I've worn Birkenstocks for many years and usually, step into them and wear them all day. I honestly can't wear these for very long at one time, and it may not be entirely the fault of the shoe as I have osteophytes in my feet that can make any shoe uncomfortable if worn too long. They're well made, as anyone who has ever worn Birkenstocks already knows. Also had a problem with the right shoe rubbing in between the big toe and the one next to it. I love the color and the look, but really wonder how long I'll wear these given the fact that they're just not that comfortable for me.
