Gives your glutes and hamstrings a really good workout in the pool. I definitely feel a leg burn when using these.

Naprosto doporučuji každému, kdo chce posílit nohy
Die Flossen sind mal was anderes und wirklich anstrengend
Són unes aletes molt pràctiques, el treball muscular es troba diferent del de les aletes rectes. Potser l'impuls és menor però m'agraden més
Me encantan pero debeis dar opción a talla 35-36...calzo 37 en zapato y la talla más pequeña que ofreceis queda litgeramente grande. Hay adultas, como es mi caso, que tienen pies más pequeños.....y les dejais sin opción porque este modelo no lo ofreceis tampoco en niño....
Trabajo más tronco inferior que con las antiguas
.
Me encanta como se ejercitan las piernas con ellas
Son cómodas,se adaptan bièn,y como llevo poco tiempo no se el resultado muscular .
No me sirven. Me desplaza las piernas hacia los laterales y me es muy difícil coordinar piernas y brazos. Voy mejor con las largas de Decathlon.
Son realmente muy cómodas y nadando notas como trabajan las piernas mucho mas que con las aletas normales
Estoy encantada con ellas desde que las compré, porque las utilizó desde entonces.
Perfectas y cómodas
Muy buenas
Una pasada !! Me han encantado !! Me las pongo para dar clases de natacion y se nota el doble trabajo que se realizar !! Las utilizo cada dia !!

What are swim fins for?
A fin is 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).
Innovation!
A lot of swimmers use fins to train their legs. This focuses the effort on the quadriceps and the hamstrings and seat are worked very little.To work these muscles, we have designed these fins with an angle of 38° on the blade, which increases resistance when the fin rises and reduces effort when it sinks. 150 tests carried out have allowed us to measure an increase inmuscle use of 19% on the hamstrings and 27% on theseat.
Fin length
LONG FINS- US W 5.5-6.5: 14.4”- US W 7.5-8: 15.4”- US W 9-9.5 / M 7.5-8: 16.3”SHORT 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)
Footwear
OPEN HEELFin 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 1st 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.
Storage instructions
Store fins in a dry place.
