I have had a very hard time finding an athletic shoe with an adequate arch support. I have fallen arches, and RA, so I'm a challenge. I have Oofo flip flops, and they have been very good to my feet. Some reviewers said these have a big toe box, and the Oofo people said that all their footwear had the same foot bed. THAT'S what sold me. We bit the bullet and spent way more than planned. I wear a 7 1/2, so I ordered an 8. The fabric the body of the shoe is made of is stretchy and not confining. My foot slid right into place and when I stood up, that same wonderful foot bed hugged the bottom of my arch! YaY!But the little toe on my left foot is rubbing. The right one isn't. My husband measured and the left toe box is 1/8 inch narrower than the right. Just enough to matter. The right one has enough room. If I got a bigger size, the whole of both shoes would be too big. I'm hoping the company will exchange for another pair because the rest of the shoe is heaven. They also look good.To sum it up, I do recommend this shoe if you're looking for a high, yet comfortable arch support. I also recommend getting a half size bigger.
