Shoe designer Bettye Muller is a total tread-head. A former footwear model, she’s also an enthusiastic shoe collector who has, at times, owned 500 vintage pairs. Since the 1980s she’s worked as a shoe designer — crafting luxe boots, pumps, and other styles that reference the many world cultures she's experienced. In Muller’s hands, classic silhouettes get cheeky twists like candy-bright hues, vintage prints, and interiors lined with faux fur. Muller's sky-high cotton wedges, suede knee-high boots, super-chic stiletto sandals, frayed canvas espadrilles, and stacked-heel patent-leather Mary Janes are worth the extra storage space they'll require — even if your closet is as jam-packed as hers is.
