I bought these because I have a foot plantar problem from wearing shoes with no arch support! My wife wears the Fitflops Sandals and after years of wearing a boot to bed because of the plantar issue she now wears these Fitflops Sandals and her problem has not come back. The combination of night boot and Fitflops cured her issue.

I wear a 10.5 size, I purchased size 11 and they were so small, they were painful. I then purchased the size 12 which is a little loose, but satisfactory. These seem to run very small!
