I was thinking about this the other day…skateboards are flexible, bike tires are bouncy. Why aren’t there “performance” skates with shocks? Wouldn’t that be better for your knees?
I mentioned it in a reply, but I should have been more specific… I’m talking more about jumps. This all stemmed from people doing jumps down a flight of stairs on roller skates. It occurred to me that that must be hell on their knees.
