These shoes are pretty darn comfortable out of the box, and thanks to the ankle strap and wedge heel, they feel very stable! I don't feel wobbly in these at all (I'm not a heel wearer, so this is really important). I added some ball-of-foot gel cushions and it made these shoes ah-mazing!

EDIT 5/15/18: I wore these for HOURS one night and they were more comfortable than I expected! I didn't feel wobbly or unstable, from stairs to cobblestones to sticky bar floors...I was good!
