It's not Birkenstock's Boston clog as you know it. The Boston 'Birk' is a single-strap suede slip-on shoe, now with a single piece of EVA (ethylene vinyl acetate). The part-slipper, part-slip-on is lighter and more flexible, waterproof and shock-absorbent, too. As always, the Boston style reflects Birkenstock’s commitment to functional, traditional, quality footwear. EVA Uppers EVA Insole EVA Footbed EVA Sole Unit Made in Germany Style Code: 127133
