Women's On Cloudspark flame/black running shoes (3WE10400879)
Women's Running Shoes On Cloudspark are the perfect choice for runners looking for efficient and modern running footwear. Weighing only 235 g, they are lightweight and specially designed for runners with a neutral foot. Thanks to their construction, they perform excellently on asphalt, offering an optimal combination of comfort and dynamics.
Sole and Energy Return
The sole design in the On Cloudspark uses dual-density technology, enhanced with a Speedboard® made from a nylon blend. This element is key to providing the runner with excellent energy return, felt with every step. The Speedboard® ensures maximum acceleration due to its lightweight and flexible nature, making each push-off more dynamic.
Upper and Comfort
The technological upper of these shoes is made from high-quality mesh that adapts to the shape of the foot while providing excellent breathability and comfort. The materials used in production are lightweight and breathable, guaranteeing comfort even during long training sessions. Various design details are based on data analysis, making these shoes exceptionally refined.
Safety and Dynamics
Both safety and performance are key aspects of the Cloudspark shoes. Reflective details increase the runner's visibility in low light, while the specific shoe construction promotes a short ground contact time and more time in the air. This combination results in better support and stability during running.
Design and Drop
The design of these shoes is based on data analysis aimed at creating the best running experience. With an 8 mm drop, the Cloudspark provides a planned transition from heel to toe, reducing joint stress and supporting the natural movement of the foot. Such technical solutions demonstrate the advancement of On shoes, perfectly tailored to the demands of modern runners.
Product Details

Outsole
The durable rubber outsole guarantees excellent grip on various surfaces, both dry and wet. Strategically placed tread zones support stability and smoothness of the step, while additional abrasion resistance enhances the durability of the footwear.

Lightness and breathability
Ultralight materials used in the upper provide optimal ventilation and comfort throughout the training session. The heel, tongue, and interior of the shoe are made from breathable fabrics that not only fit the foot well but also regulate temperature, reducing the risk of overheating.

Anatomic shape
The Cloudspark project was developed based on the analysis of over 1.2 million foot scans, allowing its shape to be tailored to the natural anatomy of the female foot. The shoe's construction has been designed to provide support in key areas while leaving space for the toes, enhancing comfort and freedom of movement.
