Interchangeable Footwear

The one concept that comes to mind was the F-50 tuneit. I actually had the system back in highschool.

It came with a couple of different uppers (Different materials, colors), insoles (stability, speed, power), and studs (soft, hard, firm ground). The idea was that you could mix and match the parts to get your custom feel. One flaw was that the studs kept unscrewing, but nothing a bit of loctite didn’t fix.
