How to Choose Between Molchanovs Freediving Bifins: Training Fins for Beginners

How to Choose Between Molchanovs Freediving Bifins: Training Fins for Beginners
By Kristina Zvaritch and Asya Kleshchevnikova

So many Molchanovs bifins - how do you choose which is right for your training sessions as a beginner freediver?

Molchanovs has an impressive lineup of fins, but it can be confusing to understand which bifins are best suited for your needs as a beginner! This is exactly why we created a complete guide to Molchanovs freediving bifins. In this post, we’ll focus on bifins for beginner freediving training. Whether you’re training in the pool or open water, you need to know what features to look for in training fins, which pair is recommended for beginners, and potential upgrades down the line.

Let’s get started!

Features to Look For in Beginner Training Bifins

When shopping for bifins to kickstart your freediving journey, keep an eye out for three specific features.


Training sessions, whether in pool or open water, can take anywhere from 1 - 2+ hours, meaning the bifins you wear better be comfortable! Plus, if you’re still new to freediving, there’s a lot of things going on at the same time – a new environment, breath-holding, learning a new finning style, etc. If your fins aren’t comfortable or your mask is foggy or leaking constantly, it won’t be a pleasant experience. This is why your first pair of fins should be soft and ergonomic.

In bifins, comfort is all about the foot pocket. If your foot pocket is too stiff or rubs against your toes/heels and rips your skin open, it will affect how you dive. Thankfully, Molchanovs foot pockets are famous for their comfort!

While it’s best to try before you buy, that’s not always possible. So if you cannot try your bifin’s foot pocket before purchasing, measure your foot and check each bifin’s sizing guide closely.

When in doubt, email any questions or details at and get expert recommendation!


Building foundational bifin technique requires soft fins! And very soft fins, especially shorter silicone fins, will give you effortless kicks, allowing you to train your muscle memory to perform the correct movement. Then later, when you put on soft fiberglass or carbon fiber fins, you’ll still be performing the same bifin technique, just with the added resistance of longer fins.


If you are just trying out freediving for the first time, or still unsure of how much time and commitment you can give to it, you’re probably looking for affordable bifins for your first pair! Luckily, Molchanovs has a wide range of high-quality bifins at different price points, which brings us to our next point…

Do you know which Molchanovs training bifins are the go-to pair for beginners?

Molchanovs Training Bifins for Beginners (CORE Silicone Bifins)

The CORE Silicone Bifins are the ideal bifins for freedivers just starting out on their freediving journey! With a foot pocket designed for a comfortable and ergonomic fit (for both narrow and wide feet), soft silicone blades for training/perfecting bifin technique, and a price tag your wallet will love, you just can’t go wrong!

And the best part?

These bifins will be a staple item in your gear bag even if you go pro.

Just take a look at the top freedivers’ social media accounts - you’ll see that they do drills in the pool and at depth with the CORE Silicone Bifins to perfect their technique, and then use long bifins for their competition performances!

CORE Silicone Bifins Specs

Here are CORE Silicone Bifins specs at a glance:
  • Hypoallergenic and UV-resistant silicone
  • Designed for all water temperatures
  • Can withstand -30°C (-22°F) temperatures without deforming
  • Arch support maintains the correct position of your foot during the kick stroke for maximum efficiency
  • Open-heel foot pockets provide the optimal foot position for finning
  • The anatomical shape of the back strap is designed for a better fit over the Achilles tendon and offers maximum support
  • Eight blade rails with specific curvature profiles and stiffness distribution make the fins efficient and stable with the least amount of effort

When it’s Time to Upgrade

Once you feel like you’ve gotten the hang of the foundational bifin technique and want something a little more ‘oomph’ (and with no plans to join competitions), you’ve got two great options.

SPORT Bifins 3

SPORT Bifins 3 Fiberglass and SPORT Bifins 3 Carbon are truly ‘all-around’ bifins.

They give that extra dose of power that’s perfect for:
  • Recreational freedivers
  • Freediving instructors
  • Safety divers
  • Spearfishers
  • Underwater photographers
  • Etc.
The removable SPORT Silicone Foot Pockets come with a more spacious interior for a comfortable fit and are suitable for sub-max and max performances in training. They offer the same open-heel straps, anatomical back straps, and arch support as the CORE Silicone Bifin foot pockets, but with the added addition of rigid stabilizers on either side of the foot pocket to give you stability and control over each kick.

Plus, removable foot pockets means you can have 2 pairs of footpockets - one for when you need socks and one for bare feet - and swap them out effortlessly with different blades!

Fiberglass or carbon fiber blades?

Pick your poison when it comes to the blade - fiberglass for more durability or carbon fiber for a lightweight feel both in and out of the water. You can’t go wrong with either!
