UltraBoost 4.0 'Grey Lime'

Building upon the innovative design of the previous UltraBoost silhouette, the April 2019 release of the adidas UltraBoost 4.0 'Grey Lime' is upgraded streamlined engineering. Adhering to the shape of the foot, Primeknit mesh covers the upper, supported by its distinct Three-Stripes lacing cage. Below, the Torsion system, Boost midsole and flexible outsole give and receive energy with each stride.
