I love how comfy they are and would definitely buy the ones that you can tighten around the top of the foot. With my narrow feet, the toe strap is almost too big.
These shoes are super cute and I love them! They are comfortable and fun to walk in. I rated four stars instead of five simply because the thong straps are a little snug. I have wider feet, so this could be me, but after wearing them for an hour or so, the straps were giving me a hard time. It doesn't bother me enough to stop loving them though because they're perfect for summer!
