As you may already be aware, the Reebok Pump is celebrating a big birthday this year. The innovative Pump technology was first introduced in 1989 and not only made a big splash at the time, but left a legacy of fond memories in the minds of those who were around to appreciate the first go-around of Pump sneakers. To celebrate the Pump’s 20th birthday, Reebok will be teaming up with 20 different sneaker shops from all over the world, allowing each to bring their own vision of the Pump to life. We have already given you some sneak peeks at a couple of the upcoming collab editions of the OG Pump, but now we get a look at the entire list of contributors, as well as a video showing some of the Pump20 collaborators discussing their thoughts on the project. Keep reading for a full breakdown of all the shops that will be involved with the upcoming collection, and stay tuned on November 19th for the official unveiling of all 20 designs.
