Ocean Tested. Ocean True. Mark Cunningham signature — built by time in the water. Natural Gum rubber, zero additives, pure feel. A lifetime in fins led here. Comfort dialed all the way up, performance locked in. Soft, responsive, next-level fit — DaFiN at its cleanest. Features: Perfect balance of comfort and power. Fun for all water activities, from swimming to bodyboarding. Approved by the Hawaii Lifesaving Association and the USA Lifesaving Association. Fins float in salt water. Lightweight and ideal for travel. Can be worn on either foot. Made with high-quality natural rubber. Side rails extend halfway along the fin’s length, curving toward the blade to create a precise flex point. Raised V-shaped foot pocket combined with a rigid blade maximises water acceleration and propulsion with each stroke. Size guide: DaFiN/Kicks sizes are based on US Men’s Shoe Sizes. The size chart below shows conversion to Women’s, EU and UK sizing. Length is the most important measurement: heel to longest toe. Got the fins? Now get the mat.
