Sandals stopped being a fashion choice around the time German tourists adopted them as a uniform. Like the bulky cargo shorts guys from Düsseldorf often pair them with, sandals are a victim of their own design. Sturdy and breezy, they make perfect sense when you’re strolling over sun-scorched pavements. And because fashion hates function, that utility means they’re also adept at killing looks. Or, at least, they were.

In a piece of rebranding Justin Bieber would kill for, sandals have become an honest-to-goodness trend and infiltrated every major runway this season. At Bottega Veneta, that bastion of Italian swagger, dual-strap sandals were even paired with chunky socks. As Vogue put it, “[come 2016] German package tourists will be the very height of chic.”

As our Teutonic cousins know – and as the ancients learned long before them – sandals are the footwear grail when temperatures rise. “Beyond aesthetics, you need to consider comfort and convenience,” says David Morris, shoe buyer at Mr Porter. The sandal’s open design allows air to circulate around your feet, but pick a chunky enough sole and you’re sure-footed on-road or off.

Not that you should do your sandal-shopping in a mountaineering store. Where your dad favours sweat-inducing nylon and plastic, the front row’s version is all natural. “Soft leathers are good, because they’re breathable,” says Giles Farnham, head of River Island’s Style Studio. “They tend to give a lot, so choose a snug pair.” But nothing so cosy your toes hang over the end.

When it comes to styling, stick to cuffed trousers or chinos, which flash your footwear and stop any unsightly fabric puddling. A strict summer shoe like the sandal also works best with warm-weather fabrics; think a low-key cotton-linen suit, with a crisp tee and as much insouciance as you can muster.

But even without bum bags and football shirts, sandals veer irredeemably tourist if your feet look a mess. “Go for a pedicure,” says Farnham. It’s a moment of discomfort for feet that are actually worth seeing.

Birkenstock Mayari Cross Strap Sandal

The classic Birkenstock has endured since the 1960s. And for good reason; the cork sole is flexible and the straps minimalist, but effective. Unlike your yoga teacher’s favourite sandals, the Mayari’s straps wrap around your big toe. Which keeps your look from veering too classic.

Available at Birkenstock, priced £59.95.
