Track spikes

Shoes with protruding spikes on the soles

Track spikes

Track spikes, or just spikes, are a type of footwear featuring protruding spikes on the soles 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.
