"Men's On® Cloudboom Max: If you're chasing a fast marathon or pushing for a personal best, the Men's On Cloudboom Max is a max-cushion running shoe built to keep you moving efficiently over long distances. It's a neutral shoe that pairs serious cushioning with a propulsive feel, so you get the comfort you need for 20-plus miles without the sluggish ride that sometimes comes with high-stack footwear. Dedicated distance runners and marathoners looking for a fast, efficient ride will find a lot to like here.The Cloudboom Max runs on a dual-layer Helion™ HF foam midsole that absorbs impact and returns energy with each stride. A glass fiber-infused Speedboard® sits inside the midsole, stiffening the platform and snapping you through toe-off so transitions feel quick and purposeful. CloudTec® pods underfoot soften landings and help keep the ride feeling light as the miles add up. The lightweight mesh upper moves with your foot and keeps airflow going through the upper, which matters when you're deep into a long run. At 10.4 ounces with a 4mm heel-to-toe drop, it sits in a sweet spot between cushioned comfort and a low, connected feel underfoot.Why Our Fit Experts Love This Shoe""I put these on for a long road run and noticed right away how cushioned they feel without making the shoe feel heavy or slow. The Speedboard® really does push you through each step - by mile 18 my legs were tired but the shoe was still doing its job. If you're training for a marathon and want something that holds up late in the run, these are worth a serious look."" - Dave, Road Runner Sports Fit Expert, San Diego, CAWho It's Best ForIf you're a neutral runner who logs serious miles and wants a road running shoe that cushions hard without slowing you down, the Cloudboom Max is worth considering.
