I wear FitFlops almost exclusively. The problem is size-consistency. I wear 9-1/2, so I must guess whether to get a 9 or 10 in each style. I guessed size 10 for this style, but it had an unexpected additional problem. It's too tall, meaning too far from sole to top. Gripping the sole with one's toes is the only way to keep from walking out them. Essentially, an impossible-to-wear pair of shoes. Size 9 cost $10 more, so I decided to not aggravate myself by giving it a try. If you have a really high arch, this might be just the style for you. For the rest of us, forget it.
