Asics Track & Field Grass Spikes Replacement 9mm Pins - 18 Pack

The most traditional type of spike, most notably coined as a Grass Spike. This type of spike is allowed on all surfaces in sizes up to 9mm, however some stadiums may have stricter rules and not permit the use of any spikes over 7mm.

Very effective at gaining excellent traction on most surfaces and in particular a favourite for those running on grass surfaces. 9mm spikes are generally used solely by High Jumpers & Javelin Throwers, however are also widely used by those training on grass surfaces for addition traction.
