发明名称 Ergonomic swim fin apparatus
摘要 The ergonomic swim fin apparatus comprises a foot-pocket sized to fit about a user's foot, channeling scoops are positioned on opposite sides of the footpocket, and a flexible blade extends from the foot-pocket to a trailing edge. A "wing shaped" tail fin is secured to the trailing edge of the flexible blade. The channeling scoops are rounded to channel the water displaced by the user's foot over the flexible blade and tail fin. The flexible blade and wing like tail fin channel water while enhancing lift and thrust. At least one securing strap is used to secure the user's foot to the foot-pocket. The tail fin is preferably selectively attachable and removable from the distal end of the flexible blade. The flow of water across the foot is converted by the channeling scoops into a propulsion stroke in both the up and down strokes, while allowing the foot the freedom to flex naturally at the ankle and toe joints.
