The Ultraboost may have established itself as a fashion favorite, almost from the moment it was unleashed, but first and foremost, the Ultraboost is a performance running shoe. That means standing still isn’t an option. A new year brings an updated, reimagined version of the beloved Ultraboost design. Like all the people going through their stuff trying to decide what sparks joy, the Ultraboost is simplifying for 2019, with the 17 piece design of the original trimmed down to 4 components.
A one piece, Primeknit 360 upper sits atop a Boost cushioned midsole. The new model not only features 20% more Boost material, but is augmented by a new, energy-returning Torsion Spring system, while a 3D molded heel counter cradles the foot on impact and allows for a range of Achilles movement.
