How does the Pump Romulus work?
Created by NASA and MIT-trained engineers, the Pump Romulus provides a custom fit by surrounding the foot with an automatic, form fitting air chamber. Inflating the chamber causes the shoe to conform to the exact shape of the athletes foot. A large volume Pump actuator is located inside the heel of the shoe. The athlete first adjusts the dial on the shoe to their desired level, between 0 and 7. Once the dial is set, the athlete takes approximately five to ten steps and the shoe automatically inflates to their desired fit. The shoe pumps up until the air chamber is inflated enough to form a custom fit around the runners foot. This cutting-edge customization technology allows runners to simply insert their foot and go with no lacing required.
