Aqualung Dive Fins — Made in Italy, Engineered for Performance
Aqualung's fin range is manufactured in Italy — the same country that has produced some of the most respected dive fins in the world for decades. The lineup spans every diver type: lightweight open-heel fins for tropical travel, stiff-bladed power fins for current diving, full-foot fins for snorkeling and warm-water shore diving, and the Phazer — a high-performance blade-style fin with an armadillo-inspired segmented structure that represents a genuinely distinctive approach to propulsion design.
All Aqualung fins in this collection are open-heel (adjustable strap) unless noted as full-foot. Open-heel fins pair with dive boots for protection, warmth, and a secure fit across different footwear types. Full-foot fins are designed for barefoot or thin-sock use in warm water. At DiveCatalog.com, we carry the full current Aqualung fin range in multiple sizes and colorways as an authorized Aqualung dealer.
The Aqualung Fin Range
Aqualung Phazer — Premium Performance Blade Fin
The Phazer is the standout in the Aqualung lineup, and it looks unlike any other fin on the market. The blade uses a segmented "armadillo" structure — overlapping articulated sections that flex independently during the kick cycle. This design allows the blade to maintain efficient pitch throughout the entire stroke rather than flexing uniformly like a solid blade, which can waste energy at the beginning and end of each kick. The result is powerful, efficient thrust with less leg fatigue on longer dives.
The Phazer is made from Monprene, a thermoplastic material that provides the ideal balance of stiffness and flex for propulsive efficiency. Available in Black and Hot Lime/Dark Grey in Small through XL. Spring straps compatible; Aqualung's bungee strap upgrade is also available separately.
Aqualung Express SS — Travel Open Heel Fin
The Express SS is Aqualung's compact travel fin. It uses a spring strap as standard (unlike many fins at this price that use rubber straps) and features a blade design that balances propulsion with easy packing. Made in Italy, the Express SS is particularly popular with divers who split time between dive trips and want a reliable open-heel fin that doesn't take up half a suitcase. Available in Blue/White, Black/Black, and White/Dark Grey in Small and Medium.
Aqualung Storm — All-Around Open Heel Fin
The Storm is Aqualung's versatile mid-range open-heel fin, built from Monprene for durability and consistent flex performance. Available in a wide size range (XS/S through 2XL) and multiple colorways including Navy Blue and White/Yellow. The Storm's blade geometry suits recreational diving across conditions — suitable for tropical reef diving, moderate currents, and shore entries. An accessible, practical choice for divers who want solid Italian-made quality without the premium of the Phazer.
Aqualung Storm Max — Long Blade Power Fin
The Storm Max extends the Storm's proven Monprene construction into a longer blade format for divers who need more power — particularly useful in current, for underwater photography (where controlled hovering matters), or for photographers and videographers who spend time finning against flow. Available in Black and Orange/White colorways in Small through XL.
Aqualung Stratos ADJ — Adjustable Open Heel Fin
The Stratos ADJ features an adjustable foot pocket that can be sized to fit different boot thicknesses without swapping fins — useful for divers who alternate between thin wetsuit boots and thicker cold-water boots. Made in Italy. Available in Black/Dark Grey and Blue/Dark Grey.
Aqualung Stratos 3 — Full-Foot Fin
The Stratos 3 is Aqualung's full-foot fin for warm-water recreational diving, snorkeling, and shore use. Full-foot fins fit directly on the foot without boots, making them lighter and more compact for travel to tropical destinations. Available in an extensive size range and multiple colorways.
Open Heel vs. Full Foot — Which Should You Choose?
Open-heel fins use an adjustable strap and are worn with dive boots. They suit cold-water diving (boots for thermal protection), shore diving on rocky entries (boots for protection), and divers whose foot size may vary with different boot thicknesses. Full-foot fins fit directly over a bare foot or thin sock, making them lighter and more compact — ideal for tropical diving, boat diving where boots aren't needed, and snorkeling. If you dive in both conditions, open-heel with thin boots is the most versatile single solution.

Fin Sizing
Open-heel fin sizing depends on the boot you'll wear inside the fin — not just your shoe size. A size 10 foot in a thin 3mm wetsuit boot takes up less space than the same foot in a 7mm cold-water boot. Aqualung provides size guides for each fin model. When in doubt, try fins on with the boots you plan to dive in. Contact our team if you need sizing help.

Frequently Asked Questions — Aqualung Fins
What makes the Aqualung Phazer different from other fins?
The Phazer uses a segmented blade structure inspired by armadillo scales — overlapping articulated sections that flex independently throughout the kick cycle. This maintains efficient pitch across the entire stroke rather than the uniform bend of a solid blade, which translates to more thrust per kick and less leg fatigue over a long dive. It's a genuinely distinctive design with no direct equivalent in the Aqualung lineup or in most competing brands.
What is Monprene and what fins use it?
Monprene is a thermoplastic rubber compound that provides a good balance of stiffness, flexibility, and durability. Aqualung uses it in the Storm, Storm Max, and Phazer fins. It handles temperature extremes well, resists UV degradation, and maintains consistent flex characteristics over time.
Do Aqualung open-heel fins come with spring straps?
It depends on the model. The Express SS includes a spring strap as standard. The Phazer and Storm use rubber straps as standard; a Phazer Bungee Strap upgrade is available separately. The Stratos ADJ uses a proprietary adjustable buckle system. Check the individual product listing for strap details.
What fins are best for cold water diving?
For cold water diving with thick drysuit or wetsuit boots, you need an open-heel fin with an oversized foot pocket. The Storm and Storm Max both accommodate thick boots well. If you're diving with drysuit rock boots specifically, verify fit carefully — contact us and we can advise based on your boot type.
Are Aqualung fins suitable for cave diving?
The Storm and Storm Max are reasonable choices for overhead environments in their respective blade lengths. For cave diving specifically where the frog kick and modified flutter kick dominate, many technical divers prefer rubber paddle fins (like the Apeks RK3 in our Apeks collection). Contact us if you'd like a recommendation for your specific technical diving application.
From the Phazer's armadillo blade to the compact Express SS, the Aqualung fin range covers every style of recreational diving. Browse the full collection above and reach out if you'd like help choosing the right fin for your diving conditions and boot type.
