Artful knots and a flash of cobalt give sophisticated pumps a playful edge. Proenza Schouler’s Jack McCollough and Lazaro Hernandez chose charcoal grey felt for this almond-toed style, which is topped by off-center bows that hint at the bright blue insole and lining. The play of textures is accented by a glossy, beveled heel made from high-density plastic coated in black lacquer.
