Birkenstock's Boston clog is a timeless, backless loafer. Part-slipper, part-slip-on, it reflects Birkenstock’s commitment to functional, quality footwear. Since 1976, the Boston Birkenstock has kept its iconic contoured footbed. Whether in orthopedics or fashion, the original cork-latex footbed has remained the foundation—moulding to the foot and helping to walk as nature int***ed. Today, Boston clogs continue to transc*** age, tr***s, and geography; the brutalist-inspired upper is the only element that changes. This Boston 'Birk' has leather on the single-buckle upper.
