Folding Fins®

The world's first Folding Fins, a true game-changer - developed and patented by Exotech. These specialized, lightweight fins can be folded in half lengthwise to create a travel-ready package. They can be redeployed for diving within seconds. The blade's flexible, durable membrane was inspired...

Interesting, weird but interesting.

Yes, very interesting design. No angle between blade and foot, which means they are mostly designed for frog kicking or the like.
It would be interesting to read their evaluation by technical divers used to the Scubapro Jetfin.

Interesting, weird but interesting.

I tried this concept years ago. The idea came from a Chinese hand fan. I did not like the buckling of the blade for tight turns. Hopefully, they can do well in this market.

Found Force Fin folding fin. 1998 Picture open blade. Very lightweight. Did several other designs for a Military folding fin. I will find more pictures.

From the link:

"When folded, they take up to 3 times less space"

I hate the "x times less" usage. Especially "up to x times less". What does that even mean and what's wrong with using fractions or percentages?

Is 3X less the same as 1/3 as much? Math always did confound me.

Math is easy compared to decent use of English, at which they fail.
