I checked and double checked the sizing and ordered what I thought was right. No. Too small. And the hole was so small I couldn't even put my foot in it to see if I could PERHAPS get it to work. I bought them to wear in the shower so I don't fall back in there. I'm so frustrated that they don't work. I bought a pair of grooved rubber soled "beach shoes" and they work exactly how I need them to. Not as pretty as these, but who will see them but me?
