The next generation in our record-breaking monofin line.
The PRO Monofin 4 Fiberglass is the next generation in our line of record-breaking monofins. With a new captivating design, optimized stiffness inserts that give you more “spring” in your kick and better energy transition, and your choice of customizations, you’ve never been more ready to explore new depths.

Tailor your monofin specifically to your build, strength, and diving technique with the PRO Monofin 4 Fiberglass - the most customizable fiberglass monofin in our range of monofins. Customization options include blade and accent color, blade size, blade stiffness, and the choice between standard-sized or customized foot pocket size, fit, and angle.

The PRO Monofin 4 Fiberglass features a durable fiberglass blade that is in the top-performance range for both fiberglass and carbon blades overall. The captivating new blade design features double-lined blade accents, now on both ends of the blade, with a smoothed-out silhouette. Additionally, optimized inserts are now placed into foot pockets according to blade stiffness, giving them a more ‘spring-like’ effect for better transition of energy from the feet to the blade.

The soft and medium stiffness options of the PRO Monofin 4 Fiberglass are ideal for freedivers who use an ankle-driven technique that focuses on both a strong front and back kick. The blade-layering structure has been updated to support this low-effort, almost straight leg technique by keeping the load on the ankles. The standard foot pocket angle is set at 30° but can be customized depending on the flexibility of your ankles.

For a full guide on each customization option and to understand what is right for you, see the ‘Size and Customization Guide’ section below.

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: 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 Monofin 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, 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 Monofin Blade Size
We also offer the choice of a Small monofin blade for freedivers who are under 65kg (143lb), shorter than 170cm (5 feet 6 inches), or with shorter leg proportions. Small blades are 2cm (0.8in) shorter than Regular blades in length and width, and 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.

If you are on the smaller and lighter side (or if you prefer a more agile monofin), choose a Small blade. If you are on the taller or heavier side (or if you prefer a more powerful monofin), choose a Regular blade.

Choosing Foot Pocket Angle
The standard 30° foot pocket angle will emphasize the back kick. If you have very flexible ankles, we recommend you choose a 25° foot pocket 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 monofins take approximately 5 - 6 weeks depending on the volume of orders. Standard monofin orders may be ready to be shipped as soon as you order depending on availability.
