What's better, shorter spikes or longer spikes? so 5mm/6mm/7mm?

Question

Are 5mm spikes or 6mm or 7mm spikes better for sprinting? which 1 is best. Also do u kno if the pyramid or pin spikes are better?

Answer 1

If you are a sprinter, I'm assuming you mean spikes for the track.  Quarters (1/4 inch or 6 mm) are good.  Pyramids or pins is kind of preference, but most people (myself included) wear pyramids.

Answer 2

1/4 inch for track spikes.

Answer 3

Though there are no set rules, meet officials at outdoor meets usually suggest 1/4 inch. Indoor, they usually suggest 3/16 and in XC, they usually say 3/8 or 1/4 inch.
