Imersion E: spearfishing fins

Q: Hello, I wear size 43-44. are the fins designed to be used with socks? will a size 42-44 fit me if i wear them with a 3mm sock?

It was nice fit and good products!foot size + sock thickness = appropriate fin size.In my case, my basical foot size was 42 + 3mm socks = fin size 44-46, which was a perfect fit.

IMERSION E:GREY Spearfishing Fins: Progressive Power for Every Diver

Dive into your next underwater adventure with the IMERSION E:GREY Spearfishing Fins, the ultimate choice for both aspiring and seasoned spearfishers and freedivers. Engineered for exceptional versatility and performance, these adult fins deliver a superior blend of power, efficiency, and comfort, allowing you to move through the water with confidence and grace. Whether you are stalking prey along the reef or exploring the silent depths, the E:GREY fins are your perfect underwater propulsion system.

At the heart of its design, the E:GREY fin uses the flexible progressive technology. This innovative system allows the blade to bend in a progressive arc, providing a soft, easy kick at the start and building to a powerful thrust as you apply more force. The result is an incredibly efficient kick cycle that maximizes propulsion while minimizing leg fatigue, enabling longer, more enjoyable dives. As a truly multi-purposed fin, it will satisfy all types of divers and free divers, adapting seamlessly to your specific needs and diving style.

Key Benefits:

* Unmatched Versatility: Perfectly suited for both Spear Fishing and Freediving, the IMERSION E:GREY is the one fin you need for all your aquatic pursuits. Its balanced performance excels in various conditions, from navigating shallow waters to making efficient ascents from depth.
* Superior Comfort for Extended Dives: The ergonomic, closed foot pocket is designed to cradle your foot securely and comfortably, eliminating pressure points and chafing. This snug fit ensures optimal power transfer from your leg directly to the blade, preventing energy loss and allowing you to dive for hours without discomfort.
* Durable and Reliable Performance: Built to withstand the rigors of the marine environment, the high-performance plastic blade offers the perfect combination of flexibility and resilience. It provides unwavering performance dive after dive, making it a reliable companion for all your underwater explorations.

Main Features:

* Flexible Progressive Technology: A sophisticated blade design that adapts its stiffness throughout the kick cycle for optimal efficiency and power.
* Ergonomic Closed Foot Pocket: A full-foot design that offers a secure, comfortable fit for bare feet or neoprene socks, ensuring maximum power transmission.
* High-Performance Plastic Blade: A durable and responsive blade engineered for an ideal balance of flexibility and thrust, suitable for a wide range of diver strengths and techniques.

FOURNIER OLIVIER

I already had the same fins for 5 years, I gave them to an Egyptian who had fallen in love with them in the Red Sea. I bought the same new pair. I do scuba diving and freediving, they are mixed. In addition, it fits in the suitcase to travel.

This is the second pair I buy, I had black ones for over 10 years called Escalapez, this time I opted for the green ones a little softer and I'm very satisfied. Excellent fins, comfort on the foot, lightness. Thanks

Very cool

I wear size 43 but the size 42-44. This this doesn't fit my feet properly. The main use in a pool. When I go straight it's ok. But when I do a turn my heel come out. Might buy a diving sock ??

Excellent ther

Berle

I really like these fine. The foot pocket is super comfortable and I think the Blade is a nice compromise between stiffness and flexibility. Currently I'm diving beyond 30 meters, and feel no need to upgrade yet. I wear a size 46 normally and the 44-46 fits me perfectly. Just wish there was a bigger size for 5mm socks. These fins are quite powerful, and does Require some ankle and leg strength. My girlfriend has the Challenger pros Which are softer but with the Sami excellent foot pocket.

Aljaz

This is a very comfortable shoe design and a comparable sizing to my shoes size. I wear size 41 and size 40-42 fits perfectly. Also, the blades are not too stiff which makes them easy to use for longer periods of time. Can not beat price/quality ratio on plastic fins!!

For an Air Force 27cm wearer, boots around 26.5cm fit perfectly in the 44-46 size range, but they are slightly heavy. I think I just have to get used to them

Beautiful fins

Dirk

Beautiful fins for a very affordable price. I normally wear shoe size 42.5 and bought these fins in size 42-44. Wearing neoprene socks is recommended because with bare feet the foot pocket is too spacious

Good fins

Iulian

Long (size 40-42 total length 90 cm), flexible fins. Wearing socks is necessary, as the foot pocket is large, bulky, and not very soft. Seems to be robust, good quality for the price

Everything ok !!

Bergvesting

Awesome product. Was my first fins years ago and will probably be my last. It is powerful enough for what I use it, and with 2.5 mm socks it is very comfortable.

Powerful. Size 44-46 for wide size 10 feet.

2020/08/19

Size 44-46 for wide size 10 feet they fit a little large. Width is great. 3.5mm to 5mm sock would snug it right up. They're powerful the propulsion is incredible compared to scuba style fins.

Excellent
