Really had high hopes for this shoe, because I wanted one that I could walk in comfortably with a medium heel. They do fit very nicely, but sometimes I feel like my heel will slide off toward the instep-side of the shoe. I really thought this wouldn't be a problem due to the great coverage on the vamp, but it does feel like I'm going to twist my ankle if I'm not careful. I
guess I need a chunkier heel at my age. Oddly enough I feel completely stable in the Born Frederique which seems to have a higher heel and the
slingback on it isn't really super supportive -- it does the job.
