Not comfortable at ALL!  Soles are super stiff which makes them extremely difficult to walk in. Its like walking in 2 cardboard boxes. The opening is very narrow so it is hard to get your foot into (and I have very narrow skinny feet).  Plus when I tried to return, the seller took five dollars off for shipping even though the product advertised free shipping is included. Obviously not since they only want to refund a portion of the money. Dont bother wasting your money on these uncomfortable cheaply made boots from an apparently dishonest company
