I have a pair of the grey 2010 ones that are US 12 and they fit better than I expected because I usually wear 11, so I figured these run small. 11.5 would probably fit me really comfortably, but 11 would be snug. Probably still fit, but snug. So far the only ones I've seen online bigger than 11 have been the ones that BAIT just released online that ended up on ebay, and they all want over $1000 for them. I'd pay $500 for a pair, but none of the ones I've seen in my size have been anywhere near that low.
