Cressi’s Reaction adjustable fin has a long and relatively flexible blade that’s made from a new-generation technical polypropylene. This lightweight composite makes for a responsive fin throughout each phase of the kicking cycle.

Constructed of a flexible polypropylene blade and a thermoplastic rubber foot pocket in an open-heel design, Tilos’s lightweight Torrent fins offer increased flexibility, which translates to a more comfortable kicking experience.

The Pro Light is an extremely light and well-balanced fin that’s surprisingly responsive and powerful. The compact blade features a soft rubber center panel that’s flanked by thermoplastic stiffeners and flexible yet supportive side rails. This combination provides nice blade flex when kicking, and allows you to maintain stability whether you prefer flutter, scissor or frog style kicking. The fin has two flaps along the end of the blade, a design that allows divers to change direction with only minimal kicking effort.
