Divers propel themselves by moving their legs (and the increased surface area of their fins) back and forth against the water with a flutter kick motion. We naturally have more strength when kicking down. The power or downward phase of the kick emphasizes the powerful quadriceps muscle group at the front and side of the upper leg. The kick's upward phase uses the weaker hamstrings at the back of the thigh and is mainly a recovery movement setting up the leg for the next power phase. The result is a natural two-stroke kicking cycle of power and recovery for each leg. While most flat fins make you work just as hard on the recovery as on the power phase, Force Fins take advantage of this two-stroke cycle and work in harmony with the body's natural strength. The flexible blade of our Force Fin opens out to its maximum surface area to move a high volume of water during the powerful downward portion of the kick. At the end of the downstroke, the blade snaps back to its original position, driving water behind at a high velocity and catapulting you forward while at the same time resetting and helping to recover your leg upward for the next downbeat. During the recovery, the blade folds down, channeling water behind while limiting resistance to conserve your energy. (If you have to put the same amount of energy into both parts of the kick, you fatigue much sooner.) Force Fins are the only fins that provide propulsion consistent with your natural two-stroke kick cycle to this degree. By providing for more of a separate power and recovery phase, oxygen depletion is reduced, and the onset of fatigue is delayed. The result is that divers can kick continuously for longer periods of time. Force Fins are made of an exclusive version of polyurethane that is heat-treated for 16 hours at temperatures that would melt other fins. Force Fins won't wilt when exposed to tropical heat, nor will they harden when ice diving.

For the price I’d have expected better quality less bubbles in the finished product
I have used force fins for years. In fact worked for the company that manufactured them. I have used seconds, these fins wouldn’t even have qualified as seconds I used 30 years ago as far as mold quality. For the price I’d have expected better quality less bubbles in the finished product. Would I recommend them, yes, they’re the best working fin on the market. Will these work? Yes. I just expected better quality control for the price.

Great fins; recommended!
Adv OW diver here, and I generally prefer easy shallow dives with no current. That said, I’m very happy with my Force Fins.I went through a long comparison process before deciding. After all, they seemed a little expensive. One thing that I noticed that set them apart from other fins; was that there were tons of used Force Fins on the market (some of which were very old) yet most were in great or excellent condition. This indicates to me a quality of construction; and that no matter what, this could be a Buy-It-for-Life purchase.There’s plenty of pros and cons for each person to weigh before making their decision. But I love mine! They’re strong, powerful, compact, and I’m not worried about them warping when crammed into my carry-on bag (yes, they fit). Also, I love how easy it is to walk while wearing them.

GREAT fins!
Been using these fins for decades. They're easy to walk in on beach or boat dives, because the tips turn up. My dive buddies, who are younger, stronger, and in better shape than me, have a hard time keeping up. I used to get cramps in my feet and calves before I started using these fins. I've not had them since I started using them. I usually wear them with the neoprene boots that are part of my dry suit, but on a vacation trip to warm water, I wore the "comfort insteps" and they kept the fit consistent and comfortable. Since the strap is nylon, it does not wear out. If you're not getting the same amount of power out of them that you got with other fins, you're not using the proper kick for them, kick from the knee, not the hip. They're great for traveling because they're shorter than conventional fins, so they don't take up much room in your luggage, if you're flying. I gave away all my other fins when I got these.They're not perfect though. They're expensive, but they're not going to wear out. You'll be giving them to your kids when you age out. Other divers will make fun of you, because they don't "fit the mold," so if you're more interested in form over function, stay away.

On two different dive trips fellow divers in remote areas tried my fins and after my final dive of the trip bought my used ones Yes they look funny, but just try a pair
I’am on my third pair of these fins, no I didn’t wear them out or lose them. On two different dive trips fellow divers in remote areas tried my fins and after my final dive of the trip bought my used onesYes they look funny, but just try a pair, you will not be disappointed

Save your $'s. The fins failed twice during normal use.
I lap swim about 30 to 40 mins. most days. The Force Fins failed after less than one year of use. Force Fin sent me a replacement and they also failed after less than a year. I never walked on them. I am not overweight or anything. This is an overpriced product that will not stand up to normal use.
