If you're a fan of 'dad' sneakers then you'll be thrilled about summer's counterpart: the 'grandad' sandal. Chloé's functional 'Sonnie' version is made from panels of mesh and snake-effect leather with a neoprene heel tab to prevent rubbing. They're grounded on chunky gripped soles and have adjustable crossover straps inspired by hiking boots. Check out PorterEdit for styling tips.
