What are swim fins for?

A fin are a piece of swimming training equipment to work the lower body. You can simultaneously work on your heart rate and lower-body strength training (thighs, glutes, calves, core stability).

Fin length

LONG FINS- 30-31: 32 cm- 32-33: 36 cm- 34-35: 36 cm- 36-37: 40 cm- 38-39: 40 cm- 40-41: 44 cm- 42-43: 44 cm- 44-45: 48 cm- 46-47: 48 cmSHORT blade guarantees a good kick frequency and a good cardio workout. Movements are very close to “natural” swimming movements.The LONG blade guarantees a more sweeping kick and a stronger muscle workout.

Fin stiffness

SEMI-RIGID FINSThe STIFFER a blade is the more important muscular exertion will be.The more FLEXIBLE a blade is, the more efficient and sweeping the kick will be. Your muscular energy will generate the type of effort you’re looking for (cardiovascular or muscular effort)


FULL FOOTFin foot pockets hold the foot in place when kicking (important for an efficient kick).The OPEN foot pocket means the ankle can move more freelyThe CLOSED foot pocket supports the foot in its natural position

Your first time using a fin?

Be careful to not start too quickly! The use of the fins should progressively increase to let the legs and feet adjust and get stronger and to avoid hurting the Achilles tendon.
