To the average consumer, Nike's Flyknit tech is simply a knitted shoe. And while that's fundamentally true, the innovative, stylish tech is actually a lot more complicated than some may realize, and Nike's still improving it to this very day.

Matthew Kish of Portland Business Journal found that Nike filed four new patents related to knitted footwear today, bringing its total number of Flyknit patents to more than — wait for it — 500, which should give you a better idea of just how complex Flyknit really is.

It's not immediately clear what these new filings entail, but this is already enough to get us excited for whatever's coming next. Keep it locked here to find out what Nike has planned.
