What? A shoe still has a heel counter. An air bubble "popping" or bursting wouldn't cause your heel or knee to collapse and send you tumbling down 3 flights. I think you got weak ankles or poor coordination.
@V0ltron bro I'm young my knees are fine so are my ankles ! I'm glad u have the science of the air bubble down but when an air bubble gives out at the moment of walking u may lose your balance especially since the shoes collapse I still have the shoe we can take this to myth busters if needed ! How old are u if it's anything under 20 please don't respond cause ur not old enough to have an opinion !
@V0ltron and it wasn't stairs it was a balcony I almost fell strait down to the bottom level at the Belmont Inn in Abbeville south Carolina while shooting my own yt vid !
