text: While I like the style of the flip flop, the sizing is too ambiguous. I'm a 7.5 and the sizes they go by are either 6.5-7.5 or 7.5-8.5. I'm certainly not an 8.5 so I figured the smaller size would be fine but the back of my foot was right on the edge. So even though I got my free prime shipping, now I have to pay to have them sent back for exchange. Not very happy.
