Maximum energy return

Less ground contact. More air time. Why? A propulsive running sensation, ideal for people who run in a seated position. It's an ultra-comfortable, forward-rolling ride with a flexible Speedboard that delivers an energy return you can feel.

Data-driven design

After analyzing data from over 1.2 million foot scans, usually, the design process starts with a men's prototype. But for the Cloudspark, we flipped the switch and started with a women's prototype. From this, we created a shape and fit tailored to the needs of more runners.

Light and breathable

The heel, tongue and inner are made using ultralight materials. This ensures maximum breathability and comfort while creating a secure running sensation. The engineered mesh upper is made from 100% recycled polyester that molds to the foot, while allowing your toes to move.

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.
