The company's experienced shoe team has incorporated advancements in materials technology into the new design to offer a supportive, comfortable shoe that's easier to get on and off. The outsole is nonmarking, provides excellent traction and sheds mud. The upper is made from a durable polyurethane-coated, polyester-based synthetic leather. The boot's light color reflects the sun to keep your feet cool, and it won't fade. Lightweight, high-filtration polyester mesh keeps sand and debris out and drains water quickly; channels at the heels provide additional drainage. The Marlwalker II's insole is made of removable EVA foam and has a gel pad insert for comfort and arch support. The ankle-bolstered support and foam padding reduce impact when wading on hard bottom.
