Buyer’s Guide
Without the proper free diving fins, you’ll be exerting far too much energy when you submerge, not to mention you won’t be able to maneuver your body with ease. There are multiple features that the perfect fins should have, including:
1. Blade Material
There are a few different materials your fins might be made out of, each of which has its advantages and disadvantages. The most popular include a polymer (plastic), fiberglass, and carbon fiber.
- Polymer: This is a fantastic material for beginners who need durability and affordability. It’s likely you’ll be dragging your fins against rocks and other hard surfaces when you start, you’ll need a more rugged material. For experienced divers, polymer typically has less power transfer and over time, they may lose their shape.
- Fiberglass: If you’re interested in going deeper with your dives, you’ll want to consider transitioning to fiberglass as it gives you better snap and better power transfer. Over time, they won’t lose their shape or stiffness. With that said, fiberglass is also far more expensive than polymer and they’re also more fragile.
- Carbon fiber: Many free divers prefer carbon fiber over all else as they offer the best performance and are lightest blades to wear on your feet. They’re highly reactive and give you the ability to easily navigate through all types of weather conditions. However, they are the most fragile material and require a lot of attention and care if you’re packing the fins or wearing them in shallow water.
2. Foot Pockets
The foot pockets are where your feet will slide into the fins so that they become an extension of your body. Not only should they be comfortable, but there are also two different types to choose from: separated and integrated (full).
- Separated: These foot pockets will usually be fastened using two clips on the side rails, which is ideal for people who are constantly taking their fins on and off. They’re also recommended for people who frequently switch their blades due to wear and tear.
- Integrated: Integrated foot pockets can be more comfortable, especially if you want your fins to feel like they are a part of your body. This design is far more streamlined and reduces a lot of drag once you’re in the water.
3. Tendon Thickness
Commonly referred to as the rails, the tendons on your fins give them the support they need. If you opt for fins that have thick rails, they’ll make the fins stiffer, whereas thin rails will make the blade less supported. The thicker the rails, the less likely the fins will be overstressed to where they break.
4. Comfort
The majority of your comfort will come directly from the foot pockets and as you will be under the water without any excess equipment, you need to make sure you don’t have anything impeding your diving.
All foot pockets are created differently, though it’s advised you consider fins that are designed with orthopedic support in mind. They should be fully cushioned and should also be sized properly to your feet.
5. Stiffness
The stiffness of the blades on your free diving fins will depend mainly on your experience level and preference. Some divers prefer stiff fins, whereas others find they impede their efficiency. It’s all about finding the perfect medium for how you prefer to move in the water.
Fins that are too soft typically require extra movement, which means you’re likely to become more fatigued and use up more oxygen. Another downside to soft fins is the likelihood of lactic acid build-up. Stiffer fins, on the other hand, help you to go deeper with less effort.
Best Free Diving Fins FAQs
1. How Do I Size Free Diving Fins?
When you’re sizing free diving fins, you’ll want to pay attention to the foot pocket. Depending on the manufacturer, it’s likely the foot pockets are sized similarly to regular shoes. For example, if you wear size 10 shoes, you’ll need a size 10 pair of fins.
It’s also important for you to think about available space in the fin. If you’re ordering your fins online and find they are slightly too large but not too big to wear, you need a new size.
You may need to consider wearing neoprene socks to make them fit perfectly. If you want to wear socks with your fins, it’s recommended you size up from your regular shoe size.
2. What Is the Best Stiffness for Free Diving?
Professional free divers suggest that very stiff fins are the best option for people who want to dive deeper with less effort. The blades of your fin will easily cut through the water so that you have the most fluid movements possible. For beginners, though, choosing a softer fin is more beneficial.
With soft fins, you won’t have to worry about breaking them in the water if you accidentally kick past a coral reef or a rock. Also, they allow you to get the true feeling of free diving fins.
3. How Do I Free Dive with Fins?
There are multiple finning techniques you can use once you’ve received your fins in the mail. It’s highly recommended you consider testing them out in a pool before heading out into a lake or an ocean, as it will help you to learn which technique is best for you.
Beginners should use the following tips when figuring out the correct positioning:
- Keep your head in-line with your body
- When kicking, use even strokes with straight legs and move the fins equally as far backward and forward
- Keep your upper body parallel with the bottom of the pool
4. What Are the Best Fins for Spearfishing?
There are three main features that best spearfishing fins should have, and they are reactivity, comfort, and durability. Your ideal pair of fins should limit the amount of energy you expel as you move throughout the water, allowing you to reserve more energy.
If you’re serious about spearfishing, it’s highly recommended you invest in carbon fiber fins with a comfortable foot pocket that you can wear for hours on end.
5. How Do I Wear Free Diving Fins?
If it’s your first time wearing free diving fins, knowing how to put them on quickly can be a process until you get a little more experience. With these easy-to-follow steps, you’ll be able to get under the water quickly:
- Step #1: While standing, cross one leg over the other and lean against a friend or a wall.
- Step #2: Using the opposite hand, take your fin and slide it onto your foot, repeating this step with the other leg as well.
