The Marlin Cayman Full-foot Fins are comfortable, effective and versatile. They are perfect not only for diving and snorkeling, but also for spearfishing in the reeds. The use of the latest materials and the implantation of new technologies have made the blade more efficient. The two-component blade (polypropylene with rubber inserts) fins have holes-channels, which optimize the water flow during the stroke and give acceleration, thereby, reducing the charge on the leg muscles. The ergonomic rubber foot pocket fits well around the foot, providing maximum ease of donning and ultimate comfort for prolonged use.
