These running shoes were assembled at adidas' innovative SPEEDFACTORY facilities in the USA and Germany and are releasing in Tokyo. Built with insight from Tokyo runners, they're crafted specifically for the challenges of Tokyo's varied city landscape and bustling streets. Responsive Boost cushioning and state-of-the-art glueless, fused bonding give you the most direct Boost comfort and energy return ever. They enable a steady and adaptive stride via the SPEEDFACTORY Torsion bar that floats in the outsole for optimal flexibility. The knit upper features tension patches for a digitally-crafted fit, and a connected eyestay gives you all-around stability. Each shoe has an embedded NFC chip in the tongue offering authentication and a unique digital experience.
