I have never found a better fleece sheepskin slipper...The bottoms lasts forever..the heels don't slouch down...The slipper, in general lasts forever and is actually more like a soft shoe..So comfy right out of the box..I purchase them in two sizes..One in a mans 9 wide so it will fit my super thick socks...and a womens 8 to fit thin or no socks...They are pricey but are worth it...absolutely wonderful...and stong enough to wear to the store or to run errands...LOVE LOVE LOVE THEM
