Rocketfin

FINS FOR UNDERWATER SPORTS

For players of all levels seeking the best performance in a comfortable, high-quality fin.

Rocketfin is a Ukrainian brand that has been manufacturing the best monofins for world champions since 2005. Now, it has designed bifins for Underwater Games with the same quality and technology, aimed at players who want to achieve their highest performance.

Underwater Games are unique and innovative sports that stand out in the athletic world—and those who practice them know it and feel it.

Rocketfin has experimented with bold and vibrant colors so you can match them with the rest of your gear and stand out underwater.

Foot Pocket

Made from superior-quality rubber—comfortable, flexible, and highly durable.

Its snug fit, combined with the inner foam insert, ensures optimal grip and greater efficiency by improving the transfer of power from your kick to the fin. Excellent for enhanced agility during turns and direction changes.

Sizes:
S: 5–6 (shoe length 21 cm)
M: 7–8 (shoe length 23 cm)
L: 9–10 (shoe length 24.5 cm)
XL: 11–12 (shoe length 27 cm)

Blade

The fin blade offers better snap-back on each stroke than any other on the market, optimizing energy use while swimming. Its high flexibility coefficient reduces the likelihood of blade breakage.
Dimensions: Length 45 cm × Width 25 cm

Stiffness levels:
• Soft
• Medium
• Hard
• Extra Hard

The bumper and rails comply with CMAS international regulations and are officially approved by the Chief Referee.

Bumper

Made of high-quality rubber, bonded using specialized processes to ensure longer durability compared to other fins on the market.

Stabilizers (Rails)

The stabilizers help maintain fin stability while kicking, preventing side-to-side movement. They also enhance swimming efficiency by reducing water resistance and turbulence.

Care and Use

Here are some tips to help your fins last longer and perform their best:

Care

• Transport safely: Since they are made of fiberglass, handle them with care to avoid accidents or damage. Ensure your bag protects them properly during travel.
• After each session, rinse off pool chlorine with clean water.
• Avoid sun exposure to preserve the rubber materials.
• Check the stabilizers regularly: these pieces are glued on and may come loose over time. You can reattach them using instant adhesive.

Use

• Wet the fin’s foot pocket in the pool and apply a little soap around the edges and your feet for easier fitting. Some athletes use petroleum jelly for this purpose and to prevent chafing.
• If the fins feel too tight, use neoprene toe covers (only at the tip) to reduce pressure on the instep.
• Avoid letting anyone step or sit on your fins when out of the water.
• Do not press them forcefully against hard surfaces (e.g., floors, walls, pool edges). Fiberglass has a limited flexibility range, and exceeding it can cause breakage.

If you’re not used to fiberglass fins, we recommend ankle strengthening exercises to optimize your performance and prevent injuries.
