- What actual physical stores carry them?
- Is there anywhere online that I could buy then return without problems if they didn't fit my foot? I have heard Zappos is good about it.
I'd recommend you go to a physical store to try them on before you buy. You'll end up trying on several sizes. I know for the Virbram's that you have to have an extremely precise fit or else it will rub against your foot when you where them. You want them to feel snug but not tight; if it is loose at all, try on a smaller pair.
Here in the southeast part of the US, Abbadabbas carries them. I got mine from there.
