Tory Burch Ambrose Black Flats Size 12

Tory Burch Ambrose Flats - Black, Size 12. Purchased at Nordstrom and only worn once. These have very little sign of wear - the right shoe is in perfect condition and the left one has a little scuff on the back. These simply did not fit my feet well. I tried adding moleskin to the inside back but that still not help. There is a little residue from the moleskin (see pics). These shoes are in excellent condition overall.
