Swim fin for use by e.g. diver during sea-rescue activity, has tightening units supporting sides of support part, and exerting pressure on upper surface of foot-receiving part during tightening to retighten slit of foot-receiving part

摘要

The swim fin (1) has a connection unit connecting a flexible foot-receiving part (2) and a rigid support part (3). The foot-receiving part has a slit (7) on its upper surface (8), where the slit partially extends on the length of the foot-receiving part. Tightening units (9) are arranged between the foot-receiving part and the support part. The tightening units directly or indirectly support lateral sides (3a, 3b) of the support part, and exert pressure on the upper surface of the foot-receiving part during tightening to retighten the slit of the foot-receiving part.
