The Boston was introduced in 1976 with a strikingly brutalist silhouette and proved revolutionary for one specific reason: it offered a soft-soled clog as an alternative to the hard wood that dominated the category. It was designed by Karl Birkenstock and was the brand’s first closed shoe, allowing it to be worn at any time of year. It went by several names —“the soft clog,” “Formal Birkenstock Quiet Clog”— before becoming established as the Boston in the 1980s. The Essentials EVA version reinterprets that silhouette as a single piece of synthetic material.
The construction completely eliminates suede and cork: the entire clog is molded from EVA, a lightweight, flexible, waterproof material, including the footbed, which reproduces Birkenstock’s characteristic anatomical shape. Black covers the entire piece, including the buckle and sole, for a monolithic finish.
