On is a brand with a clear identity and spirit. It focuses on CloudTec tech and giving a lively, springy feel underfoot. The line has training and racing models as well as daily run shoes. They differ in cushion and use. In this piece, I show which On shoes fit best for each task, from easy runs to fast workouts and races.
Traditionally, it is worth starting with a division of shoes depending on the surface you plan to run on:
- Training shoes for hard surfaces are ideal for everyday training when safety is your top priority.
- Racing and fast training shoes are best for competitions and very fast training sessions when dynamics matter most.
- Trail running shoes are best for running on difficult terrain in forests and on mountain trails. These shoes are designed for grip and durability in difficult conditions.

On Cloudmonster 3 Hyper
The Cloudmonster 3 Hyper is a high-performance training shoe for long-distance runners looking for maximum protection against impact and high performance in a single shoe. It is not, however, a typical soft model designed for easy running. The foam blend used in the sole, including responsive Hyper Foam, gives it a dynamic character and allows it to be used during faster workouts as well. The Cloudmonster 3 Hyper thus combines the comfort needed for long runs with a dynamic roll that comes in handy when you want to run a little faster.

On Cloudmonster 3
One of the most massive shoes in On’s lineup—and one of the most comfortable. Its construction incorporates large “cells” from the Cloud system and a polypropylene Speedboard plate, which adds a touch of stiffness and performance. However, performance isn’t its greatest strength. This shoe stands out for its exceptionally high level of cushioning and softness, making it the ideal choice for heavier runners and those looking for a shoe to tackle running routes comfortably and with poise.

The cushion is top grade. It works best during long, easy training sessions. It is also well-suited for casual running. It is a good pick for heavier runners. Runners who want top comfort and a slow pace on trail runs will also like it.

It is perfect for runners weighing up to about 90 kg. Similar in construction to the Cloudeclipse, with a row of diagonal “mesh” panels, it makes for a comfortable ride during both easy and faster runs.

It is distinguished by solid cushioning provided by a midsole made in classic Cloud technology with a Speedboard plate made of TPU. This shoe is especially recommended for runners weighing around 80 kilograms. Thanks to its attractive price and satisfactory parameters, it is also an interesting option for those who are just starting their adventure with running.

The Cloudrunner is for people looking for their first “serious” running shoes with stability. It’s a model with cushioning comparable to the Cloudswift and Cloudgo, but it offers more stability. It’s mainly for overpronators who want support and stability. Stability is ensured by increased heel support, which means that, like the Cloudflyer, it can also be used by people with neutral feet. It is the optimal choice in terms of softness for people weighing up to about 80 kilograms.

- Drop: 10mm

It’s one of the simpler looks in the On line. It has less foam but more spring and road feel. The nylon fiber Speedboard plate with a glass fiber mix is behind this lively feel. Those who want a lively, slightly “raw” shoe will be happy. It’s a clear pick for runners who want a quick midsole and comfort.
