At the suggestion of my podiatrist, I picked these up for my dress shoes. I have very flat feet and one of them decided it was going to cause me great pain every single morning and evening. Podiatrist told me that I could either try some insoles or get custom orthotics to fix the issue. I've tried Dr. Scholls and other brands to no avail but these things have an arch that is perfectly suited to my flat feet.<br /><br />Seriously, no more pain. I love them. They make my work shoes feel like sneakers. I also have a pair for my boots in the extra-wide configuration that are just great too.
