Too rigid

Too rigid. Needs a bit of flexibility. Mine are too hard to use in the water. I

Snorkelling fins are great

A light and easy to carry pair; used once in the surf and worked really well with speed and catching waves.

Snorkel fins for our Cairns trip

We realised our daughter had outgrown her fins just days before our holiday. After looking in many stores and finding nothing worthwhile or very expensive pairs $50 and upwards, we remembered to look up Decathlon. The late night trading also came in handy for us, so we went over one night and were pleasantly suprised. The range of fins available at Decathlon was fantastic and the prices very reasonable. The Subea fins looked great and are well made and were well under $20 which was perfect for a growing girl.

First Timer Snorkelling

Wore while snorkelling in the Maldives. Nice tight fit and although can be a little tricky to get on in the water they certainly won't come off while swimming or snorkelling! Be careful not to get sharp sand/stones in them while putting on the water as to me cost it is quite painful. Overall though very helpful while snorkelling in both calm and stronger currents and helped me swim much better than not using fins.

Convenient and Effective

Easy to get on and off. Fit well. Protected my feet (to some extent) and helped me swim whilst snorkelling.

Easy to use

Good value for money snorkelling fins.

Flipping good

Ordered fins online for my Wife. Click and collect was quick and easy. Fins fit her perfectly and look well made. Will be trying them out in the Florida Keys next week. Price was cheapest by far and are guaranteed.

Good Value

I bought these for my girlfriend who is not very experienced in snorkelling, for use in the Caribbean. The fins are short so they are easy to wear especially when entering the water, they seemed pretty durable although they didcontort and needed to be clipped back together into their transit mode to straighten out after use. They withstood coral contact well with a few scratches but not too much damage. For the price they are great for beginners and are fit easily in a suitcase.

Swim fins

Good price took them on holiday to Portugal. Have lasted well only thing that they do is bend and stay in that position. So both pairs have curved a lot. I'm guessing from using others this shouldn't happen. Other than that they were fine

Additional Product Information


Swimfin (blade)

  • 55% Styrene ethylene butadiene styrene

Foot pocket

The part of the fin where the foot is placed. It can be completely closed, like in full-foot fins, or open with an adjustable strap, like in adjustable fins.


The flat part of the fin that helps to generate the thrust. The longer and/or harder the blade, the more powerful the fin. The shorter and/or softer the blade, the less powerful the fin.

Storing your fins

A little tip: both fins can be clipped together (clips on the toe of each fin) to make carrying easier.

What is the difference between freediving and snorkeling?

At Subea, the Decathlon diving brand, we decided on a simple way to define the difference between our freediving and snorkeling products: From the moment you hold your breath and swim under the surface of the water even a few yards, it is freediving. Conversely, if one stays on the surface, this is snorkeling.

What is the subea brand?

Tribord Diving is now called SUBEA, the Decathlon brand dedicated to underwater sports (snorkeling, scuba diving, spearfishing and free-diving). The markings on all our diving products will gradually be replaced. Why SUBEA? Because: "SUBaquatic Experiences are Amazing"! For more information:
