I've bought from both, IIRC when I bought from Amazon it was cheaper because Zappos was only selling the current year's model but someone on Amazon was selling the previous year's for less. I don't think I got counterfits, if I did I never noticed. I've also noticed Zappos is also frequently out of stock in a lot of sizes, it seems very plausible they could be out of stock on a color or size that's in stock on amazon.com.
