Waterproof duck boot from Sperry. Heavy duty full-grain leather upper is stain + water resistant, constructed with sealed seams and a gusseted tongue to keep feet dry in wet weather. Lightweight injected EVA foam shell increases thermal insulation; complete with a non-marking lugged rubber outsole for maximum traction. Known for their boat shoes that have logged more miles of open ocean than any other, the Sperry brand has out-raced, out-cruised and out-sailed any and all competitors, again and again, from 1935 to this very moment.
