Technical Information

At OLAIAN we design bodyboarding products according to your level: Beginner, Intermediate or Advanced.

We use the following definitions:
- Beginner: Rides broken waves and waves <80cm; is learning to steer in the waves; does not duck dive (diving under the wave).
- Intermediate: Rides waves up to 1.5m; is in control of their line and can do a few tricks (360°, El Rollo, etc.).
- Advanced: Rides all types of waves and successfully lands all kinds of tricks, even aerials: ARS, 360°, inverts, barrels, etc.
NB: We recommend the use of fins for all levels.

These fins are designed for intermediate bodyboarders and provide the ideal comfort-to-propulsion ratio.

Comfort is provided by the softer material used in the foot pocket, as well as the leash's neoprene cushion at the heel.
Propulsion is provided by the stiffness and the surface of the blade: stiffer material and side ribs.
The symmetrical shape allows a good balance between kicking power and fin size.
For extra comfort, add neoprene socks.

Choose the right size of fins.

Always try on the fins before buying them. Your foot should be supported without being compressed. The back strap should be in contact with your heel and your toes should not be bent.
If you add neoprene socks for comfort and/or warmth, you will need to go up half a size. Consider trying the fins on with and without socks at the time of purchase.
Using or not using a fin leash will also require you to go up or down half a size.

Fin leash.

The leashes supplied with the fins help prevent you from losing them during the session. To put them on, first put your foot in the leash and then in the fin, before tightening the fastener.
The fin may come off during the session, but it will remain attached to your foot by the leash. You will then be able to put it back on.


A fin should be heavy enough to prevent it from touching the surface when you are kicking. As such, we designed a fin with slightly positive buoyancy so that it rises to the surface if you lose it, whilst still being able to keep it underwater without much effort when kicking.

Hold in the wave.

To ride down the line of the wave on a bodyboard and not swerve off to the side, you can use fins to help you. The side ribs will help you to stick to the face of the wave better and hold your line.
Asymmetric fins (e.g. RIP fins) can accentuate this phenomenon and require good bodyboarding skills since, with the thrust of the fin not being symmetrical, it results in additional twisting forces in the knees. It is therefore reserved for advanced riders.

Safety rules and behaviour in the water - Part 1.

Bodyboarding is a fantastic sport that requires certain fundamental rules to be followed for the enjoyment and safety of all.
1- Ask about and observe the characteristics of the spot: current, rocks, influence of the tide, wave size, number of people in the water, etc.
2- Do not overestimate your skills and choose an easier spot if the conditions exceed your abilities.
3- Use suitable equipment: Leash, fins and board in good condition, suitable wetsuit.

Safety rules and behaviour in the water - Part 2.

4- Follow the wave priority rules: Priority is given to whoever is closest to where the wave is breaking.
5- Go around the surfing area as you paddle out to the break to avoid getting in another rider's way.
6- Use fins if the water level is higher than your hips.
7- If you are not using fins, it is recommended to stay in the safe swimming area, ask the lifeguards present at the spot.
8- Ride with friends.

Also suitable for bodysurfing.

Although these fins are primarily designed for bodyboarding, they are also recommended for bodysurfing (with our Hand plane 100 for example). Its symmetrical blade and its comfort-to-propulsion ratio explain why it is popular with many bodysurfers, who surf waves with their bodies with the help of fins and boards (also known as hand planes).


OLAIAN is the new Decathlon brand devoted to surfing, bodyboarding & skimboarding. This Basque-sounding name is inspired by the universe of our development centre in Hendaye, in the Basque Country. It is the contraction of OLA, as OLATU means wave and IAN, a Basque suffix meaning “inside”. At OLAIAN, we see a potential playground in every wave and we want each person to be able to improve whilst enjoying themselves, regardless of their surroundings and their environment.
