The BIRKENSTOCK Boston is a practical classic that can easily be worn all year round. The Boston has a legendary status thanks to its sophisticated, individual design. Slip them on and you're off! The Boston clog is equipped with a strap and buckle that can be adjusted across your instep– and thus provide a perfect fit. The anatomically shaped footbed and roomy toe box makes them comfortable to wear creating a pleasant environment for the entire foot. These features make the clog a comfortable companion, whether indoors or out. The Birkenstock Soft Footbed features an extra layer of cushioning foam built into our legendary footbed. A unique foam layer built from millions of microscopic air bubbles is inserted between the top layer suede footbed liner and the layers of cork and jute that make up the rest of the footbed. This ensures a cushioned yet firm foundation for immediate comfort and full arch support, built on the most solid foundation in footwear.
