They are really comfortable. A little on the edgy side which is where I am not sure its a good thing or a bad thing.  Either way I am keeping them and hope they will live up to the challenge of lasting through a whole evening with dancing.

Adding comment 5/19/13 - I wore these for 8 hours and danced in them without problems all night. Very, very comfortable; very stable (no wobbling, no slipping). THis was definitely money well spent.
