After their numerous collaborations with sneaker stores across the globe, the Reebok Pump rounds out its 25th anniversary celebrations with the release of two OG colorways. The historic model made its debut back in November 1989 with the revolutionary Pump technology, which used an inflatable air bladder system built into the shoe. It quickly made its way onto the feet of professional athletes and became a cultural icon. Set for release just a few days after its official anniversary, the Reebok Pump will come in two classic colorways – black and white. Both styles feature premium leather uppers with grey accents and the orange Pump component. The "OG Pack" it set to release on Black Friday, November 28 and will be available at select Reebok retailers worldwide.
