I ordered these about a month ago.  I have owned at least 6 pairs of the yoga sling 2 sandals, which have the same yoga mat sole as these flip flops. I always fit in the sling 2 as a size 8 (even though most other brands I wear size 8.5- the sling 2 size 8 is perfect for me.  Not these flip flops, they are too small, and I am saving them for my daughter who is a size 7. The sandals appear to be sturdy and of same high quality as the sling 2s, but very disappointing they aren't of the same cut to size, and offer higher frustration.
