🤔 Frequently Asked Questions

How do I choose the right size fin?

Select your EU shoe size for the best fit. These fins are adjustable, so if you're between sizes, we recommend sizing up for a more comfortable fit, especially if you plan to wear neoprene dive socks underneath. Refer to the size chart in the product images for additional guidance.

Are these fins suitable for beginners?

Yes! The long blade design provides excellent propulsion with minimal effort, making these fins great for beginners who are still developing their kick technique. The adjustable fit also makes them easy to put on and take off, which is ideal for new divers and snorkelers.

Can I use these fins with dive boots or neoprene socks?

Yes — the adjustable design accommodates light neoprene socks or thin dive boots. For thicker boots, we recommend sizing up one size to ensure a comfortable, secure fit without restricting circulation.

What is POM and why is it used in these fins?

POM (Polyoxymethylene) is a high-performance engineering plastic known for its exceptional stiffness, durability, and resistance to wear. In these fins, POM is used in the structural hardware components to provide long-lasting rigidity and reliability, while the silicone blade remains flexible for efficient propulsion.

Are these fins good for deep diving or just snorkeling?

These fins are designed for both! The long blade and silicone construction make them effective for surface snorkeling as well as deeper recreational dives. The extended blade length is particularly beneficial for deeper diving where powerful, efficient kicks are needed to conserve energy and air.
