Still fairly lightweight middle distance running spikes will have more padding at the heel for greater cushioning over an 800 to 1500 metre distance. They're less rigid than sprinting spikes and the spike plate is not as far forward on the toe allowing for a more moderate speed.
Best suited for events from 1500 metres to 10,000 metres, these running spikes provide the best cushioning while still maintaining a lightweight feel. They also do not feature the same aggressive spike plate as some of the shorter distance spikes.
Designed to take on more force over a longer period of time they're made from more durable, but heavier, materials. Sometimes middle and long distance spikes are grouped together.
With slightly more cushioning than your typical track spike, these are developed for running on grass in cross-country events. Typically used with longer spike pins, these are designed with more ankle support and a more secure fit for uneven terrain.
