I received my pair today, and was disappointed due to the slipping on my heels.  They slipped enough where it would be a tad annoying.  It slipped more on my left foot since that foot is a bit smaller than my right.  The shoes are very comfortable aside from the heel slipping, and will have to return both pairs that I ordered.  I purchased the Navy and Burgundy.  I'll receive the Burgundy pair tomorrow and will return both together.  I'm exchanging them for a half size smaller and hope that helps with the heel slipping issue.  The shoes are very well constructed, and the leather is soft.  It's a great shoe, and I'll be totally disappointed if the half size smaller doesn't work either.  Wish me luck!
