We don't know about the durability yet, but the show opens Friday. The guys that I bought the jazz shoe for are not complaining, which means they fit and are working well for all the dance numbers and these guys aren't dancers.
I just measured my feet and I am solidly a 7.5 in my right foot and 8 in my left foot. I ordered a 9 as recommended, but they feel really loose on me. Standing normally, my toes are almost to the end, but they feel really loose still. Also, I wish the arch had some sort of elastic so it pointed better. When I point my toes, the arch feels stiff.
