Will definitely let you know when I spot one, but they aren't really popular out here so they rarely pop up for sale.
A friend of mine is/was selling his Livestrongs in suze 9,5, but his price is a bit high ($350 for a used pair). You should also check ebay.co.uk, there was a Brown Hideout pair...
I'm from The Netherlands and we have Marktplaats, which is sort of comparable to eBay or Craigslist. Size 11 worn 2/3x for like $200 +-
Oh and d4mn you for those Mexico's, never see a pair pop up for sale, there's one on projectblitz.com but it's a 10.5 :(
Sorry for the late reply, but here are some pics: http://www.flickr.com/photos/62993811@N02/sets/72157640003216126/
IMO the sizing is pretty much TTS, some people even took a half size up.
^Just got my pair, they are very nice in person but not worth the retail price imo (especially not the European price tag), my guess is that these will end up in the outlets (European Nike website still has 95% of the sizes in stock)
