rift sounds like you're talking about regular hockney's. the folk line came out in 08SS. i'm a 10.5 in nike's and both my americana deck folks are 11.
actually ive had both hocks and decks.
both in a 12 and both were perfect, and im a nike 13 (for comparison)
and yes youre correct 2008 seems more like it. excuse my error above. it seems like so long ago now, being 2011..
but yes the 12 is perfect for me, full size down, no socks
i still suggest anyone buying any vis to try on prior. otherwise its just too risky.
