I. Love. Them. I've never had a "nice" pair of slippers before. I've always worn various terry or velour slip ons which are ok. I'm getting older and my feet are more tired. I was needing a slipper with more support and one that didn't slip off so easily. These fit the bill. The back of the slipper comes up about an inch to keep your heel warm and make the slipper more stable. The arch support is as good as many tennis shoes. The soles are quiet and slip resistant. I wear a 7 medium and the size 7 fit perfectly. I would suggest sizing up if you have wide feet or you wear a half size.
