My dad traded out the slide on mule slippers for these more shoe style slippers, because the mules slid off the backs of his heels a little too easily while he was walking. He really likes these, comfortable, good soles, wear around the house or in the yard. The do not have arch support so they are not meant for walking around a lot. The "roof" of the slipper has a nice elastic that does a high arch like his very good to get in and out, and he says they are comfortable. They stay on your feet with or without socks.
