Luxuriously comfortable and resolutely practical, our unique all-leather Ultima boots give you amazing grip on slippery boats and complete freedom of movement. Why leather? Not only is it waterproof and fully breathable, but as the builders of Ireland's traditional curraghs have known for centuries, it becomes incredibly strong and supple when soaked in salt water. Made from the highest quality leather with Dubarry's award-winning NonSlip-NonMarking™ outsole, expandable Lycra® for a snug fit and GORE-TEX Product Technology, they'll keep your feet dry and agile in any weather.
