Klogs updates the classic Mary Jane with a sporty looking, full-grain leather upper. Adjust the fit with two hook-and-loop straps - one over the instep and one around the heel. Cushiony polyurethane underfoot and flexible slip-last construction combine to give you the "WOW" Komfort experience. The slip-resistant, non-marking polyurethane outsole absorbs shock, helping reduce impact on your feet all day. A microfiber upper lining absorbs odor and wicks away moisture for a dry, healthy foot environment.
