The Cloudmonster 3: On Got Everything Right This Time

Here is what happened. The Cloudmonster 1 was loved for its snappy, energetic forward roll. Then the Cloudmonster 2 came along with more cushioning but some runners felt it lost a little of that lively toe-off that made the 1 special. On heard every single piece of that feedback and the Cloudmonster 3 is the answer. They rebuilt the rocker geometry from scratch, going more aggressive to bring back that explosive roll-through feel. They added triple layer CloudTec cushioning for max energy return. And they used dual density Helion foam so the landing is soft but the toe-off still pops.

The result is the best Cloudmonster ever made. It combines what runners loved about the 1 with the protection upgrades runners needed from the 2, and it does it better than both. If you have been a Cloudmonster loyalist since 2022 or if you are brand new to the franchise, the 3 is where you start right now.

What You Get

What Makes the Cloudmonster 3 the Most Advanced Yet

Triple Layer CloudTec Cushioning

Three layers of CloudTec working together for the highest energy return in Cloudmonster history. Each layer compresses and locks in sequence, delivering a landing that absorbs impact and a toe-off that actually launches you forward.

Dual Density Helion Foam

Two densities of Helion superfoam in a single midsole. The softer layer cushions your landing. The firmer layer drives your propulsion. Together they create a ride that feels like it was tuned specifically for your foot.

Rebuilt Rocker Geometry

On went back to the drawing board on the rocker shape and made it more aggressive. The result is the smoothest, most efficient heel to toe transition in the Cloudmonster franchise. Your legs work less. Your miles feel better.

Nylon Speedboard

A nylon blend Speedboard sits between the foam layers, storing energy on landing and snapping back at toe-off for an extra pop of propulsion. It is the mechanical advantage that separates the Cloudmonster 3 from every other daily trainer in its class.

High Abrasion Rubber Outsole

Strategic rubber placement where you need it most means the Cloudmonster 3 handles the daily punishment of American road running without wearing through prematurely. Built to last 400 to 500 miles the right way.

Engineered Mesh Upper

Lightweight, breathable, and built to lock your foot in place without creating hotspots. The upper in the Cloudmonster 3 is the most refined of the franchise, designed to disappear on your foot so all you think about is the run.

Sizing

How the Cloudmonster 3 Fits

View Full Size Guide

The Cloudmonster 3 fits true to size for most runners, which is a change from the original which ran small and the 2 which ran large. Start with your normal running shoe size. If you have a wider foot or tend to swell on long runs, going up half a size gives you more room in the toebox for those big mileage days. Still not sure? Use our size guide or message the team before you order.
