These durable slippers are uncomfortable compared to the ones I replace which are 30 years old by the way. . . These new ones are too high in the front and the heels are at the ankles. Maybe they'll be good if I wear them another 50 hours, but now they're inferior to the beloved old ones I still wear. All this to say that this is a well made, high quality shoe, just be prepared for a long break-in period.
