Comfortable, and the soles on these slippers are as tough as an outdoor shoe. The hook & loop flap gives the uppers a wide range of adjustment. I wear these out to the garage and mailbox in all weather and they keep my feet warm and dry. They fold almost as flat as the sole thickness so traveling with them takes minimal luggage space. I bought these in December 2017, have worn them daily, and they still look brand new. They are truly machine washable which was the primary reason I bought them. I was tired of throwing out expensive slippers once the insole got smelly after only a few months.

Completely satisfied.
