Boost™ features in the midsole for an exceptional, energy-returning ride. The unique cell structure of boost™ allows each capsule to store and then unleash energy, providing durable, adaptable, all-temperature performance. STRETCHWEB adapts to every runner’s foot strike by unleashing the full potential of boost™ and provides a smoother and more flexible ride.
While the TORSION SYSTEM® supports the arch and provides midfoot integrity, the FITFRAME 3D-moulded TPU helps to increase stability around the heel and enables the free motion of the Achilles tendon.
The Ultraboost features a Primeknit construction, which reduces irritation and moulds to the contours of the foot, delivering a precision fit and a secure, locked-in feel. The Continental™ rubber outsole provides superior traction in both wet and dry conditions.Features Include:
