Regent Track & Field Running Replacement 12mm Grass Spikes - 12 Pack

Packet of 12 spikes (12mm) for track and field shoes.

These spikes when used in IAAF competition meets are only allowed in the High Jump and Javelin events.

They are however very useful for those competing in handicapped grass track events and can give additional grip to those doing sprinting training on grass surfaces. This length spike is not to be used for any distance racing on synthetic rubber surfaces.
