Track spikes made in part with recycled materials.

Break free of your personal best. These Adizero Sprintstar shoes were crafted for athletes chasing maximum velocity. Built with a synthetic upper and lined with mesh for breathability, they lock you into a rigid spike plate that maximises straight-line speed. Push off with confidence knowing an aerodynamic silhouette and synthetic sole are propelling you forward stride after stride. For track stars intent on crossing the finish line first, this is your formula for acceleration. This product features at least 20% recycled materials. By reusing materials that have already been created, we help to reduce waste and our reliance on finite resources and reduce the footprint of the products we make.
