These slippers seem to be made well with good materials, but they don't work for me. I don't know what it is about these slippers, but there's not enough support with this to hold your feet in place. My feet kept sliding to one side or the other so much that I actually get foot cramps while wearing this. It doesn't matter how much I tighten them. There's not enough support and that's dangerous because I almost fell a couple of times because my feet were moving around too much. Since then, I have washed them and gave them away as donation. They wash very well as advertised, but that's the only good thing about them.
