Mares X-Stream Scuba Diving Fins

The Mares X-Stream are the highest-rated open-heel scuba diving fins available, used by technical divers, rescue divers, and advanced recreational divers who need maximum propulsive efficiency for strong current diving. The channelled blade design uses four parallel channels to direct water flow precisely through the fin stroke for maximum thrust per unit of leg effort, and the polypropylene/thermoplastic rubber composite construction provides the ideal balance of stiffness and flex for sustained power in overhead environments and strong tidal conditions.
