Smooth Leather Upper / Classic Footbed - Supergrip Sole Smooth Leather has a very fine grain so the surface feels smooth. The leather is durable and easy to clean. Supergrip shoes are the classic Birkenstock footbed with a professional grade durable non-slip sole. 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. We use and recommend Kelly's Cork Renew to protect and preserve the cork footbeds. Boston Supergrip now discontinued, to be replaced with the new Boston Pro.
