Boston Leather Sandals

Birkenstock offers an earthy-tan iteration of its signature Boston sandals which were introduced in 1977. They're made from leather to a backless form that's accentuated with raw edges and a buckled strap, then finished with the signature cork insole and rubber sole.

• Calfskin leather

With its famously comfortable soft cork footbed, the 250-year old Birkenstock brand is enjoying a new wave of popularity, with its Boston suede clogs, Madrid and Arizona sandals stealing the spotlight thanks to cosy shearling and big buckle iterations.
