got these as a x-mas present for my mother. she always had a hard time finding slippers that could "stand up" as she says. other dept. stores slippers after time would flop over and you couldn't slide your feet into them quickly if needed. she also loves the sole it is durable but not boot feeling she can go outside with them, they have a great gripping sole so she is sure not to slip around. lastly TOASTY WARM!! everytime I see her she can't stop telling me how finally her feet are warm. she has even turned down her heat, which if anyone knows older people like the heat at 80 in the winter time. so thank you so much for that!! this seller was great, fast shipping, excellent product and will definitely use again!!
