What is the difference between Pro Force Fin and the Original Force Fin?
Pro Model Force Fin vs. Original Force Fin
Original and Pro Model Force Fins are made in the same mold. They are the same size and shape. The difference is in the chemistry of the material used for production. The Original is flexible, soft and easy kick. The Pro Model is stiffer, takes a little more kick strength.
A durometer is used to measure hardness of material. The Original Force Fin is specified as shore hardness 86-88; The Pro Force Fin is specified at 90-92.
As for application, the Original Force Fin is more versatile, kicking equally well for recreational SCUBA, on the surface snorkeling, and for deep kicking to increase kick strength swim training exercises. A more flexible blade surface swims better than a stiff blade. The Pro Force Fin outperforms the Original when at depth, under heavy load, such as technical or military diving profile.
Both are among the most efficient fins, and for SCUBA both are excellent fins. The difference in flexibility or stiffness of material, is really about matching the blade to the kick strength and preference of the diver.
The Pro Model Force Fin is preferred by strong kickers, instructors, technical, military divers, SCUBA divers who have used heavy, long, stiff, other fins, and want to use the feel of the fin as their frame of reference for forward momentum.
The Original Force Fin is preferred by soft, easy kickers, and superior swimmers. Why the two ends of the spectrum. Very good swimmers use different cues for forward momentum than the feel of the fin on their feet and legs. Those who are more relaxed in the water prefer a softer, easier kicking fin.

I am looking forward to my first
Open water dives with the Force fins
I have Force fins that I bought in about 1990. They worked very well with my drysuit and hard-sole boots but I would now like smaller ones because I now use a wetsuit with soft-sole boots. I have looked at the size chart on your website but cannot determine the size of my current fins from that because, based on the shoes I have bought over the years, my feet seem to be right on the edge between US 8.5 and US 9.
The distance across the outside of the very back of the foot pocket of my fins is 9.0 cm and the distance across the front tips of the fins is 29.7 cm. From those measurements, can you tell me what size my current Force fins are?
My guess is the size designation – located in the heel – has worn. If you hold your Force Fins and move them in the light, you should see the size in the heel. Generally dry suit boots require wearing an XL or XXL. There really is not much of a difference between 8.5 and 9, and size is most related to size and WIDTH, bootie sole style. I would recommend a size ML of your foot is narrow, and Large if wide.
is thier a way to tell if a force fin is pro or original without the box
The best way we tell is by feel. Hold the fin by its foot pocket and push back the blade as if you are kicking it. If it bends easily it is original, if it takes some push it is a Pro Model Force Fin.
Does the Slim Fin come in the soft or hard durometer? Is there a choice?
Slim Fin is made using the same material as the Original Force Fin We do not make it in any other durometer – more flexible or harder, such as the pro model force fin for diving – at this time.
