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?

They tried with with hiking poles a couple decades ans everyone got tennis elbow and/or arthritis in their wrists. Sometimes it’s better to just let your body absorb the shock.
