Designed by athletes. For athletes. The lightest shoe in the Cloudmonster family, its dual foam midsole combines max cushioning with max rebound. What do you get if you combine extreme CloudTec with Helion HF hyper foam? Maximum cushioning with a kick. A dual foam midsole maximizes cushioning, while Helion HF in the forefoot absorbs impact for a rebound that will energize every stride. The Helion HF hyper foam acts as a bounce board below your foot and propels you forward. For max energy return, max cushioning levels and hyper performance. High-grip laces woven with silicone and reworked eyestays keep you locked in place – even during those powerful take-offs. Plus, a microfiber upper (made from 85% recycled polyester) delivers breathability and seamlessly molds around the foot to create a personalized fit.
