Airia Raw is a racing flat with a narrow focus. Max speed at road races of about 5-10 kilometer. This has helped us in optimizing every aspect we know of. Specifically Weight, Comfort, Sole Rebound and our patented proprietary speed hack which we call BioSpeed.

Airia BioSpeed is an inward drop that helps the foot to go faster from landing to takeoff in the stride. This drop alone has in prototypes given consistent average faster race times.
