I originally bought OOFO but after constant delays; first 2 days, then 30 days; then on day 29 another 30 days were added to my expected delivery. So when I saw I could get these sandals the next day I canceled OOFO and tried them. I was looking for something to wear around the house that offered more support than the regular flip flops I wore. I wear a 9 ½ so I ordered the men's 9. I found them a bit small at first, but my whole leg is very tight in them. They offer good support and felt better the longer I wore them. They meet my slipper needs at half the price of my original choice. And they are really affordable!
