I'm pretty much an expert in walking around in platforms and heels, something I do five days a week for 10 hours a day (I own a clothing boutique), and these things were killing me. Even after sufficiently breaking them in. But they're so dang cute, I couldn't possibly return them. I already have custom inserts but I'm going to have to find a way to make them work. I'm ordering the zebra print ones, too!
