Similar to scuba diving fins, these fins are designed to help you move through the water with much ease and efficiency and without wasting a lot of physical energy or oxygen.

With these fins, you can dive at length, helping you get to the bottom faster and giving you the ability to cover more distance. They are stiffer and durable than any other type of fins such as those used for scuba diving or bodyboarding.

Thrust is imperative when moving through the water, but the human feet is inappropriately shaped and too small. With the help of these long flexible fins, freedivers and spearfishing experts have the freedom to move underwater stress-free.

Due to the length and design of these fins, you don’t require a high-frequency leg movement, which helps minimize oxygen consumption. These are long enough and designed to work with slow-stiff legged movements to conserve more energy and oxygen.

Swim fins used in spearfishing come in full-foot design and sturdy foot pockets. These features help reduce your weight and maximize power transfer from your feet to the fins. Generally, a good pair of swim fins used by spearfishers should be comfortable to use, long enough, and rigid in design.
