While most spikes are between {{convert|3/16|in|mm}} and {{convert|1/2|in|mm}} long, the most common is {{convert|1/4|in|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.<ref>{{Cite news|url=https://spikes.insideathletics.com.au/product/7mm-christmas-tree-spikes/|title=Christmas Tree Spikes|date=2020-05-19|work=Inside Athletics|access-date=2020-05-19|language=en-US}}</ref> Lastly, there are Tartan spikes that are dull that are most commonly used for rubber tracks.
