Chunky sandals take on a whole new form with these H&M Chunky Mules (£17, originally £25). With a cushioned slider shape over the front of the foot and a rounded footbed, they offer maximum comfort with minimum effort. The contrast of the neutral grey and black smooth sole would look great with cropped trousers and shirt in summer. They have a lift of 5cm, meaning you can add some extra height to your outfit without having to wear heels. And they come in cream and black, too.
