I wear size 39.…

I wear a size 39. The size 38/39 was tight on my feet (yet I have long and thin feet). On the other hand, the size above 40/41 is a little large for me. Half size would have been perfect. I took size 40/41 anyway. I was able to swim without worry. Just stay attentive and put it back a little at times... Fins bought to work on the legs and cardio. I like them in terms of use. As for the colors, meh...

Very good for training

Great fins, you can feel the slight resistance when swimming and how your muscles are strengthened. The color could be more subtle but you can't see it in the water anymore.

Awesome

Work the legs really well, very different from normal fins but worth it

Additional Product Information

Composition

Blade (for diving): 100.0% Styrene Ethylene Butadiene Styrene ; Shoe: 100.0% Styrene Ethylene Butadiene Styrene

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.
