Product Customer Reviews

this is what we are looking for to replace ours which was broken.
Nice one
Thumbs up
Nickel to replace defective fins
Handy replicas for old surfboards
Perfect fin quality for easy and beautiful surfing with Decathon softboards.
good for drift loss!
Identical to those that were supplied with a new board.
Super quick to change, thank you
I was looking for a fin for my mouse board, Decathlon has solved it for me. The keel fits perfectly.
Hello, I have a decathlon surfboard with these flexible removable fins (very good product, which secures surfing activity and avoids any worries), however I lost the tightening key which was supplied with the surfboard. Can you tell me how to get a new one? Thank you Julian
Too bad often out of stock, not a lot of stock in Quimper,
great
I recommend especially when we take our first steps on the board
Sufficient for starting the sport.
