The UltraBOOST 1.0 Retro ‘OG’ 2018 reintroduces the original release of adidas' flagship runner only after a short span of three years. This iconic shoe preserves its distinctive characteristics, such as a black and grey Primeknit upper that is supplemented by a solid black TPU cage and an eye-catching purple heel counter. The comfort of this shoe is provided by a full-length Boost midsole, which is further fortified by a Continental rubber outsole to enhance its durability and performance.
