Swimfin features
The DaFin Mark Cunningham Signature Swimfins in the Black Sand colorway.
DaFin is the most powerful and comfortable fin in the water today. DaFin was developed in Hawaii by Andy Cochran, an Aussie who was one of Oz's early surfing pioneers. Cochran worked closely with two of Hawaii's most famous watermen, Mark Cunningham and Brian Keaulana, on the design of DaFin.
DaFin delivers top performance for lifeguards and bodysurfers. It is the most popular fin with watermen around the world. DaFin was recently featured prominently in the critically acclaimed bodysurfing film 'Come Hell or High Water'. DaFin is the only swim fin endorsed by the United States Lifesaving Association, the premier professional association of beach lifeguards and open water rescuers in the United States.

If you have wide feet or are at the high end of the size chart, we recommend going up a size and adding either a heel pad cinch or flipper slippers for a better fit. Customers with extra wide feet (E and larger) benefit from sizing up. See the swimfin size chart for help choosing.
Best For
- Lifeguards and bodysurfers
- Watermen and waterwomen who want comfort and power
Features
- 100% Malaysian Rubber: All natural, high-quality rubber. The blade offers rigid resistance but remains flexible where necessary. With less drag on the up kick, leg strain and cramps are reduced.
- Comfortable Foot Pocket: The pocket is silky smooth and soft over the top of the toes and foot to prevent blisters and chafing. The bottom of the pocket is rigid to transmit power to the blade. Fin socks or booties are not required for comfort.
- Lightweight: For such a powerful fin, DaFin is one of the lightest surf fins on the market. Less weight equals less strain.
- Extremely Powerful: Revolutionary design creating maximum acceleration of the water flowing over the surface, resulting in more thrust per kick.
- Maximum Control: At speed, the "strakes" generate a vortex of water from the trailing edge. This forms a barrier, helping to prevent outflow of water from around the raised foot pocket. The result is an element of control and maneuverability across the face of a wave or in turbulent water.
- Can be worn on either foot
- Floats in salt water
- Used by the World's Best Watermen: DaFin Ambassadors include Mark Cunningham (World Champion Bodysurfer), Zak Noyle (Professional Surf Photographer), and Brian Keaulana (World Renowned Hawaiian Waterman)
- Official fin of the United States Lifesaving Association and Hawaiian Lifeguard Association

Good to Know
- DaFin come from the factory with a white powdery coating in addition to some silicone film. This is all part of the manufacturing process, has zero impact on the integrity of the fins, and will disappear with use.
