Crafted to be the perfect nautical footwear, these durable sailor shoes are made from a single piece of polished leather with hot-stuffed material conditioned with a rich blend of oils and waxes, then hand-sewn with the finest craftsmanship: enhanced by a quality natural polish, they come with leather sock lining, 360° rawhide lacing system, and non-marking slip-resistant rubber soles to provide stable grip in all weather conditions. The Portland mocs carry in their DNA an innate affection and bond towards the city of Portland, one of New England's largest seaports, also home to a world-famous yacht club.
