On Cloudboom Max Women’s

On Cloudboom Max Women’s – Marathon Super Trainer for Every Pace

On Cloudboom Max Women’s is On’s marathon shoe, built for runners finishing in four to six hours. It brings super-shoe technology to recreational marathoners, not just front-of-pack elites.

What Makes On Cloudboom Max Women’s Different

• Dual-layer Helion™ HF foam pairs a softer PEBA top with a firmer TPEE base
• Glass fiber Speedboard® plate adds propulsion without sacrificing stability
• Wide, anatomic toe box accommodates wider feet with no heel slippage
• High sidewalls improve cornering and keep the foot planted through turns
• Lightweight engineered mesh upper delivers a secure, breathable, dialed-in fit
• Firm, stiff ride feels most efficient at slower, steady marathon paces
• Pink-to-mint gradient upper offers a distinct look for race day or training

Built for the Marathon Middle and Back of the Pack

Most carbon-plated super shoes are tuned for elite paces under three hours. Cloudboom Max targets the much larger group running four to six hours, prioritizing stability and wide-foot comfort over the bounciest possible energy return. It won’t feel as lively at faster speeds, and some testers note it runs heavier than competing super trainers.

Fit & Ride Notes

The wide, anatomic toe box suits runners who want extra room, with a secure heel lockdown. The ride feels smoothest at easy-to-moderate paces rather than uptempo efforts.
