"It took me a really long time to break these flats in. Friends of mine had them and loved them, but they ripped up my heels so badly. I used Band Aid blister blocker directly on the shoe at one point. I'm not sure what happened, but all of a sudden they became the perfect, comfy go-to flat I had wanted. I like them now, but I wouldn't have gotten them had I known it would take this long. Maybe I have weird heels. I'm usually a 6.5-7 and the 7 was very loose. The patent is nice and cleans easily."
