This has to be the most uncomfortable shoe I have ever tried to wear. The arch is strangely shaped, positioned so that it did not align with the arch of my foot and generally wrong in every way. If you have very flat feet as I do these may not be the slippers for you. I know that they say you have to get accustomed to wearing the Orthaheel shoes - I could probably become accustomed to walking with a rock inside my shoe too, but I don't think I would want to. That's what it felt like! As for fit, the slipper was the right length and the toe area was a bit wide but still what would be classified as a medium width, but the heel was so wide it slapped up and down when I walked, slipping on and off. I couldn't send these slippers back fast enough.
