According to On, after analyzing data from over 1.2 million foot scans, usually, the design process of these shoes start with a men’s prototype. However, for the Cloudspark, On Cloud flipped the switch and started with a women’s prototype. From this, the brand created a shape and fit tailored to the needs of more runners.

“Made with more runners in mind. This high-propulsion shoe is ideal for road runs – engineered for people who run in a seated position. Expect max air time and powerful take-offs,” the Cloudspark product description states.

All key features for the new On Cloudspark running shoe are as follows:

• Dual density sole with nylon blend Speedboard® for energy return you can feel
• Upper made from mesh that molds to your foot
• Light and breathable
• Diverse, data-driven design
• Engineered mesh upper made from 100% recycled polyester
• Speedboard®: light and flexible nylon-blend for max propulsion
• Reflective details help keep you visible in low light
• Cloudspark encourages short ground contact and more air time
