This is my fourth pair of this slipper and I will never own another kind! I'm a stay at home mom so I live in them, I hate to take them off. I wear a 9 1/2 or 10 and the tens fit perfectly, just give them a day to mold to your foot. It feels like they are custom made just for me! Soft, warm (but comfortable for all year), this is what you want on your foot after a long day or just to lounge around. The sole is non slip and sturdy, not even stepping on a Lego will faze you! Try a pair and you will see, these are perfection!
