NIKE AIR PRESSURE
It all starts in 1989 when Nike set its sights on having custom fit for its consumer with the use of air chambers located in the ankle support. An inflatable hand pump device was used to pump air, the more air you pumped, the tighter the fit! The shoe also featured a valve on the back to release air pressure hence the name from the shoe. Unfortunately, Nike Air Pressure were only produced for one year.
