Product Information

Open Box Oceanic Viper 2 OH Fin delivers fast, responsive performance for scuba and diving. A precise blend of hydrodynamics and materials technology supports comfort, efficiency and power. Engineered channels and side rails direct water flow off the tips of the fin, preventing water from spilling along the blade and delivering uncompromising thrust.

With an oversized blade and a flexible Power Thrust Channel, this fin increases thrust and efficiency. Power Vents reduce stress while accelerating water over the blade. The generous yet streamlined foot pocket fits a wide range of boot styles and minimizes drag. The Open Heel with quick-release buckles provides easy adjustment and compatibility with common diving gear. Available in five colors and designed for travel, it pairs well with scuba and snorkeling gear.

Size range includes 2XS through XL with USA and EU equivalents: 2XS 3-4 / 34-35, XS 4.5-5.5 / 35-36, SM 6-7 / 40-41, M 7.5-8.5 / 41-42, ML 9-10 / 43-44, L 10.5-11.5 / 44-45, XL 12-13 / 46-47.

Frequently Asked Questions

What is the difference between open-heel and full-foot fins?

Open-heel fins have an adjustable heel strap and are worn with dive boots, which protect your feet on shore entries and add warmth. Full-foot fins slip on like a shoe against bare skin or a thin sock, and are typically lighter and easier to pack. Most scuba divers choose open-heel fins with boots, while full-foot fins suit warm water, snorkeling, and pool use.

How should scuba fins fit?

Open-heel fins should be sized around the boots you will actually wear, snug with the strap set so your heel stays seated and your foot does not slide forward in the pocket. Full-foot fins should fit like a firm shoe, with no heel lift, no pinched toes, and no gap that lets water pump in and out. Too loose causes heel blisters and lost fins in current, and too tight causes foot cramps.

Should I buy dive boots before fins?

Choose your boots first and size open-heel fins around them, because sole thickness changes the foot-pocket size you need. A thin warm-water boot and a thick cold-water boot with a rugged sole can easily be a fin size apart. If you already own fins, bring them along when you buy boots so you can check the combination.

Are spring straps worth it?

Spring straps replace the adjustable rubber strap with a stainless spring that stretches on and off, so there is nothing to buckle with cold or gloved hands and no rubber strap to perish and snap mid-dive. They hold constant tension, which many divers find more comfortable and consistent. They are sized rather than adjustable, so match the length to your foot pocket and the boots you dive.

What are the best fins for travel?

For travel, length and weight matter most, so shorter blades and travel-specific open-heel or full-foot models pack more easily and save baggage allowance. Some fins have removable blades or compact foot pockets designed for luggage. Pack fins along the outside walls of your bag, where they also act as protection for softer gear.

What is the difference between paddle and split fins?

Paddle fins use a solid blade that transfers power directly, which many divers prefer for precision, control in current, and non-flutter kicks such as the frog kick. Split fins have a slit down the blade that lets water pass through, which generally makes flutter kicking easier on the legs but gives up some control and works less well with other kick styles. Neither is inherently better, so let your kick style, leg strength, and conditions decide, and try both if you get the chance.

How do I care for dive fins?

Rinse them in fresh water after each dive day, paying attention to buckles, springs, and strap channels where salt collects, and dry them out of direct sunlight. Store them flat or hanging from the foot pocket rather than standing on the blade tips, which can take a permanent bend. Check straps, buckles, and any screws before every trip, since a failed buckle is the most common fin problem.
