The Nike Superfly Elite 2 sprinting spikes are designed for runs from 100 meters to 400 meters. These athletic shoes are secure, stable, and feature a lightweight Atomknit construction for enhanced breathability. The outsole is designed with data from hundreds of runners, resulting in increased stiffness and reduced weight. Peaks throughout the plate provide traction, giving your foot grip as you run around turns. They include eight removable stainless-steel pins to help grip the track. The notched laces provide a secure fit and help reduce the chances of the laces coming untied. These sneakers are ideal for 100m-400m sprinters and are World Athletics approved.
