Regent Track & Field Running Replacement 9mm Grass Spikes - 12 Pack

Packet of 12 spikes (9mm) for track and field shoes.

This is the maximum length spike that is allowable by the IAAF in any event bar High Jump & Javelin where the maximum is 12mm, however most stadiums will in fact limit the length of spikes in competition & training to 7mm to lower the wear of the track surface.

Recommended for any distance event training on grass and for racing in handicapped grass track meets. It is recommended to avoid using these spikes in training on synthetic tracks to avoid suspension from competition when the stadium maximum is 7mm.
