Looks old school", but the all new Triton by Sherwood is a new fin with three vents between the foot pocket and blade that provide additional thrust on the down kick and decrease drag on the up kick or recovery. Foot pocket shape and size derived from years of research to satisfy the most exciting requirements for comfort and power. The Triton Fin is positively buoyant and floats if they come off. This open heel fin has adjustable straps with quick-release buckles and a large heel pull tab that combined for easy donning and doffing. The fin blades ribbed design focuses the water down the length of the blade for increased power and thrust. The Sherwood Triton Fins are made from a lightweight, durable Thermoplastic Polyurethane (TPU) material. Recent testing by Scuba Lab shows the Sherwood Triton as best for power & acceleration and Sport Diver Magazine gave then the Editor's choice award for 2015. Fins weigh only 3.9 lbs. (1.77 kg) per pair making them great for travel.
