Altra Ego™: Thanks to a clever mix of materials combining comfort, flexibility, rebound and resistance, the Altra Ego is the holy grail of cushioning. Its close to the ground cushioning and increased responsiveness gives you unequalled sensations. Altra Ego™ is designed for those who do not want to focus on comfort over dynamism.
Altra Ego's dynamism helps you keep rhythm and pace with maximum energy return. This new innovative material has the distinction of providing a better rebound, better energy return and better durability.
Unlike EVA midsoles, Altra EGO™ gains in performance when it heats up. In comparative tests with traditional running shoe foams this new cushioning has proven incredible durability, allowing it to maintain its cushioning properties and responsiveness throughout the life of the shoe


ZERO DROP:  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.


FOOT SHAPED 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.


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.





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