I always keep a pair of these shoes in my closet. Theyre great flats. Ive probably purchased them 4 or 5 times in total. However, with this last purchase, one of the shoes had a very stiff, awkwardly bent in heel, making it too uncomfortable to wear. It was past the return window when I finally wore out my old pair and tried these on, so I couldn't return. Instead, I tried everything, from stretching the heel, using a hair dryer to loosen it, and buying those heel insert pads. Nothing has worked to reshape that heel, so these shoes are not wearable. Unfortunate, because they're usually really great shoes....
