Your long runs deserve a shoe that's built for them. The on Cloudmonster 3 Hyper takes everything runners love about the Cloudmonster platform and pushes it further—a taller stack height, a Pebax midsole pulled straight from On’s race-day supershoes and CloudTec cushioning tuned specifically for power and energy return. If you're training for a marathon, stacking back-to-back long runs or putting in the kind of miles that demand real cushioning without sacrificing pace, this is the shoe for you. Details Upper: A recycled polyester engineered mesh keeps things light and breathable over long efforts. The fit is secure and structured, with an engineered heel construction that locks your foot in place. It holds secure without squeezing, so comfort doesn't enter the conversation midway through your run. Midsole: A full-length Helion HF top midsole is the same responsive foam On uses in their race day supershoes—delivering serious cushioning and high energy return underfoot. This isn't just plush cushioning for cushioning's sake. The foam actively returns energy with every stride, so your legs feel fresher longer. CloudTec pods are tuned specifically for power and energy return, working with the Pebax midsole to keep the ride lively deep into long runs. Outsole: The forward-rolling geometry and CloudTec bottom unit support natural momentum through each stride. The rubber outsole offers solid traction and durability on roads.
