The Cressi Light fins are specifically designed for use in the pool and for swimming training, but they are also suitable for recreational swimming and snorkeling. The short blade is made of a highly responsive and lightweight material that ensures agile and effective kicks without tiring the legs. The blade length has been designed to ensure perfect muscle training without causing cramps or discomfort. The foot pocket is made of soft rubber elastomers and accommodates the foot with great comfort, even during long swimming sessions.
