The On Cloud X 4 is a light, flexible training shoe built for gym work, short runs and everyday wear. Its X-shaped Speedboard and Helion superfoam midsole give a soft landing with a quick toe-off, while a midfoot cage and padded heel hold the foot during side-to-side moves. It is less cushioned and less plated than On's running-focused shoes, so it suits mixed training better than long-distance running. Owners like the light, breathable feel and secure heel; some find the fit narrow and the outsole grip modest on smooth gym floors.

The On Cloud X 4 is a flexible training shoe built for workouts. It is designed for comfort and versatility across different kinds of training.
The midsole uses Helion™ superfoam for soft landings and powerful take-offs. An X-shaped Speedboard® in the forefoot adds flex. A midfoot cage gives extra support and lateral stability, and the heel holds the foot well during multidirectional movements.
The upper is breathable mesh, with plush materials in the heel and tongue. The rubber outsole provides traction during side-to-side movements.
