Technical information: WHAT ARE SWIM FINS FOR?: A fin is a piece of swimming training equipment to work the lower body. Swim fins are ideal for swimming faster, for longer. You can simultaneously work on your heart rate and muscle building on the lower body (thighs, glutes and calves as well as core stability) ; FIN LENGTH: LONG FINS - 37/39: 41 cm - 40/42: 42 cm - 43/45: 45 cm Long-blade fins maintain greater muscular exertion and ensure a more sweeping kick than short-blade fins. ; STIFFNESS: RIGID FIN The rigid fin design is guaranteed via orange plastic inserts. The more rigid the blade, the greater the muscle workout, the softer the blade, the fuller and more effective the stroke. It is the resistance of the blade that will generate the type of exercise desired (cardiovascular or muscle workout). ; FOOT POCKET: OPEN FOOT POCKET The foot pocket of a fin holds the foot in place when kicking (important for an efficient kick) so take the time to try on the fins before buying. It is important to check that the foot fits well in the foot pocket and the uncovered area (to prevent water from entering). It is important to choose the right size. There are two types of foot pockets: full foot and open heel.
