My Wife truly enjoy's this Slipper. The size 7 that she wears, is a good fit for her foot. Compared to other slip on slippers it was in her words the most comfortable slipper she has worn, without the problem of walking out of the slipper. I am assuming it's because it is a Thong style slipper. An added observation; the sole actually leaves the imprint of her foot, so ever time she puts them on her foot slides right back into where her foot is the most comfortable. Lets hope the quality will last.
