_section_description: While most spikes are between 3/16 inch (5 mm) and 1/2 inch (12 mm) long, the most common is 1/4 inch (6 mm). Additionally, there are various specialty lengths, as well as minimal "blank" spikes (also called studs) 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. Track spikes create 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. A variation for synthetic tracks is the Christmas Tree spike. It uses a terraced cone shape with a flat end designed to compress rather than penetrate the track below it. However, the notion that the compression spikes have less track penetration is not supported by scientific studies. Since it does not penetrate the track surface as much as a pyramid spike, it may reduce wear on the track. Since the end is flat rather than pointed, it is less harmful to other runners in the event of being "spiked." Lastly, there are Tartan spikes that are dull that are most commonly used for rubber tracks.
