I usually wear 9.5-10 in shoes but needed a 9 in these. I use them for Zumba and other exercise dance classes. They were comfortable the first time I wore them and had great stick. I love how lightweight they are-very noticeable in that way even compared with my Ryka shoes. The shoe laces are unique and really stick in place when I tighten them. But for some reason, they don't hold the knot well. so i either have to re-tie during my class or make a double knot but it's only a small annoyance. also great ventilation. the body of the shoe is somewhat soft and unstructured which I actually ended up really liking but may not be for everyone. Lastly, I think I have a little bit of a narrow foot and these were form fitting to my feet on the sides so not sure what they would be like for a wider foot. overall, happy I tried these!
