I believe this is a new design, that adapts to a Wading Boot: http://www.cabelas.com:80/cabelas/en/templates/product/standard-item.jsp?id=0011322312111a&navCount=3&podId=0011322&parentId=cat20449&masterpathid=&navAction=jump&cmCat=MainCatcat20431-cat20449_TGP&catalogCode=IK&rid=&parentType=index&indexId=cat20449&hasJS=true
This is a good price compared to other retailers. The Reviews are interesting!

i believe they have been out for quite a few years. maybe cabelas are just now carrying them
Doug,
They have been around for several years. I picked up a pair at Sportsman’s Warehouse right after they opened at a very good price. I haven’t seen them in there lately. I’m not sure what the going price is now. And yes they will fit over wading boots.
Some of the reviews had me scratching my head. “can’t turn”??? I have no trouble at all turning with mine.
I guess that I never checked the Force Fin site, for these fins, because it never occurred to me they could update the regular model. I wonder if this is a case of “If it aint’ broke don’t fix it”?

I’ve had the adjustable FF for about 5 years or more and they are great.
I hope some day I have to race or out manoeuvre some of the reviewers because if they can’t figure out how to turn in a float tube…
Bamboozle,
If synchronized float tubes ever becomes an Olympic sport, we’ll have to team up and show 'em how it’s done. I was practicing my pirouettes yesterday.
Over five years here on the FF. I too bought mine at Sportsmen’s and they were barely over $100. Still in excellent condition…no wear on the neoprene at all and I can honestly say, these are THE ONLY flippers I have used that are NOT hard on the boot/shoes. Other fins I had literally cut my boot/shoes.
The only other flipper I have considered are these:
You have chosen wisely grasshopper. We have a review of those ( http://colo2.flyanglersonline.com/prorevw/flipfin.php ) and guess what. They are a new sponsor too. They seem to be pretty good. 
I can see they are good looking fins, but what make Force Fins worth $150? I do pretty good with a pair I paid $3 at a garage sale. Hey, I’m cheap, born poor and never fully recovered.
Force Fins are SPOON shaped. They curl up on the end so you can walk forward in them. The “V” shape makes them cut through the water better, then on the forward they SCOOP the water.
When bad weather hits you and you are in the middle of the lake, then you will appreciate this.
…and people think that fly fishermen dress funny…:rolleyes:
REE…will they fit over extra large wading boots?
I’m intrigued, but a little confused as to how they work. 
It seems that on the “up stroke” they would propel you forward, but on the “down stroke” the would propel you backward. It seems that you wouldn’t end of getting anywhere. Of course, I still haven’t gotten the hang of regular fins for float tube use either. :roll:
They ‘snap’ in place; stick out like regular ones then.
With Force Fins it is the same motion as bouncing a child on your foot while seated.
With the longer scuba fins, you can put your legs more straight out in front and move your feet the same as swimming so you would actually be propelling yourself on the up and down stroke.
It took me a long time to figure this out.
I have always been the type, the scoops the water up, then pull my heel back through the water and repeat on the other side.
But came across a group the uses these scuba fins. Of course, it still seems to me you would have to somewhat lean back and some boats don’t make this comfortable, so it is still up to the individual.
I appreciate the remark about the bad weather coming up when in the middle of the lake. That’s when I do aerobic float tubing, it is also the reason I carry a couple of hand paddles, cut from the side of a 5 gallon bucket with a flip flop sole handle. You can greatly increase your speed when Mother Nature calls you to leave the lake.
Very clever UJ…I used to use ping pong paddles…
Right on Uj…great idea, allot of people don’t think about adding arm power.
When you are on the far side of the lake and a thunderstorm slips up on you, realizing you are the high point of the lake and real slow is top speed, arm power helps. Lightning overhead is a great motivator. I happen to know I’m allergic to lightning.
One friend uses plastic dustpans and another frisbees.
I bought a PONTUBE that has oars…in fact I can add a motor, right Duckster!
