They slip on and off easily, yet stay put apparently because of the lining.  The soles are thick and soft, which makes walking comfortable as well as insulating against cold winter floors.  I've surprised how well they've held up, since I sometimes wear them outdoors on graveled areas of the yard.  I've been wearing them around the house since the day I got them, and will not be happy to give them up when Phoenix  warms up this spring.  But I'll be wearing them as long as I can, for sure.  I don't recall ever seeing slippers like these in the stores; most are flimsy by comparison.  I'm really pleased with this purchase.
