About 80% of my shoes are Skechers because I'm obsessed with how comfortable their memory foam shoes are. These yoga flip-flops are no different, and they are super cute to boot. I bought the grey, though it was a toss-up between them and the black! However, much like Skechers' Goga Lagoon Flip-Flops (which also do not come in half-sizes), these shoes run big. I wear either a 7.5 or an 8 depending on design, but I had to send back the 8's I ordered and exchange them for 7's. The 7's fit me perfectly, despite the fact that I have pretty wide feet. I highly recommend going smaller, especially if you are a half-size in shoes.
