ECCO FLOWT WEDGE LX W sandals are made of genuine leather and nubuck from the ECCO brand's own production. ECCO FLUIDFORM™ technology forms an anatomically correct outsole and attaches it to the upper using a vulcanization method without glue or threads. The polyurethane outsole is lightweight, flexible and durable. A thin Velcro strap allows the sandals to fit comfortably on your feet. Genuine leather lining and insoles give a pleasant feeling of freshness and softness.
