"The improved footpockets are a game changer. With more space for the toes and the new Comfort Lining I can wear these fins for hours."


- Vitomir Maričić, World Record Holder Dynamic Bifins

The Molchanovs Competition Bifins 2 (or Molchanovs CB2 for short) are a unique combination of our comfortable handbuilt open heel footpockets paired with the highest quality carbon fiber blades for the first time available in standard EU sizes or custom sizes. The Molchanovs CB2 comes with our new M-Stripe design in a variety of colors. Get one of our recommended standard configurations of color, flex and blade size or create your own Special Order.

The blades are designed and fine-tuned by Alexey Molchanov to decrease your energy consumption per kick without sacrificing speed. This is achieved with the unique "bottleneck" shape that allows the blade to transition quickly and efficiently between the stokes.

The curved shape of the footpockets and the built-in arch support keep your feet in the perfect position to maximize the use of the small muscles in the ankle and calf while minimizing drag. 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 with the new Comfort Lining and with more toe space inside the footpockets.
