Though Birkenstock’s history stretches back over 250 years, their ascent into the fashion sphere has been more recent. Their instantly recognisable sandals, which are made on a cork, jute and suede-soled footbed, have become a menswear staple in recent years, thanks in no small part to a string of high-profile collaborations. Among the designers and brands to have reimagined the footwear are Rick Owens, KITH, BEAMS and Valentino.
