If cobbler extraordinaire Pierre Hardy’s new spring line is any indication, it’s hip to be square again. Inspired by the regularity of Moroccan tiling and the line drawings of Sol Le Witt, he raises the humble quadrilateral to the height of fashion with his new Cube Perspective collection of graphic footwear and accessories in coated canvas with leather accents. From bags and sneakers to laptop and iPhone cases, the line is a cross between Rudi Gernreich, M.C. Escher and a checkerboard. To celebrate the launch during the Paris collections, Hardy commissioned artist Tal Isaac Haddad to create an installation in homage to the square, drawing fashion’s finest to the Palais du Bourbon shop, including Rick Owens and L’Wren Scott. Our picks are the sneakers that re-envision the classic Hardy shape with a mod twist, a running start on fall’s romance with the sixties.
