While these shoes are very attractive I was disappointed with the support provided by the shoe. There was minimal to no arch support and the sole is very very flexible. I tried these shoes for both Zumba and a Spin class and wasn't pleased with their performance for either. I left with knee pain that I haven't experienced in my five years of dance fitness. While these shoes may be adequate for weight lifting or similar activities I would not recommend them for anything that even hints at impact.
