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

Slick road bike tires that are pumped to close to maximum pressure are not ‘bouncy’ in that sense and you can feel everything underneath you.

100x more so when you are on a low rider recumbent bike with said tires.
