The Reebok Pump Supreme Ultraknit, a running shoe using the Pump technology, features a stretch fit ultraknit mid-cut shape in a navy colorway, with ankle support for a comfortable fit. The IMEVA midsole brings extra cushioning while the carbon rubber in the forefoot fortifies the rubber outsole that incorporates a TPU plate for stability. Through the “Pump” you can always adjust the fit perfectly to the shape of your foot.
