Adidas UltraBoost

When Adidas launched the UltraBoost in 2015, it didn't just release a running shoe — it redefined what a performance sneaker could be. At its heart is the revolutionary Boost™ midsole technology: thousands of thermoplastic polyurethane (TPU) capsules fused together to create a foam that returns energy with every footstrike, never getting harder in the cold or softer in the heat. The Primeknit upper is constructed from a single piece of seamlessly engineered yarn, adapting to the natural expansion and movement of the foot during a run. The sock-like fit eliminates pressure points and wraps the foot in a sensation of almost weightless containment. A Stretchweb outsole with Continental™ rubber provides exceptional grip on wet and dry roads. The UltraBoost has since become one of the best-selling performance lifestyle sneakers in history — as iconic on the streets as on the track.
