Depends on what's wrong with your foot and your podiatrist is what I found. A friend of mine went to a sports medicine clinic in Boston and had his made for $100 a couple of years ago. They haven't gone up in price because a couple of years ago, another friend of mine had hers made and they were $300. Carbon ones are obviously going to be pricey, but from what I understand, certain foot conditions aren't happy about carbon ones or overly stiff ones as you can develop plantar fasciitis from them. I would say make sure you find a doc that understands cycling but it's so hard. There is a place in Peabody, MA called Fit Werx- not sure where you are but you might want to check them out, I think they have an online store and they sound like they know what they are talking about. I'll be making the trip once someone figures out what's wrong with mine.
