These snuggie slippers are not a replacement for a good pair of slippers to wear around the house all the time, but they are so comfy and warm. They run just a bit large, so do not order up one size.  I wear 8-1/2 to 9, but I wanted to wear socks with these, so I ordered the 10-11 and they are way too big, but I still love them.  I haven't tried to throw them in the wash yet, but if that is possible and they survive, I am going to be even more in love with these. I have a great pair of slippers that are a little more substantial, but these are perfect for lounging.
