The trainer is designed for both sprinting and also long distance running, and as the sole of the shoe has been designed and created by tyre specialists Continental AG, the grip and stability of the shoe is perfect for running through snow and ice!
Ultimate Energy Return
Ultra BOOST contains 20 percent more BOOST* which performs consistently in any conditions, for countless kilometers; season after season. Using thousands of unique energy capsules, BOOST technology returns energy conventional EVA midsoles lose. BOOST provides support and guidance through a runner’s gait without compromising the energy needed to experience your greatest run ever.
Energy Harnessed
Ultra BOOST features an innovative Stretch Web outsole that adapts and moves with the foot. The perforated elastic design harnesses the energy of BOOST without restricting any of its qualities to deliver an unrivalled energized ride.
Ultra BOOST also contains a new dual-density TORSION® SYSTEM, embedded into the shoe’s base. This allows more independent movement between heel and forefoot for superior stability.
Adaptable Comfort
Through cutting edge research, the adidas Innovation Team (aIT) has learned that a runner’s foot can expand up to 10 mm or more in width during running. When this expansion is restrained it can cause severe discomfort, friction and the leading injury in running, blisters. Unlike other fit technologies that don’t allow the foot to stretch naturally, Ultra BOOST uses adidas Primeknit to allow the natural expansion of any foot shape. adidas Primeknit is forgiving, yet snug, fully adjusting to the foot as it moves. This leads to improved comfort and support, minimizing the risk of chafing and blistering.
Superior Support
Ultra BOOST features an entirely new heel construction that frees the natural movement of the Achilles tendon. A carefully tuned external heel counter cradles the foot and adapts to the high extension of the Achilles. Furthermore, a new featherweight sock liner adapts to a runner’s natural foot form, for a custom and comfortable fit.
