Evolved Rocker2
The Evolved Rocker2 technology is based on 10 years of research and development, which has allowed us to create our most efficient racing rocker to date. With the ER2, we apply our advanced understanding of biomechanics principles to promote a more dynamic running posture, while reducing heel impacts and improving running efficiency. Simply put, you can run faster, longer, and with less energy.

Kinetic Light Foam
The lightest and most responsive foam in the range. Enhancing the properties of high-rebound foam (KINETIC FOAM), this new version offers even more rebound in an even lighter format. Flexible, light, and responsive, while providing the durability of robust EVA.

Speed Traction
Specifically designed to gain weight, the Speed Traction is the lightest in the range. The strategic construction of the outsole allows for a direct and efficient power transfer on the road by focusing on forefoot traction. Lighter, it allows you to run faster and longer.
