1. Looks good to me, but I can't say for sure what they'd actually send you. I'm inclined to say they're safe because they don't have new or popular styles on there; most of what they have is several seasons old and not really priced accordingly. You could find a lot of those shoes on eBay or in the outlets for $200-$300.
  2. If you have any questions about authenticity of those shoes, you should definitely post your questions at the "Authenticate Those Shoes" section.
