Once upon a time, Birkenstocks were synonymous with hairy middle aged German tourists and butch lesbians. Then one day, some celeb or other started wearing them, they became a fashion statement, and before you knew it there were queues to get in to the Neal Street shop, and Heidi Klum was designing a line of Birkies. This season Birkenstock have launched some great new takes on their classic slide. The 'Fuji' ($85.95) is more of a flip-flop than a mule, and is made of 'Birko-Flor', the brand's trademarked synthetic upper. Resist the urge to buy cheap copies, there's nothing like the real thing when it comes to footbeds.
