The Blue nitrile wears significantly less than the wedgetop (which I'm assuming you're referring to, right? the Brown stuff with criss crossed waffle-esque treading?), assuming you install it right. The reason ours doesn't wear nearly as much as others is how we attach it: rivets. When the tread is riveted at several points, it can flex and move, rather than immediately wearing as it would were it glued on it's entirety.
