If I was going to not buy local where I can try them all on and pick the one that fits best, then I would be looking to buy from Dogfunk or Backcountry.com, not Zappos. To each their own, but seriously, purchasing snowboarding boots from a shoe specific sales website just doesn't seem like a good idea to me.
Yeah, i think dogfunk and backcountry would have a way bigger selection of snowboard boots but you have to pay for return shipping. Zappos has a pretty decent selection AND has the best return policy cause they are free shipping to your house AND its free shipping on returns too.
But yeah, if Dogfunk or Backcountry or Trusnow etc offered free return shipping, i would of probably order from them instead. Zappos selection aint bad though.
