The Reebok Pump is a line of athletic shoes that was extremely popular in the early 1990s. It was the first shoe to have an internal inflation mechanism that regulated a unique fitting cushion in the upper.
After the success of the basketball shoe, Reebok designed pump shoes for football, tennis, and track. Some models used a standard CO2 cylinder instead of the pump for weight considerations.
Dominique Wilkins wore the Reebok Pump original from 1989 on. The original Pump is now known as the Pump Bringback.
CCM briefly offered a hockey skate with The Pump in it circa 1995, however it was derided for its poor durability. The Pump did not make a return to hockey until 2006, when Reebok (now the owner of CCM) brought out the 9K, 7K and 5K ice, goalie, and 8K inline model which used The Pump as a customizable heel-fit mechanism
World Wrestling Entertainment wrestler John Cena wore Reebok Pumps as part of his old-school, hip hop gimmick. He would often stop to "pump up" when he was gaining momentum towards the end of matches.
There were two competitors for the Reebok Pumps. One was the LA Gear Regulators and the Nike Air Pressure. Later on, Nike would use a similar inflation mechanism in their "Shox" models available as basketball or cross-training sneakers.
Pump technology is making a small comeback. For instance, DC Shoe Company introduced a series of snowboarding boots with Pump-style liners. 2006 / 2007 models include the Judge, Graphix and Ghost boots. Reebok has also brought back this line, with current shoes being the ATR and The Pump 2.0, which automatically pump as the user walks. They also have the original manually operated pump mechanism shoe available. Outside of athletic shoes, Reebok continues to sell the resurrected the pump for use in its high-end hockey skates (sold under the "Rbk Hockey" banner) to improve heel lock and fill the negative space inside of the skate. Popular NHL hockey stars Sidney Crosby and Alexei Kovalev both wear Reebok skates featuring the pump.
