I got these shoes because my knees hurt so much wearing my typical walk/run shoes for Zumba. I have to admit that my knees still hurt a little (comes with getting old I guess), but my knee pain is reduced significantly. I read the other reviews and did order a half size larger than what I usually wear and they still fit a little snug, but I push through and after about 3 sessions they fit like a glove and comfortable. Wish I would have gotten these earlier!
