adidas Adizero Sub 2 Core Black

Built to break the two-hour marathon barrier, these running shoes were designed to be worn by elite athletes only on race day, not for training runs. The ultra-light shoes have a breathable air mesh upper that locks down for an optimal fit, and a Continental Rubber outsole that grips the road rain or shine. Boost Light offers the same energy return as Boost with less weight for improved running economy.
