A shoe with excellent propulsion to meet the needs of more runners.
Today, most sports shoes are designed based on male prototypes and biomechanical data.
At On, we're always striving for innovation, so we questioned this status quo.
What if we created a shoe using data collected from both men and women? And so Cloudspark was born.
What was born from this massive amount of data was a lightweight, propulsive shoe that meets the needs of more runners.

Maximum energy return
The Cloudspark is designed to reduce ground time and increase air time.
This is to create a more propulsive and comfortable ride.
This is recommended for people who tend to run with a dropped hips or who tend to overstride when trying to run fast.

Collect more runner data
We analyzed foot scan data from over 1.2 million runners to create a shape and fit that suits the most number of runners.
For example, the lightweight mesh upper is designed to fit your foot snugly while still allowing your toes to move freely.

Lightweight and comfortable to wear Ultra-lightweight materials are used in the heel, tongue and lining to maximize breathability and comfort, while the exquisite fit and support provide a comfortable ride.

A game-changing process Typically, the design process for sports shoes starts with a prototype tailored to a man's foot, but Cloudspark started with a female prototype and developed it while analysing the foot scan data of over 1.2 million runners.
