Divers’ little “engine” under water
In most places, they are called swim fins, or even flippers, but usually just fins. Without fins, a diver cannot undertake an effective dive.
There are two main types available in the market:
– Open-heel fins to be used with boots
– Full-foot fins for direct use on your feet
We can also classify them by their hardness or rigidity in use. Open fins are more expensive, and one must add the cost of neoprene boots or the like.
Hard fins will give a diver more momentum than soft ones, but they may prove to be more tiring or uncomfortable. This is why we recommend finding a balance between hardness and comfort. Fins are also made of different materials, like plastic, resin or carbon, among others.
You must be able to tell if fins are for snorkeling, freediving or scuba diving. Snorkeling fins are too soft and are usually short and closed, although they are the most economical.
Freediving fins should be more flexible and longer, but they have a high price tag because of their resistance and the materials used to make them.
Fins for recreational diving should be medium-sized, with a price point starting at 25 euros. These will be the focus of our attention.
As noted, you can choose from either open-heel or full foot fins. Open-heel fins have a rear system for adjustment with rubber and metal clamps, and they can usually accommodate different-sized feet. Use of boots with open-heel fins is virtually mandatory if you want to protect your feet from scrapes or when walking on sandy terrain.
Plus, the full-foot fin system is very simple: just put them on and use them. However, some divers do prefer to use normal socks with these fins if the fins are hard, so as to protect themselves from annoying scrapes.
