Soft and comfortable. Maybe better for people who has rounder feet. My boys’ feet is skinny so it keeps coming off...

Hi Christina,

Thank you for your feedback for our Swimming Training Fins. I am glad you enjoyed our product.

Our fins range from sizes between EU 30-31 to EU 44-45, and are made of soft material for more comfort. Usually, when swimmers wear fins for training, they would prefer to get a pair which does not come off easily.

One way which you can decide whether the fins are the right size for you is by wearing the fin and raising your heel. If your heel comes up easily, it means that the fin is too big for you. Hope that this information is useful for your next swimming fins purchase!

Thank you for your support, and see you soon at Decathlon!

You should provide free containers or bags for your costumer’s item/s. Its not appropriate to let your costumers carries those bought items barehand if ever he/she fails to bring bags/containers or dont have a choice but to buy those reusable bags of yours.

It helps me wade the water, i feel fast when using it. It can also be worn when freediving, snorkeling or scuba diving

The fins are very comfortable to wear. The rubber is soft and follow my feet, help a lot to build up thigh muscles.

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 muscle building on the thighs, glutes and calves as well as core stability.

Fin length

LONG BLADE: - 30/31: 12.6" - 32/33: 14.2" - 34/35: 14.2" - 36/37: 15.75" - 38/39: 15.75" - 40/41: 17.3" - 42/43: 17.3" - 44/45: 3.1" - 46/47: 18.9" "Long blade" fins will ensure more physical effort and a more sweeping kick and maintain greater muscular exertion.


SEMI RIGID FINS Stiffness is characterized by the density of matter, so the more rigid a blade is, the greater muscular exertion will be, the softer a blade is, the more efficient and sweeping the kick will be. It is the resistance of the blade that will generate the type of exercise desired (cardiovascular or muscle workout).

Foot pocket

FULL FOOT FINS 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. There are 2 types of foot pockets: Closed and open, the closed fin keeps the foot in its natural position.



Storage instructions

Store swim fins in a dry place.

Care instructions

Rinse swim fins in fresh water after each use.
