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?

Going in the way back machine here, Mission used to make a high end pair of skates that had shocks in the heel. All they did was add weight and not work well. Most people ended just taking them off. I have a pair laying around somewhere. Fun anecdote, but not practical
