HYPE THE BEAST. What do you get if you combine extreme CloudTec® with Helion™ HF hyper foam? Maximum cushioning with a kick. The On Cloudmonster Hyper has a dual foam midsole that maximizes cushioning, while Helion™ HF in the forefoot absorbs impact for a rebound that will energize every stride. It's the same foam On use in our top racing models like Cloudboom Echo 3.UPPER Microfiber (made with recycled polyester) delivers breathability and seamlessly molds around the foot to create a personalized fit. High-grip laces woven with silicone and reworked eyestays keep you locked in place – even during those powerful take-offs. MIDSOLE Deliberately removed the Speedboard® to encourage faster post-training recovery and to lessen the weight. Helion™ HF hyper foam acts as a bounce board below your foot and propels you forward. OUTSOLE Grip rubber compound with enhanced traction pattern. HEEL-TOE DROP: 6 mm (35-29) WEIGHT: 265 g | 9.3 oz Please note: we find this style to fit a half size big. Consider this when ordering.
