Great fins for this price

The drain hole opens toes from bottom, not ideal if have to stood of reef. Otherwise great for the price, compact, light. Also advantage they are inflatable.

Good light fins to have

Used these three times and pretty happy so far. Fins are pretty light, for well, don’t hurt, easy to put on/ take off yet are pretty snug and don’t walk off while swimming. I have used them for diving, relatively soft but good enough for my purposes. Great value for $

Good for beginners

Good to use as training fins only. Fins are bit hard but light weight

Good fins but slippery when walking in the water

Fins are wonderful but it is quite slippery and may drop off or quite loose so need to check size properly before you buy.

Hello Yeo,

Thank you very much for your review.

I am really happy to hear that you like the efficiency the SUBEA FRD 100 freediving fins. It's a multi purpose fin that can be use by intermediate snorkelers and beginner freedivers and scuba divers.

Yes indeed, the size has to be chosen properly. If the fins are slightly too large, we recommend to use it with a pair of neoprene socks:

This way the fins won't slip off and will be even more comfortable.

Hope to see you in one of our stores.

Have a nice day.

Great for snorkel and scuba

I've had these fins (older color variant) for over 2 year now, using them mainly for snorkeling/freediving and scuba. As long as there is a safe water access, you're good. Fins kept me moving around Taiwan and Indonesia and I appreciate the low weight when on the go. After two years (and 3+ months?) of abuse, the rubber boot part started developing minor cracks, but to be honest, I'd expect that much sooner given my daily use. Going for a new pair next time I'm in town. Will buy again.

Thank you!

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:

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 meters, it is freediving. Conversely, if one stays on the surface, this is snorkeling.



Storage instructions

We advise you to store the fins flat in a dry place away from direct light.
