Swim fins help to strengthen the large muscle groups in the legs that propel the body forward through the water and teach proper horizontal form.

Fins are typically made of flexible plastic, and mimic the shape of fish fins or duck feet.

They essentially function as extensions of the foot and ankle, giving every kick more power.

This is especially rewarding to younger children as they learn to control their muscles.

Fins are often used in children’s swim team practices as a way of preparing for meets and competitions, but any parent who wants their child to become a good swimmer should consider purchasing a pair.

Children must adjust to the unfamiliar sensation of swimming with fins, but once they do, they can be like little torpedos in the water. You can help them along by making an informed decision about which pair of fins will best suit your child’s needs.

There are a lot of choices out there, so below we have listed some of the best options for kids of different ages.

Accessories

- Fin Socks: Fin socks serve a purpose similar to normal socks; they cushion your feet and protect them from chafing. However, fin socks also tighten up fins that are a bit too big and help keep feet warm in cold water. While they are not always necessary, many young kids prefer wearing fin socks because they provide better comfort when wearing fins.

- Fin Savers/tethers: These lightweight, inexpensive pieces of equipment can end up saving you a fortune if you’ve got a kid who likes to swim in open water. Fin savers are small nylon or neoprene rings attach to your child’s angle and the heel strap of the fins, so that fins won’t be lost to the waves even in hard currents.




FAQ

- How should swim fins fit for my kid?

Swim fins should feel snug but not tight. Most fins are designed to be roomy, so what you’re really looking for is a good fit from the heel to the toe. Fins with an adjustable strap make it easy to ensure continued comfort for your ever-growing kid.


- Where are the best places to buy kids swim fins?

Scuba diving shops and swimming supply stores are excellent places to find swim fins, and have the added benefit of on-site professionals who can help you correctly size your child’s foot for fins. Another great source for the best retail options is to ask your child’s swim coach for a recommendation. Swim coaches are always ready to help parents find resources to make their child a better swimmer.


- What is the practical difference between short and long fin flippers?

Long fins take more effort to move but give each kick more propulsion power while short fins allow you to move faster and more closely resemble barefoot swimming.


- Should kids train with fins in a pool or the ocean?

It is recommended that kids first try out their fins in a controlled environment like a swimming pool before they attempt to use them in the unpredictable ocean currents. However, once your child has mastered the skill, they can take their fins into open water and show off for the fish! Parental supervision is advised at all times.




Conclusion - Which Fins Are Right For Your Kid?

The most important factor to consider when purchasing swim fins for your child is how they will be used. If your kid wants to improve their speed with fast strokes, then short blade fins such as Finis Kid Finz or Guppy Trainers will be most suitable. If your child wants to snorkel or improve their muscles for competitive swimming, then Finis Long Floating fins and Sea Lion Junior Floating Fins will be useful. If your child just wants to have fun and use their imagination while going a bit faster underwater, then the YiZYif Mermaid Monofin will be sure to inspire them.

No matter which fins you and your child choose, finding the correct size is key to getting the most use out of them. Once you’ve done that, your little one is ready to hit the water and swim faster than they ever have before, preparing them for a lifetime of fun and safety in water.
