The Light was designed for swimmers to train. It can also be used for snorkeling when a larger fin blade is not practical. The short fin blade allows for a precise, quick kick that requires little effort while still being very effective. The length of the fin blade and the materials used are the result of specific studies aimed at enabling perfect muscle training without the occurrence of painful cramps. The front edge of the fin blade is protected by a profile made of soft elastomer, providing safety for other swimmers. The foot pocket was designed on a computer and is made entirely of soft elastomers. Thanks to these materials, high wearing comfort is guaranteed even during prolonged use. It is relatively wide in shape, making it easy and comfortable to put on.
