The Nike Zoom Rival Sprint is made for those who want to go fast. Designed for propulsion, this spike will carry you out of the blocks and to the finish line at your top speed. This shoe has it all—it’s breathable, durable and most importantly, affordable. The upper and midsole provide efficient support to keep your foot locked in without weighing you down. The spike plate design reacts to the rubber track to give you power in every quick step. Details Upper: The reinforced upper provides key containment thanks to the supportive midfoot band and premium notched laces. The toe cap area is roomy, providing extra comfort with a sock-like fit. Midsole: An updated ¾ length Pebax plate gives you power and drive on the track. Phylon EVA foam creates a slightly cushioned but appropriately sturdy feel underfoot. Outsole: The spike plate gives you the traction and confidence to reach top speeds. The spikes themselves are made of ceramic aluminum for even more durability. The heel has both rubber and foam, to give you a strong footstrike and post-race braking.
