I love them but as an owner of that pair (in a different color) I have to warn you-they hurt. Theres' a tab of leather on the back that I can't figure out why it's there but it rubs againt my achilles tendon and hurts. It's not as bad with the flats as the heels. I own those too and they are the most painful pair of shoes I think I have ever owned in my life.
i know exactly what you're talking about. put these on and no more pain!
