Speed – build for speed! Developed for quick training runs or race day, the Speed has come out on top among its peers in several performance reviews, among them Runner’s World 2017 Fall Shoe Guide, who deemed it ”the lightest and most flexible shoe in this guide”. The Speed8 midsole is powered with Recoil PLUS, providing an incredible 20% higher energy return, making it Salmings most reactive compound to date and an incredible update from the Speed7 version! To enhance the comfort and cushioning properties of the heel impact zone - a SoftFOAM™ area has been added - a heel insert area that has 70% better shock absorbing properties than standard EVA. The outsole features a durable lightweight rubber and a dark graphic patched pattern on the upper glows in a rainbow of colors when a car’s headlights hit them – run safe run fast!
