Buy monofins:
How to make the right decision

mermaid_fin_test

Monofins are based on the fastest marine animals and combine both feet into one fin. They allow you to glide elegantly and swiftly through the water while exercising your whole body.

Monofins have become increasingly popular in recent years, particularly due to so-called “mermaiding”, i.e. dressing up and swimming as a mermaid.

Not sure whether monofins are right for you?

The advantages and disadvantages of monofins at a glance

  • Ideal for freediving

  • Technology must be learned

The best is yet to come:

BeyondSurfing shows you which features are essential when buying monofins and how you can recognize real quality. A well thought-out purchase will pay off 10 times over in the end!

What you need to consider when buying monofins (incl. Checklist)

When looking for the right monofin for you, you should definitely pay attention to the following features and characteristics:

  • Material
  • Size
  • Model
  • Durability
  • Comfort

You will also receive valuable tips for use and an insight into the history of the monofin!

The best material for monofins?

The fin blade is made of plastic, glass fiber, carbon fiber or carbon and glass fiber composite. The material is thickest at the foot pocket and becomes thinner towards the edge of the fin blade.

The different layers of the fins are designed in such a way that the fin blade remains flexible but dimensionally stable.

Note: The thicker the fin blade, the more water is displaced. A higher speed can be achieved, but the strain on the muscles is correspondingly greater.

The right monofin size?


“Putting on the tight monofin is not that easy. It’s very important that you wet the fin and your feet first before you slip in. And you can’t do without the soap. Without it, we usually can’t get into the tight monofin at all.”

Wencke Orth ★★★★★
Orientation diver from Rostock


Which size is right for you depends on whether you want to use the monofin for leisure (e.g. in combination with a mermaid costume) or purely as a piece of sports equipment for water sports:

  • Recreational: Unlike “normal” fins, monofins for recreational use are often available in one size. Many manufacturers offer adjustable straps. There are also neoprene foot pockets that securely enclose several shoe sizes at once. This is particularly practical if you want to share the fin within the family.
  • Water sports: However, the sportier versions should be tailored to your foot. A well-fitting monofin tends to exert pressure on the foot. This is necessary to transfer the power ideally to the water.
Pro tip: neoprene socks increase comfort enormously and reduce pressure on the feet!

Which is the right model for me?

monofin_mermaid
Many factors determine the best, individual monofin. Everyone has different preferences in terms of swimming style. The fitness you bring with you also plays a role.

Important:

Never neglect the fit of a monofin – it must be snug to prevent loss of power transmission while paddling.

BeyondSurfing recommends:

It is best to test fins from other swimmers first! This allows you to determine which foot pocket comfort, hardness and angle of the fin blade you prefer.

If you can’t find a rental monofin, it makes sense to buy a cheap fin with soft material first. Less effort is required with flexible fins, making it easier to work on the correct swimming technique.

If you or your children just want to play a little mermaid, then you should choose a model that fits into a costume. Complete mermaid sets are often already available to buy.

How can I recognize comfort and durability?

A monofin is not a slipper. You will inevitably feel some pressure on your feet. This is the only way to paddle effectively. However, the fin should not leave any blisters or other injuries. Make sure the material of the foot pocket is soft and snug, so that it wraps around your foot like a second skin.

The durability is 50% influenced by your handling and care of the fin. Observe the following care instructions so that you can enjoy your monofin for a long time:

  • Chlorine and salt water must be rinsed off after each use!
  • Never store in direct sunlight.
  • Only use mild cleaning agents.
  • Do not scrub.
  • Use a protective bag during transportation.

The other 50% of the shelf life is due to the quality of the manufacturer. It is worth taking a look at our list of renowned brands and sellers.

A brief history of the monofin

The largest marine mammals, such as whales, move with natural monofins. Animals known for their strength and speed have flat, horizontal, semi-rigid fins. A Russian swimmer first took this as her model in 1971.

Svetlana Uspenikaia competed in the 1971 EU finswimming championships with the world’s first “artificial” monofin. It attracted a lot of attention but also skepticism with its design. In the end, she was far superior to all the others in the competition with the monofin and won by a large margin.

Nowadays, these fins are often used for a variety of competitions. Especially for the sport of apnea diving, which involves deep diving without oxygen equipment. Power, speed and control are important. Once mastered, the monofin is more efficient than two separate fins.

Monofin technique: How do I use monofins correctly?

You don’t learn the right technique overnight. You should first practise the movements on land before going into the water. In this video, orientation diver Wencke shows you what this movement sequence looks like:

It can be difficult to find the position where your whole body works together. Please note the following points when swimming with the monofin:

  • The correct posture is a straight line with your arms stretched out above your head.
  • One hand must be placed over the other and the arms held as close together as possible.
  • The aim is to minimize the surface area that the water encounters.
  • The more fluid and compact the movement, the less resistance!

You’ll soon be swimming like a dolphin with the monofin:

With monofins, the paddling movement is not just limited to the legs. It must extend from the center of your chest to your feet. Imagine a dolphin! Dolphins glide through the water in a streamlined fashion, using their entire bodies.

It is easier to paddle from the knee to generate power. However, this is nowhere near as effective as using the whole body. Almost every muscle from your shoulders down should work.

Tip: Only train for a short time at the beginning. Muscle cramps can quickly become a problem for the inexperienced. So proceed slowly and pay attention to your body signals. If your muscles feel tense, it’s time to rest.

FAQ: Frequently asked questions and answers about monofins

What is a monofin?

A monofin is a water sports device that makes swimming more efficient and faster. In appearance, it resembles the tail fin of a dolphin. Both feet are attached to a semi-flexible fin blade in a narrow foot pocket.

It helps professionals to perform better in freediving. It is also used by deep, distance and orientation divers and for butterfly and dolphin swimming.

In recent years, the monofin has become increasingly popular thanks to mermaiding. For this, she is incorporated into a mermaid costume.

How much does a monofin cost?

You can expect to pay between €20 and €60 for leisure activities. There are even some sets with mermaid costumes. Depending on what you are looking for. Professional fins for apnea sports(e.g. from Mares) cost a good €600.

How do you swim with a monofin?

A good role model is the dolphin. The entire body is used in a streamlined manner. Unlike other fins, you don’t just paddle from your legs and knees. All muscles must work together to perform a flowing, wave-like movement. The arms are usually stretched straight above the head, the hands crossed.

Would you like to learn the whole thing? In Bad Segeberg, for example, there are special courses to learn how to swim with monofins and a mermaid costume:

Where can you buy monofins?

You can find a wide range of products online at Amazon. If you prefer to get advice in a store, Empty is a good choice.

Which monofin is good?

There is no one-size-fits-all answer to this question. It always depends on what the fin is to be used for. In general, you should stick to renowned manufacturers and ensure a good fit. The aim of the fin should also match the model. Professional sport or hobby mermaid? You can find more details here in BeyondSurfing’s ” Buying guide.

What do you need to look out for in a monofin?

The fit, quality and degree of hardness are important factors and must be tailored to your training level:

  • The fin must not be too loose, but should not hurt the foot either.
  • The material must be of high quality and durable so that you can enjoy the fin for a long time.
  • A fin that is too hard is too strenuous for beginners and would lead to overstraining of the muscles.
  • However, it offers more drive for advanced users.

You can find more information on this in BeyondSurfing’s detailed ” buying guide.

Conclusion: The most popular monofins

Monofins are all the rage. The sequence of movements is much more elegant than with normal fins and trains the entire body. In addition, there are endless possibilities for use: apnea diving, butterfly swimming, snorkeling, playing mermaid …
