I couldn't find those straps on their web site...maybe they are used to hold the two fins together for transport?

Do let us know how they work out as I'm interested in a pair for myself for surface swimming, but hate to drop that many clams on pair that may or may not be all they're cracked up to be.

Ankle straps so they don't go to the botto of the ocean/lake when taking them when getting into the boat..

I have never liked the force fins - they're not very good in heavy current. They perform a lot like split fins (although slightly better, i think) but not as well as other fins. That being said, they are one of the fins used by the US Navy SEAL program (alongside Jetfins) - I was told this is because of their compact size, but based on my personal expirience with them, i'm guessing some admiral has a brother who owns the Force Fin company.

I know this is an old post:
Another reply regarding Force Fins from someone who has no experience using them. Force Fins work very well in heavy current when used correctly. In fact I personaly feel they perform better than any fin at this. You are not cramping up
while trying to move against a fast moving current. As for the NAVY Seals. They use Force Fins due to a test conducted
by the NAVY in regards to performance. If anyone is in the Detroit Michigan area and wants to test them let me know. You
won't be disappointed.

Also, they work great for photographers.(Professional Photographer)
