Eli5: Is there a reason roller skates and roller blades don’t have spring shocks?

Question

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?

Answer 1

Because you have knees. Spring shocks on your feet means you’re wearing Moon Shoes. Sure, it absorbs the shock, but it also makes you clumsy as hell.
