Reef started life back in 1984 when the Aguerre brothers took their love of surfing and beach life and turned it into something proper. They began making sandals in Brazil with one simple idea – create something you can live in, whether you’re heading to the beach, travelling, or just kicking about in the sun.


Fast forward and Reef has become one of the biggest names in the sandals game, known for that perfect mix of comfort, durability and easy-going style. These are the sandals you chuck on without thinking – and then realise you’ve basically lived in them all summer.


And then there’s the absolute icon… the Reef Fanning. Designed with surf legend Mick Fanning, this thing is next level. Super comfy, solid underfoot, built to last – and yes, it’s got a bottle opener built into the sole. Genuinely one of the best and most fun ideas ever put into a pair of flip flops.


Reef just gets it. Good times, travel, surf, sun, and not taking things too seriously. If you’re after sandals that feel great and bring a bit of personality with them, you really can’t go wrong.
