The monofin foot pocket you love on your favorite bifin blade.
We took the monofin foot pocket you love and attached it to carbon blades to create the PRO Hyper Bifins Carbon. Designed specifically for freediving athletes who use a more quad-driven technique with a strong front kick and less focus on the back kick, allowing you to put more load on your hip muscles. Customize your bifins to your quad-driven technique and rediscover your limits.
The PRO Hyper Bifins Carbon are our most customizable bifins ever with the addition of our ‘hyper’ monofin foot pockets, named after Andronov’s hyperboloid for the monofin-specific construction created in the 2000s by Evgeniy Andronov. Personalize your blade and accent color, blade size, blade stiffness, and choose between standard-sized or customized foot pocket size, fit, and angle.
These ‘hyper’ foot pockets are the foot pockets we use on our monofins. They contain the same comfortable micropore lining inside and optional arch support as our lighter bifins foot pockets. Differences include an additional amount of rubber to build this new form and a 30° angle attachment to the blade to help you perform a stronger back kick. Additionally, the foot pockets have more of a ‘spring-like’ effect due to the additional volume of rubber and optimized stiffness of fiberglass inserts in the foot pockets. These features give you more distance with each kick and a better transition of energy from the feet to the blade.
The PRO Hyper Bifins Carbon feature a lightweight and responsive carbon blade, giving extra propulsion to your kick, along with a slight adjustment to the blade layers and shape to support this new foot pocket type. The soft and medium stiffness options are ideal for freedivers who use an ankle-driven technique that focuses on an efficient front and back kick. The medium-hard and hard stiffnesses will be more powerful and engage the quads more. Available in 6 bold accent colors.

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 Sizing’ 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 that 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 firstname.lastname@example.org with a video attached of one of your dives for a recommendation.
Soft: Suitable for smaller and lighter freedivers, and also for experienced freedivers with excellent ankle-driven technique. Softer blades are more economic in terms of energy consumption, although it mostly remains a preference among freedivers with more strength whether to choose a soft or medium stiffness.
Medium: Suitable for larger and heavier freedivers, freedivers with more lower-body strength, or for freedivers who needs more power.
Choosing Bifin Blade Size We also offer the choice of a Small bifin blade for freedivers who are under 65kg (143lb), shorter than 170cm (5 feet 11 inches), or with shorter leg proportions. Small blades feature 10% less surface area than Regular blades and an adjusted ‘bottleneck’ shape. They are particularly ideal for shorter freedivers because of their ease of maneuverability while additionally requiring less power and energy spent on kicks. While the blade-layering structure of both Small and Regular blades are the same, the reduced surface area of the Small blade can make them feel softer than Regular blades.
Choosing Foot Pocket Angle The standard 30° footpocket angle will emphasize the back kick. If you have very flexible ankles, we recommend you choose a 25° footpocket angle to balance the load between the ankles and hips. For stiffer, less flexible ankles, choose a 35° angle.
Production Times Production time for customized bifins takes approximately 4 - 6 weeks depending on the volume of orders.* Standard bifin configurations may be ready to be shipped as soon as you order depending on availability.
*The usual production time of bifins is 4 - 6 weeks, however, due to a recent high volume of orders, production times have been temporarily increased to 10 - 12 weeks. We are currently working to increase our production capacity and appreciate your understanding.
