What are Scuba Diving Fins

Diving fins are an essential piece of equipment for any scuba diver or free diver. Designed to help divers move through the water with ease and efficiency. But with so many options on the market, it can be overwhelming to choose the right pair.

On this page we’ll look at what diving fins are and what to look for when choosing the best pair for your needs.

What are diving fins?

Diving fins, also known as flippers, are elongated, fin-like structures that attach to a diver’s feet. They typically use rubber or plastic and come in a variety of shapes and sizes. The main purpose of diving fins is to increase the surface area of the foot. This allows for more powerful and efficient kicks while swimming.

Types of diving fins

There are three main types of diving fins: full-foot fins, open-heel fins, and split fins.

Full-foot fins

Divers wear full-foot fins barefoot and they cover the entire foot. They are typically for warm water diving and are more lightweight and compact than other types of fins.

Open-heel fins

Open-heel fins have an open back and allow for a diver to wear a dive boot. They provide more support and protection for the feet and are better suited for cold water diving.

Split fins

Split fins have a split down the middle, creating two separate blades. This design allows for a more natural and efficient kicking motion, making them a popular choice among free divers.

What to look for in diving fins

When choosing the best diving fins for your needs, there are a few key factors to consider.


The material of the fins will affect their durability, flexibility, and weight. Rubber fins are more durable but can be heavier, while plastic fins are lighter but may not last as long. Consider the type of diving you will be doing and choose a material that best suits your needs.

Size and fit

It’s important to choose fins that fit comfortably and securely on your feet. Fins that are too loose can cause blisters and discomfort, while fins that are too tight can restrict blood flow and cause cramping. Try on different sizes and styles to find the best fit for your feet.

Blade length and stiffness

The length and stiffness of the blade will affect the power and speed of your kicks. Longer and stiffer blades are better for strong, experienced divers. Shorter and more flexible blades are better for beginners or those with weaker leg muscles.
