TECHNOLOGY:

 

Zero Drop™ Platform: Places your heel and forefoot the same distance from the ground to encourage low-impact running technique, respects the natural alignment of the body and strengthens calf muscles that are weakened by raised heels.

 

FootShape™ Toe Box: Allows your toes to spread out comfortably and naturally and for the big toe to reduce pronation. The result is improved stability and increased propulsion for optimal running performance.

 

A-BOUND: Made from recycled materials, this exclusive layer located directly under the foot reduces shocks from hard ground and returns energy with each stride. It feels like having a bouncing ball under the foot!

 

InnerFlex™: Internal grooves in the midsole. By increasing multi-dimensional flexibility they allow the feet to be more responsive and improve speed and performance. This technology also reduces the weight of the shoe for a better running experience.

 

FootPod™: This exclusive outsole respects the morphology of the human foot and helps it to move naturally for optimised flexion, enhanced support and improved balance.

 

NRS: This exclusive system combines an outsole and midsole adapted to the morphology of the metatarsal with the fully cushioned Zero Drop ™ platform and the FootShape™ toe box to let you run the most naturally possible.

 

COMPOSITION:

 

EVA: The moulded EVA insert provides lightweight cushioning and stability.
