Design updates to the blade include a unique bottleneck shape, resulting in the blades feeling smoother than ever before with a more powerful reaction due to their efficient transition in the water. Other updates include improved layering of the fiberglass, using a “wave” layering structure that allows for smooth transition and even stiffness between the layers. This creates a more efficient and responsive movement throughout a kick cycle. They also come in the new M-stripe design in four vivid colors.
Our CB2 Fiberglass are of the same standard as most carbon fins on the market, making them an ideal choice for freedivers who desire quality but are not in the market for carbon fins.
We took customer feedback and focused on making the new generation of Molchanovs hand-built foot pockets even more comfortable than before. Updated Comfort Lining and increased space for the toes give your feet some much-needed relief, even with the tightest fit. They are also UV-resistant and heavy-duty, and have built-in arch support that decreases fatigue and keeps the foot in the perfect position, maximizing small-muscle use and minimizing drag.
Molchanovs hand-built foot pockets are available in standard EU sizes and custom sizes.

Care Instructions
All equipment should be rinsed in fresh water after use and placed out of direct sunlight and heat. Do not place heavy objects on top of the fins. For more information, see how to care for your freediving bifins and monofin here. Additionally, see how to travel with your bifins and monofin here.
Warranty Policy
A 1-year limited warranty applies. Please note that defects or damage to the equipment caused by improper or incorrect use or insufficient/improper maintenance and product care will render our Warranty Policy null and void.
Standard Molchanovs Hand-Built Foot Pocket Sizing
Please note: If you have a noticeable size difference between each foot, wider feet, or especially high or low arches, we suggest ordering custom foot pockets. Follow the ‘Custom Hand-Built Foot Pocket Measurement Guide’ guide below to measure your feet correctly.

Custom Foot Pocket Fit Guide
The desired fit determines the tightness of the foot pockets. Three options are available:
Comfortable: Allows more space inside of the foot pockets for the feet. The feet will feel like they are on the verge of movement, but will not actually have movement since any friction between the feet and foot pockets will cause blisters. Comfortable for about 2 hours of wear.
Normal: More comfortable compared to the Tight fit. There is slightly more space inside for the feet, but not enough space for extra movement. Allows for about 20 - 50 minutes of wear.
Tight: Specifically designed for performance, which means that the fit is especially tight. This gives you the best control over the blade as the feet are very compressed with no space for any extra movement inside of the foot pocket. Suitable for about 10 - 30 minutes of wear.
Please note: The maximum time a freediver can wear foot pockets (especially Tight fit) depends on their level of experience and how flexible their feet are. If you would like to improve your foot flexibility, watch this video.
Choosing Bifin Blade Stiffness
Blade stiffness depends on your height, weight, technique, experience, training goals, and blade size. Below are general tips on how to choose the right stiffness. If you are not sure, e-mail info@molchanovs.com with a video attached of one of your dives for a recommendation.
Soft: Suitable for smaller and lighter freedivers with less body strength and for experienced freedivers with excellent ankle-driven technique. If a freediver has more lower-body strength, they can choose a medium stiffness. Soft blades are more economic in terms of energy consumption, but require good ankle-driven technique to be effective.
Medium: Suitable for larger and heavier freedivers, freedivers with more lower-body strength, or freedivers who need more power. Freedivers who are heavier and have not trained to use ankle-driven technique should choose medium stiffness with a quad-driven technique.
Hard: Suitable for larger and heavier freedivers or freedivers with a lot of lower-body strength who want more speed and propulsion and are willing to use more energy consumption per kick. Hard blades require less frequency and more amplitude.
Production time for bifins take approximately 4 - 6 weeks* depending on the volume of orders. If you need them sooner, write to us at info@molchanovs.com and we will check to see if we can accommodate your needs.
*Generally, production time is 4 - 6 weeks for customized bifins. However, the production time is currently 10 - 12 weeks due to the large number of orders. We are working to increase our production capacity and production times will soon return back to normal.
