I sooo wanted these shoes to work!.. So much so, that I ended up buying two pairs - the first pair was too small, but by the time I figured it out I'd already worn them, so could not return. I bought a second pair, which fit decently. I still believe, though, that half sizes are needed badly.

That being said, I've been wearing these shoes for four months, for Zumba classes, 2-4 times a week. I was very pleased with them in the beginning - they're light, flexible, and the sole allows twisting and turning on wooden floors with ease. In the long run though I developed knee pain. I love Zumba so much that I didn't want to give up; first I bought athletic socks, then a knee support, then insoles... Nothing worked, the pain became increasingly severe. I got to the point where I wasn't able to go through 1-hour class. The biggest problem with these shoes is that they completely lack any kind of support: no arch support, no footbed support, and the worst of all - no lateral support. I am really disappointed, they look cute and they're so lightweight, but in the end I will have to just throw them away.
