Alpha Fins

Formerly the Zura Alpha Swim Fin, the first injection molded EVA foam swim fin launched into the aquatic fitness market, the Aqua Sphere Alpha Fins are a lightweight, durable fin specially designed to give you an isolated leg workout regardless of the stroke you choose.

Contoured Blade Designed for All Strokes

The Aqua Sphere Alpha Fins feature a different style blade than the traditional swim training fin. Their contoured shape allows these fins to work well with the breaststroke, crawl and butterfly. Built-in water channels and technologically advanced blade design and construction provide stability and optimum power transfer from each kick.

With right and left foot offset profiles, the Aqua Sphere Alpha Fins encourage body rotation that adds power to your kicking motion. Alpha fins also feature full arch support for maximum comfort.

Buoyancy Promotes Proper Alignment

The Aqua Sphere Alpha Fins are very lightweight. They are 70% lighter than the traditional swim training fin, providing the added resistance for your leg workout without weighing you down.

EVA foam is a durable, non-waterlogging material that provides buoyancy, resulting in improved body positioning throughout your stroke. Because the fins have flotation properties to them, they create an optimum positioning for the Breaststroke kick.


Each pair of Alpha Fins are available in blue only.

SIZE US Size European Size
XXS 33-35
XS 4-6 35-38
SM 6-8 38-41
MD 8-10 41-44
LG 10-11.5 44-45.5
XL 11.5-13 45.5-47
XXL 13-14 47-48.5

If you are unsure of which size to choose or are between sizes the safe bet is to choose the larger size. The Alpha Fin is occasionally known to fit smaller than sized.

AquaGear recommends a Speedo Mesh Equipment Bag to protect your Aqua Sphere swim training fins. The mesh material allows airflow for natural drying of your aquatic equipment.

If you like the Aqua Sphere Alpha Fins, you should also check out the Finis Positive Drive Fins, which feature a unique asymmetrical design for use with all swim strokes and are designed to increase leg strength, foot speed and ankle flexibility.

The AquaGear Opinion

These odd shaped fins are unique feeling―and unique looking! The Alpha Fins EVA foam floats in the water, which promotes high kicking and proper alignment. The curved shape channels water around the Alpha Fins for an easy, and more powerful, breaststroke kick. They add great power to the breaststroke kick, and feel great with the butterfly as well.

The Bottom Line

The Aqua Sphere Alpha Fins are a different looking training fin that will add intensity to your lower body workout while also enhancing body positioning even during the breaststoke. Build a better stroke entirely with a pair of Alpha Fins from!

I've suffered with chronic back pain all my life. I took up swimming several years ago, and tried using Zoomers. They made the situation worse, and so I stopped swimming. I purchased Alpha Fins a few months ago, and am swimming better than I did thirty years ago. I have no back pain whatsoever because they help my feet stay up in the water. I swim everyday because of Alpha Fins.
