U.P. Pyramid Spikes 15mm

Replacement spikes for use on cross country.  15mm is the longest length available for cross country running and is perfect for very muddy terrain. If there's a lot of rain or if you'll be running after other teams / age groups have run the same course and dug it up nicely for you, then 15mm will be ideal. For mixed terrain 12 mm will be better and for dry courses 9mm will work best.
