Interdigital spacers reduce toe friction during extended use

Built for marathons, this is the shoe that's race day ready, ultra-responsive and ultra-cushioned.

An innovative Bounceboard, made using ultra-responsive Helion HF hyper foam, helps propel you forward with power. A removable layer of plush cushioning helps maximise energy return for a bouncy underfoot feel - all whilst abiding by stack height regulations. A cushioned ride that's perfect for long races.

A stiff, spoon-shaped Speedboard works like a spring, absorbing energy and transferring it into the forefoot for powerful take-off's. A strategically placed CloudTec element helps create a faster, smoother roll-through feel which helps increase running efficiency.

An ultralight and breathable upper, made from one-piece, semi-transparent materials that help reduce overheating. The cage-like construction locks down the midfoot, giving you a more secure and race-ready fit.
