There's no better time than spring to add some pretty florals to your outfits, but that doesn't mean you're limited to delicate tees and skirts. Nike and Liberty London's newest collaboration launches next week, and the latest designs are anything but prim and proper. Turn the ladylike vibe up several notches of edgy with kicks that come in Liberty's 19th- and early-20th-century printwork patterns. The vintage paisleys and soft blossoms are featured on some of Nike's most athletic shoes, including the Air Max and Dunk Sky Hi. The collection goes on sale in-store and online on April 7th.
