Best purchase of the year. Purchased a half size larger and was worried they would be too big, but fit perfectly. Had purchased other slippers for less money and they were as cheaply made as the price. These slippers are well worth the cost, comfortable, warm, easy on/off. Have worn them outside in up-north winter weather-nice thick sole but still flexible. Like that the backs are higher to keep your heels warm. I will definetly purchse these again when a new pair is needed, but the quality is so good, they might last forever!!!
