This a nice shoe with the Vionic sole. My Vionic flip flops are sz 6. I ordered this in both sz 6 &7 because I didn't know how it would fit being it's a covered shoe. The sz 6 fit best but on both my big toe keep catching the top of the shoe. I had to send them both back. It was a really nice shoe at a good price. The toe box was just to low for me and I think I have average size toes.
