These
slippers are very soft, microfiber-like material, and VERY cute. The sole was stiff when I first tried it on, but has gotten comfortable after a week or so. I purchased the XL, which is supposed to fit size 11.5 to 12.5. I normally wear a 12, and the
slipper feels a little short to me. It's probably closer to a size 11. Because the fabric is so soft, my feet tend to
slide around in them more than I like. I'm careful when I go down stairs, because it feels like they could fall off. I would probably not recommend them for an older person prone to falling.
