Bifins CS1 with Custom Foot Pockets

Regular price $755.00
World-record setting carbon bifins, used by the best freedivers around. Custom foot pockets with open heel for unparalleled ankle flexibility.

We are proud to offer our new, top of the line carbon bifins - the Molchanovs Bifins CS1 with Custom Foot Pockets.

We start out making our 100% carbon fiber Molchanovs C1 Blades by hand and using a vacuum infusion. Even though it is a more expensive and time-consuming process it produces a higher carbon fiber-to-resin ratio in a thinner, lighter, and more responsive blade. This result is a blade with an amazing feel yet is powerful enough to set multiple world records.

We then marry these blades to our custom sport foot pockets. Our customization process takes into account key measurement points of your feet, to ensure that they fit your feet snugly. The open heel is designed for maximum agility while ensuring optimum energy transfer for the conservation of energy.

The result is the best performing bifins available anywhere!

Care instructions: rinse your fins under fresh water after pool or saltwater sessions to prevent a buildup of chlorine or salt crystals. Please note that custom products are made to order and take 4-6 weeks to be delivered.
