An Elite-Level, Marathon-Ready Shoe for Every Athlete

Super shoes are becoming more and more common among elite athletes and speedier runners. But with the Cloudboom Max from On Running, the brand has created a new super shoe designed for all levels of runners, from those at the front of the pack to the more casual athletes.

The Cloudboom Max takes inspiration from other Cloudboom super shoes in On’s running shoe line, offering a propulsive and lightweight experience designed for more efficiency throughout marathons and other long-distance races. The high-stack midsole is made up of a double layer of Helion HF foam, a high-performance cushioning meant to deliver comfort and energy return even after hours of running.

Embedded within the midsole, you’ll find a unique glass fiber-infused speedboard. This speedboard adds some structure and support throughout the shoe, all while giving the Cloudboom Max the pop and efficiency that super shoes are known for. Paired with the plush yet responsive midsole foam, this plate gives each step a propulsive feel and keeps you moving forward during long runs or marathons.

When you first step into the shoe, another immediate standout is the lightweight, breathable upper. The supportive mesh material fits like a glove and adjusts to your foot’s movement, creating a secure feel that will carry you through 26.2 miles in comfort. Last but not least, the rubber outsole ensures you can enjoy everything about this unique shoe for miles and miles, aiding in the overall longevity while adding traction and grip to the shoe.

Soft, light, supportive

Decided to give this shoe a try, after alternating between the Cloudmonster 2, Cloudboom Strike, and Topo Cyclone for training and racing. The cushioned ride of the Cloudboom Max is combined with the support of the CM2 and Topo Cyclone. This will be my go to for marathons. Runs small compared to other On models. I had to exchange for 1/2 size larger.
