OK, this season's must-have shoes just got a lot sexier, and we're looking to the Fall 2012 runways for a little further explanation. Two words: lace-ups. We're not referring to the more modest Victorian-inspired lace-up styles, but to all-out lattice detailing and open-front lacing iterations that beg for a double take. Tory Burch turned out a ladylike iteration by way of lace-up oxford heels, Rodarte showed off a rugged aviator-inspired rendition, and Balenciaga toyed with the idea of a spicier kind of athletic sensibility. It was when we laid eyes on Salvatore Ferragamo's sexy, velvet-infused flamenco pair, pictured here, that we knew. You don't need to bare it all to take on Fall's subtler brand of sex appeal — all you really need to do is subscribe to the laced-up look. Thus, we've scouted out the best 13 pairs to get the job done — just keep clicking.
