Long miles ask a lot of a shoe, and On's Cloudboom Max answers by stacking 40 mm of dual Helion HF supercritical foam under the heel. Engineered mesh wraps your foot over a roomy toe box that fits true to size, and an internal heel counter keeps the rear locked down. The 8 mm drop and forefoot rocker roll you smoothly through every push-off. It's the shoe you'll want on race day when you're chasing a four-to-six-hour marathon finish.
