I tired several of the boots from New Zealand and Austrailia and did not care for any of them.  They were either too hard soled or no support, like a slipper.  The Fitflop is supportive and just the right amount of cushioning.  Plus they are easy to put on and take off. I do not feel the "wobble effect" but know they are comfortable from beginning to the end of the day.  They are also very light, so your legs do not get tired.
