THE NOVELTY Dopie Sandals

This summer’s hottest beach flats, Dopie sandals (the result of a two-year collaboration between the industrial engineer Matthew Harrison and Terra Plana) offer the feet almost invisible support: the sole folds up between the big and second toe. So there are no straps to mess up your foot tan, but if you need extra support there is an optional strap that goes over the top of the foot. In pink, yellow, turquoise, red, orange, green and white. £25, lovethoseshoes.com.
