Special Technology How the tech works: The IsoPlate foot frame wraps up the lateral forefoot to keep players contained over the footbed, helping secure the foot when going from front to back. The Formula 23 foam provides a lightweight, responsive ride and helps propel the player during side-to-side movement--think a step-back, a Euro step, a crossover or even a defensive slide. Breathable Flightwire cables on the lateral side of the upper also help contain the foot. The shoe follows a long line of innovative Jordan Brand performance systems. The guard's debut signature shoe combines a new IsoPlate foot frame and a new performance foam called Formula 23. The IsoPlate system continues a long legacy of Jordan Brand performance innovations, like Flight Plate and Eclipse Plate technology. An injected foam, the new Formula 23 is one of the most sustainable performance foams made by a NIKE, Inc. brand.
