This is my first pair of Crocs sandals and I absolutely love them. Ive been a diehard Teva fan for years, but these give my Tevas some serious competition. As far as sizing goes, I vary from a 9-10 depending on the shoes. I decided to try a 9 in these and they are perfect. Although I will say if you have really wide feet they might hang off the sides a bit. But definitely worth trying! I ordered my first pair a couple weeks ago and I just ordered my second pair today in another color.
