Description of NIKE Zoom Rival Track Spike907566 003 Men's Shoes for Athletic
Phylon sole. Style#: 907566-002. Phylon lightweight foam for responsive cushioning. Pebax midfoot plate with five removable spikes for propulsion. Includes 1/4" pyramid spikes and a wrench. Track athletes training for the 800- to 5,000-meter don't need much equipment.
As a result of my tests, I determined that the traction on these shoes was subpar which is a big downside for a track spike.The only pro is the sleek design, but that's not enough to make up for the lack of performance..
Although the shoes may be good, why waste money without quality spikes. My son has put spikes in many shoes with great success. The spikes on them were so soft they crossed over and then you couldn't take them out of the shoe to try and smooth them out. The mandrel is actually broken in the wrench. Very dissatisfied with this purchase.
