The adidas Ultraboost Uncaged combines state of the art technology with a timeless design. This stripped down model with a white colorway follows in those footsteps by giving it a subtle look. The shoe comes with a trace cargo / green Primeknit upper with integrated support, to ensure maximum flexibility, reducing the risk of foot damage through friction. Talking about the Ultraboost, you can`t get around highlighting the sole, the soul of the shoe so to speak, consisting of 3,000 thermoplastic polyurethane energy capsules. With every step, the Boost sole pushes back the energy, applied through the weight of the runner. Winter or summer, the temperature has no impact on the Boost and its flexibility, which means, you can run all year round with the same running experience. Between the heel and the forefoot, you can find a Torsion System for a stable ride. Finishing up, the adidas Ultraboost gives maximum heel-stability up to the Achilles, while the sock-fit upper enables a snug fit.
