The Boston clog has an adjustable strap ensuring an individual fit. The highest quality leather is used – between 2.8 and 3mm thick. Offered here in a luxurious suede leather and soft foot-bed. The Soft-Footbed provides superior luxury and is created by foam layers inserted between the cork and suede lining of the original Birkenstock Footbed. Microscopic air bubbles cushion your feet while providing arch support. These clogs are suitable for a range of occasions whether indoors or out.
