Fins are the single most important piece of kit in bodyboarding, ahead of the board itself. Without them you cannot catch waves properly, get through the impact zone or pull yourself out of a rip. They drive your propulsion, your safety and your progression.
In bodyboarding you paddle with your legs, not your arms. Your fins are your only engine in the water.



“I prefer to use more supple or less rigid fins for when the waves are pumping andI know that it may become one of those marathon sessions. More specifically for competition and bigger surf I prefer to use more rigid fins for their added performance of speed and acceleration when I need it.”
Jeremy Arnoux, Bodyboard Center team rider
“I also use softer fins but only when it’s small (Vulcan V2). When it gets big I need more stiffness, this is why I developed the Vulcan V3 with Pride Boyboards. It gives me more propulsion and holds better on my feet.”

Start from your normal shoe size. The fin should hold firmly without squeezing: heel seated, toes free of pressure. A bodyboard fin that is too large will come off in the impact zone and rub your toes and ankle bone raw, while one that is too tight will cramp your foot within twenty minutes.
Caught between two sizes, go down rather than up, unless you wear fin socks, in which case go up. Sizing differs noticeably between brands, so check the chart for the brand you are buying.

The most common mistake is buying a size up so the child can grow into them. It does not work.
These habits explain most of the wrecked pairs we see over the counter.
Always wet the foot pocket before pulling a fin on, water works as a natural lubricant. Slide your toes in first, then roll the heel over using the back tab. Pulling on the sides of the foot pocket is the main cause of a torn bodyboard fin, well ahead of normal wear. Reverse the same motion to take them off, releasing the heel first and never dragging on the blade.
Looked after properly, a pair of bodyboard fins lasts three to four seasons of regular riding. Left salty in the sun, it will not see out the summer.
What is the difference between symmetrical and asymmetrical fins?
Symmetrical fins share the same shape on both feet, so they are interchangeable, versatile and ideal to start with. Asymmetrical fins have a dedicated left and right foot and deliver more propulsion and more grip on the wave face, which is why intermediate and expert prone riders favour them.
Stiff or soft fins for a beginner?
Soft. They demand less leg strength, reduce cramping and let you build the kicking motion progressively. Stiff blades are for regular riders chasing acceleration.
How do I find my bodyboard fin size?
Start from your usual shoe size. The fin must hold firmly without compressing the foot, heel seated and toes free. Between two sizes go down, unless you wear fin socks, then go up. Sizing varies by brand, always check the official chart.
How long do bodyboard fins last?
Three to seven years depending on how often you ride and how you store them. Rinse in fresh water after each session and keep them out of the sun and heat.
Can I use swimming fins for bodyboarding?
Not really. Pool fins are too long and too stiff for the specific movement of bodyboarding. They restrict your kick, tire your legs quickly and do not deliver efficient propulsion in the surf.
Fins are not really chosen from a product page. Two brands labelled the same size can fit a full size apart, and that gap is exactly where the comfort of a two-hour session is decided.
Our two shops, in Hossegor and Carcavelos, exist partly for that. You can try models on with your own fin socks, walk a few steps in them and compare two brands side by side. The team rides the Landes beach breaks year round, including in winter, when the fin sock question stops being theoretical.
