OMS Slipstream Monoprene Fin

— Show original

So far, only experience with fitting the flipper to the foot. The upper edge of the back of the foot case pressed very unpleasantly on the junction of the metatarsal and the ankle, despite the excellent Ursuit neoprene shoe I was wearing. Fortunately, the flipper is thermoplastic plastic. So I modified it by making a wooden stretching jig for the mouth of the leg box and heating the problem area with a hot air fan to approx. 110 C (the power of the hair dryer was not enough). Editing was successful. Temperature monitoring during heating with an infrared thermometer and a thermal camera. I finished off the thick back edge of the leg box by sanding it thin with a rasp. Now the comfort of the case is decidedly better. The problem was the unnecessarily high tension of the rear spring. The length of the next accessory spring is probably too long (by eye, a couple of centimeters longer than the original), but maybe the longer spring can be shortened to the ideal length...

These jetfins from OMS Slipstream is very comfy. Works like the Apeks RK3 but it’s neutral buoyant instead of negative like the RK3. Weight is in between Scubapro’s and Apek’s so it’s great for travel

Very good product. I took XL with scuba rockboots 43, I had to change to XXL. Very responsive, large team, thank you again.

I love these fins ! Used to have them in XL . My shoe size is 40 . It worked but some Instructors told me they were to big . Now I have the L and they are a bit harder to put on as the shoe pockets just fit my booties but once on they are like feet - extensions. Incan kick very precisely, frogkick, backkick, helicopter turn and also the flutterkick is easy. With the xl that was much harder. There is a big difference in length between L and XL . Happy !

Probably the best find you can get. I probably should have gone 1 Suze bigger for my size 45 drysuit boots, but they fit with a push, and that means I can use them with a wetsuit too.

Great fins with neutral buyoncy when diving with a wetsuit.

Almost as good as the jetars

Nice solution to counter feet heaviness for Wetsuit Sidemount Diving. Is approx 1kg lighter than comparable JetFins. Stiffness and maneuverability is comparable.
