This cushioning material stores more energy than any other cushioning material that adidas has developed to date. It then returns almost all of the energy, so that very little energy is lost. The super-light cushioning ensures next-level speed. Between the foam material, there is a Carbon plate under the heel and EnergyRods under the forefoot that are enriched with carbon. The EnergyRods follow the anatomy of the forefoot. They return a lot of energy and offer flexibility. This allows you to experience a very energetic and reactive push-off. The Carbon plate in the heel absorbs the impact during a heel landing. Thanks to the geometry of the competition shoe, you experience a powerful transition and roll-off, allowing you to run faster with less effort. Upper To provide optimum comfort and support, the Adizero Prime X 2 Strung features the innovative Strung upper. Strung is a textile innovation that uses athlete data to dynamically tailor material to the athlete’s needs. Strung is flexible and lightweight, creating a seamless cocoon shape around the foot. Outsole The shoe's rubber outsole provides good grip and traction while running. Experience ultimate speed and agility with the adidas Adizero Prime X 2 Strung, specially designed to take your performance to new heights and let you shine on the podium.
