UltraBoost 4.0 'Carbon'

Part of a four-colorway pack that released in September 2018, the UltraBoost 4.0 'Carbon' sneaker fuses adidas’ Primeknit, Boost and Torsion technology for innovative design and performance. This 4.0 sneaker is built with an integrated Three-Stripes cage that supports its flexible Primeknit upper. The sneaker is bolstered by a Fitcounter heel and a 3D heel frame, reinforced by an energy-returning midsole for a natural feel.
