Aqualung Storm Open-Heel Scuba Diving Fins

Aqualung Storm Fins: Open-Heel Travel Fins Built for Simplicity and Versatility

The Aqualung Storm is an open-heel fin designed for recreational divers who want a reliable, lightweight option that travels well and works across a range of conditions.

If you dive regularly, move between destinations, and want a fin that fits over booties without fuss, this one is worth a serious look.

What Makes These Fins Different

The Storm is built from Monprene, a single TPV (thermoplastic vulcanizate) compound. TPV sits between rubber and hard plastic in feel: more flexible than rigid nylon fins, more durable than soft rubber, and noticeably light for its size.

That single-material construction keeps the fin compact and consistent. There are no separate inserts or multi-compound sections to delaminate or wear unevenly over time.

The X-Large weighs just 3 lbs (1.36 kg). For a full-size open-heel fin, that is genuinely light, and it matters when you are packing a bag or carrying gear from a boat to a beach entry.

The Foot Pocket: A Thoughtful Design Choice

Most open-heel fins require a bootie to fit properly. The Storm takes a different approach.

Its foot pocket is shaped to be comfortable with bare feet or with a thin bootie, giving you more flexibility depending on where you are diving. Warm-water trips where you skip the neoprene, cold-water dives where you wear a 5mm bootie, the Storm adapts without feeling sloppy in either situation.

A silicone bungee strap with a heel pad replaces the traditional buckle-and-strap system. Silicone bungee straps are faster to pull on and off than conventional straps, they do not corrode, and they hold their tension reliably over time. The heel pad adds a small but meaningful layer of comfort when you are standing on a rocking boat deck.

The underside of the fin also has a grip texture to reduce slipping on wet surfaces. A small detail, but a useful one when you are walking across a dive platform.

The Blade

The blade is non-vented and compact. Non-vented means the blade is solid with no cutouts or channels, so every kick pushes water directly behind you with minimal wasted effort. A shorter, stiffer blade like this rewards a steady, controlled kick rather than a long sweeping stroke.

For recreational diving at moderate depths and currents, that is exactly what you want. You generate consistent propulsion without burning through your air supply fighting a blade that is too stiff or too long.

There is also a transport hole in the blade, a small opening that lets you clip or hang the fins easily, useful for drying, storage, or hooking onto the outside of a bag.

Sizing and Identification

The Storm covers a wide size range, from junior sizes through adult. Aqualung uses color-coded bungee protectors and blade inserts to make size identification instant, which is practical when you are sorting through a pile of rental or club gear.

Because sizing varies by foot shape and bootie thickness, check the manufacturer's size chart before ordering rather than assuming your usual shoe size maps directly.

Who These Fins Suit Best

The Storm is a strong match if you:

• Travel frequently and want a fin that is light enough to pack without penalty
• Dive in varying conditions and want a single fin that works with or without a bootie
• Prefer a straightforward, low-maintenance strap system over traditional buckle straps
• Do most of your diving in recreational conditions rather than strong currents or technical profiles

Who Might Want Something Different

If you dive in consistently strong currents or do a lot of drift diving, you may want a longer, stiffer blade that generates more raw thrust per kick.

If you already own a full wetsuit with attached boots, a full-foot fin might be a lighter and more streamlined option for warm-water travel.

And if you are a technical diver using a drysuit with heavy boots, you will likely want a fin with a more robust strap system and a blade designed for the added resistance of thick suit layers.

For the recreational diver who moves between trips, dives comfortably in a range of water temperatures, and wants gear that is easy to manage before and after the dive, the Aqualung Storm is a practical, well-thought-out choice.
