Adjustable swim fin in two parts - has separate shoe sliding in guide in fin and retained by rod fitting into holes in shoe

摘要

The swim fin is in two parts that can be separated, one forming the fin (1) and one forming the shoe (2). The fin has a guide channel (3) at the back with inclined lateral walls that form a dovetail. The bottom of the shoe (4) has a complementary shape and can slide in the guide. The shoe is held in place by a rod that passes through one lateral wall of the guide. A stud on its extremity fits into one of a series of blind holes in the lateral face of the shoe to adjust the length of the fin.
