Designers like Lanvin and Louboutin are taking fashion’s love affair with flats to new heights for their Spring/Summer 2015 shoe collections that focus on an enduring staple of summer style: the espadrille. Though the pieces in the new collections capture the espadrille’s easy, breezy spirit, designers have made more sophisticated versions, far cries from the simple rope-soled shoe that has been popular for many decades in Europe. The uppers of the shoes are revisited in an array of luxurious materials, from baby calf with a leopard print to delicate pastel shades on feminine sandals with slender ankle straps.

The same style catches the eye in the butter-soft leathers, and segues effortlessly from day to evening in silver or gold metallic lambskins. Alternatively, canvas versions printed with knotted rope motifs comes close to the classic espadrille style.

For cutting-edge style and comfort too, look no further than “flatform” espadrilles. These easy slip-ons on a chunky rope sole are interpreted in casual rope-print canvas’ for day and luxe iridescent calfskins for evening. It’s no wonder that fashion has stayed in love with this shoe – its versatility is endless.
