UltraBoost 4.0 'Legend Ivy'

adidas expanded their Boost collection with the UltraBoost 4.0 'Legend Ivy' sneaker. Using the previous design as a template, this version upgrades the upper with a smoother texture. Released in April 2019, the upper consists of breathable Primeknit, caged by a Three-Stripes midfoot lacing system. Torsion and Boost technologies stabilize and cushion the flexible rubber outsole for optimal natural movement.
