Market Crash  

It's the simple adage, what goes up must come down. For the last few years sneakers have been trending up at a crazy rate, it can't last forever and eventually once the public gets over-saturated with a million colorways of shoes that originally released in three they'll move on to some other "limited" experience they crave to impress their friends. Would this happen regardless of a brands release strategy? Likely. Times are always changing but at this rate it's bound to happen sooner than later.
