CRESSIFin Keepers - Gives Full Fin Power, No More Lost of Thrust - for Freediving, Snorkeling, Scuba Diving Fins

Good fit and really help with security and lot losing fins not bad.

Wish I knew about these while I was bodyboarding, these are really great and work well, stretchy but strong

For about $11 you have an emergency back up for when a strap breaks on your very expensive fins in the Caribbean and cannot find replacement straps. I love my fins, but was unable to find replacement straps on the second day of my month-long vacation in the Caribbean. (I’m currently upset at the company that makes my fins as the strap is low quality and not considered part of the fin so they are not covered under the warranty). Thankfully, I had brought the fin keepers. I usually put them on when I’m diving or swimming deeper than I can go down to collect a fin in the event that one comes off or if I’m in an area where the water is turbulent at all as they keep the fins on your feet just as they claim. They do a great job and I will never travel without them if I’m using fins. Despite the fact that I was unable to find replacement straps, I used zip ties on the broken straps and used the fin keepers. By doing this, I was able to use my fins the entire month! I had at first purchased a pair locally when the strap broke, but they left my feet with blisters… for a small investment and very little space in your luggage, these are a must have!

Work great. There was no size chart when I ordered so here's a picture of the packaging with the sizes.

They work well.

They do the job just fine. The water was ruff but they worked.

These work great to secure swim fins from coming off. Especially useful in open water swimming.

Does what it says just very minimal. However if you swim for as long as me (about 1 hr - 1.5 hr). Definitely worth it.
