The Reebok Insta Pump Fury Ultraknit is a knitted version of the Reebok Insta Pump Fury. This particular colorway opts for an OG look, as Yellow, Black, Red and White take care of the model that consists of a mid-top construction, knitted bootie that can also be seen on the underlays and toe. Although the shoe is given a few updates, the classic Pump technology, carbon fiber detailing and sole cushioning remain in an effort to conserve some of the model’s classic features.
