The Athletics Spikes Needle 7mm offer a slightly longer needle spike for sprinters and short-distance runners who need a touch more grip on the track. The needle profile delivers clean, precise penetration into the track surface for efficient energy transfer and powerful acceleration out of the blocks. At 7mm, they suit a wide range of synthetic track surfaces and sprint events. Always check your competition's spike regulations to confirm needle spikes and the 7mm length are permitted at your venue.
