The adidas Ultra Boost combines state of the art technology with a timeless design. The “Utility Black” colorway follows in those footsteps by giving it a subtle look. The shoe comes with a Primeknit upper material
with a contrast knitted into the core black upper, ensuring maximum flexibility, reducing the risk of foot damage through friction. Talking about the Ultra Boost, 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, temperature has no impact on the Boost and its flexibility, which means, you can run all year around with the same running experience. Finishing up, the adidas Ultra Boost gives maximum heel-stability up to the Achilles, while the sock-like feeling of the shoes and its featherweight make the shoe become one with the runner. Pick up to a size bigger, since the shoe is running a bit small.
