These shoes are great! As others have suggested, the shoe runs large so I did return the size 10 for a 9 1/2. But other than that, they are super comfy and very cute for athletic sandals. I'm no longer able to wear any shoes that aren't supportive (like cute little flats, flip flops, etc.) due to flat feet so I'm super happy with these. I don't have any problem with the strap as others mentioned and I have small ankles, so they are tightened as tight as they go and they never come loose. GREAT shoe! I'll be ordering more colors in the future.
