The kneepads were purchased to facilitate our child in an apartment with quite smooth base getting into crawling. This Zeck have the saver met (on the contrary to a pair of tights, here the knobs fit anatomically nothing to the knee). Advantage of the saver: You can freely post; the disadvantage would be: they can slip - when combined with appropriate clothing but that was no problem.
I'm assuming, etc. as knee protection on rough concrete they would very quickly - the liability is clearly in the foreground.
