I love these, but I wore them once (and beside my feet killing me), the heel grip didn't stay in place. It kept turning when I walked. It was so annoying. Then I took it out and glued it and thought that was it. Well, as I walk in them around the house (trying to stretch them since they are a bit small...lol), I notice the dang heel thingy is turning again. Dude, these were $540 plus tax. So would you take them back to Saks? Is this a defect? Do I ask for another pair or for them to repair it? Do you think a cobbler can fix it or will it always turn if the metal inside is stripped, ya know? What do you think???
