Didn't like them at all.  I had the pink in my Amazon cart for probably eight weeks before deciding just to go for it.  The angle of rise is very strange; the pressure, rather than being on the ball of my foot, is on the underside of the 'shafts' of my toes (whatever those are called).  Extremely painful.  The heel is stable and the shoe is beautifully made (Fluevog even has a video on their website of how this particular style is handcrafted), but I just can't manage it.  Also, the top-down view of my feet in the shoes was unappealing, though I would have dealt with that if the shoe were comfortable.
