THE PUMP technology, according to the Reebok Archive, comprised inflatable chambers installed into the shoe that allowed the wearer to create a unique fit by either expanding or deflating the sections of the shoe around the ankle and complete foot, providing stability and support. It was invented by Bernard Rubens and introduced in 1973 as an innovative alternative to conventional shoe designs at the time. The pump was so successful that it became one of the most copied technologies of its time. In addition to being used for fit adjustment, the pump also served as a safety feature in case of a fall. If the valve was not properly closed, then air would escape from the shoe, giving the wearers enough time to take action before they got back on their feet. The Reebok Pump was such a success that other brands have adopted a similar technology over the years. Some modern athletic shoes with adjustable fit features include Nike's Air Max and Adidas' Boost. In conclusion, the Reebok Pump was a revolutionary shoe that changed the industry and helped make Bernard Rubens famous. This shoe benefited people by offering an affordable option to custom fit shoes instead of relying on one size fits all designs like they do today. In addition, the pump was a safe choice if you were prone to injuries because it gave wearers enough time to take action if they experienced a problem while walking or running.
