Improved, ultra-responsive fiberglass fins, created with the same material as the Molchanovs CM3 monofin. Paired with the upgraded Molchanovs hand-built foot pockets, available in standard EU sizes or custom-sized to your desired fit with an open heel for unparalleled ankle flexibility.
The fibreglass bifins 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.
Molchanovs Handbuilt Footpockets
The curved shape of the footpockets and the built-in arch support keep your feet in a streamlined position ready for the kick while minimizing the drag. They allow your feet to create an immediate response in the fin once the movement begins. The arch support also decreases fatigue in your feet that is normally arising from flattening our feet. The new generation of handbuilt footpockets provides more comfort for your feet than ever before due to the comfort lining and more space for your toes inside the footpockets. The new design is highly UV-resistant and will stay bright and shiny.
Standard size foot pockets
|EU Size||Foot length (cm)|
Notes: The EU foot pocket size will typically give a comfort to normal fit without socks (meaning the fins should remain comfortable for long periods of time). If you want a tight fit without socks, it may be necessary to go a size down. If you are wearing socks and want a comfort fit, it may be necessary to go up a size.
If you intend to wear socks, please make all measurements with socks on.

The desired fit determines the tightness of the foot pockets. 3 options are available:
Comfort: Ideal for recreational dives and long training sessions. If you intend to put them on for long periods of time, choose this option. Comfortable for about 45-60 min.
Normal: A medium tightness, ideal for focused training sessions and competitions. Comfortable for about 20-30 min.
Sport: The tightest fit available, maximising power transfer, specially for competition dives. Comfortable for about 10-15 min.
The blades are made to withstand strong underwater moves in any direction and consequently provide powerful thrust. However, don’t walk with the fins on rough rocks and don’t drop heavy solid objects, such as cameras with underwater gear, weights, etc. – the blade could crack or break. We suggest washing off salt and keeping the fins away from the strong sun and heat.
