Im a little surprised by how happy I am with these sandals. I needed a pair of flip flops for a trip that were versatile. I could walk around extensively in them, shower in them, and wear socks with them when needed (Im aware thats a fashion faux pas, but its to Nepal and fashion isn't a priority). Turns out these sandals are adorable. Sporty if I want them to be, feminine if I want that. Just depends on how I dress. Extremely comfortable. I have narrow feet and they fit perfectly. A lot of flip flops have excessive flop because they are too wide for me. The plus side is the width has adjustable Velcro straps so I can widen when I put on socks (or if you have wider feet). I hemmed and hawed over the size. I usually wear a 9. But depending on shoe, can vary from 8.5-10. I opted to go with the 39 and it turned out to be a perfect fit.
