Just bought the perfect fitting painr of Louboutons at Bergdorf's. As my job requires me to run from one floor to the ER to the next (in flats mind you) I have begun to develop a small bunion on left foot. It makes wearing my left Louboutons painful after a few hours, whereas before they were perfect. A slight stretch on the left foot would solve my problem. Can I use my wooden stretch kit with the attachable bunnion (lol)? Or will the patent leather crack. It only requires a tiny stretch and I figured all you knowledgable leg ladies would be in the know. Help!
