Crafted to be the perfect nautical footwear, these long-lasting sailor shoes are made from a single piece of polished leather conditioned with a rich blend of oils and waxes, then hand-sewn with the finest craftsmanship: enhanced by a natural polish quality, they come with a leather sock lining, 360° rawhide lacing system, and non-marking rubber outsoles 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.
