The Newport is the foundation of the Keen footwear line. Designed to perform in the adverse conditions of a marine environment, the razor siped outsole and 3mm lugs provides excellent traction both on land and on the slick surfaces of boat decks or river rocks. A true hybrid, the waterproof nubuck upper withstands the abuse of saltwater and dirt, while providing supple comfort and a stylish look. Upper is made of environmentally preferred premium leather from an LWG-certified tannery. Non marking outsole rubber compound provides superior coefficient of friction for all environments. Razor siped pods on outsole provide increased surface area for greater traction on smooth surfaces. Compression molded EVA midsole is contoured for superior comfort and support of the foot structure. Elastic Closure with Cord Lock creates a quick, snug fit, while allowing flexibility. Waterproof nubuck leather upper wraps around the foot for stability, allowing generous ventilation. 3M Reflective pull tabs provide added visibility during night time adventures. Toe guard so you can worry about the activity, not your toes. AntiMicrobial EVA footbed inhibits foot odor and controls moisture.
