About Aqua Lung Express SS Fins

The heart of the Express ADJ is a highly elastic armadillo" hinge at the base of the blade. Like the Power Bands of the Slingshot, it absorbs energy during the power stroke and releases at the end of the kick cycle to maximize thrust. These open-heel fins are an excellent choice for cold and temperate water divers who need a powerful, compact blade. The Express ADJ now comes standard with the Aqua Lung Spring Straps for easy don and doffing.

Armadillo membrane at the base of the blade absorbs energy during the down stroke, and releases prior to the upstroke for a power boost on every kick. Rubber side ribs channel water down the length of the fin, minimizing wasted energy from the spill-over effect. A Mid-Foot Flex Joint is used to attach the blade to the side of the foot pocket. This maximizes energy transfer and reduces strain on the ankles and toes. ESBS (Ergonomic Strap and Buckle System) uses a press-to-release button that is easily operated, even while wearing thick gloves. Rubber heel straps are made with anti-aging compounds and have large finger loops at each end and in the middle for easy donning, even when wearing heavy gloves. Streamlined foot pocket provides an ergonomic fit for excellent energy transfer and accommodates a wide range of dive boots. Anti-slip rubber pads on the bottom of the foot pocket give traction for moving around on boat decks. Fins are available in multiple sizes and colors.

The Aqua Lung Express SS Fins is commonly used for SCUBA and more. The Aqua Lung Express SS Fins is most used by customers who consider themselves to be a Advanced, Beginner among others. The Aqua Lung Express SS Fins is popular because customers like the following qualities of the Aqua Lung Express SS Fins: Accommodates Boots, Comfortable, Efficient, Lightweight.

Good pair of fins - easy to put on

The large grab-handles make the fins extremely easy to put on or adjust; so much better than my previous pair from a different company. The fit (with booties) was as expected.


Most Liked Negative Review


Hard to Navigate

All over my experience with this company has been great. They ship fast. Hopefully the return exchange process will be smooth as well.

The ADJ fins are not really adjustable but adjustable springs are available.


from Port Byron, IL, US

The adjustable fins are not really adjustable. The pair I purchased had the spring straps which was not how they were advertised on Amazon. I went to the Aqualung web site, and it stated the ADJ would be with springs. I ordered a set of adjustable springs from Aqualung adding $69 to the final cost of the fins


Love Them!


from Madison, CT, US

Purchased theses fins after being disappointed with a different pair that were much stiffer. These are wonderful! Completed 7 dives with them including a deep dive and wreck dive. Sizes run big, I have a size 10 women's shoe and dive booty - ordered a regular and exchanged them for a small. Small fit perfectly. No complaints. Highly recommend.


Great service


from Pleasant VAlley, NY, US

The fins came fast and was exactly what I wanted. Fit perfect.


Great Fins


from The Woodlands, TX, US

I bought a set for my daughter as well as myself, both in Arctic White. I like having a color that stands out so on group dives we can easily identify each other under water. I had to work a little harder to ensure we got the spring straps, and not the rubber straps, because AquaLung switched to the spring straps this year yet continued selling the old style (understandably) until inventory was exhausted. I personally prefer the spring straps and they work very well for us.

Questions about this item:

Shopper  Why Did You Choose This?
PETER H  A good new type of power fin .
GUY K  My duaghter wanted these
Raphaella F  Do these accept the universal spring strap?
MARK Q  Sorry, I have not tried the universal spring strap. These are great fins, however.
Melissa S  I own these exact fins and love them. I have had no problems with the straps that come with the fins. I am not sure if the straps are interchangeable or accept a universal spring strap. Now that water temperatures have dropped my gear is packed away, but I recommend these fins regardless is they accepts a universal spring strap.
CHRISTIAN C  Yes they do
Dennis G  I'm experiencing foot cramps (along outer edge and top of foot) while reading these and a 5mm boot with medium sole. Based on shoe size and fit of fin, I purchased the correct size. Do I need a thinner boot...say 3mm or would a hard sole be better?
MARK Q  I use a 3 mm boot with a soft sole. My shoe size is 9. This seems to work well, and I have not had foot cramps with this fin. Try also different kicking techniques (more leg kick and less foot kick). These are great fins for me.
