I have worn these boots for hours and they are comfortable to walk in.  *Note - at first I ordered the Lala-02 boots but actually ended up buying the Auto-02 boots instead - I'm very happy with the Auto-02 boots since they have zippers and have slimmer ankles.  The Lala-02 boots have much wider ankles so I would recommend the Auto-02 boots for a person with thin ankles like myself.  I would definitely buy the Auto-02 boots again!
