Size chart

The Molchanovs SPORT Bifins 3 Fiberglass - long bifins for freedivers who want high-quality fiberglass blades paired with standard-size SPORT Silicone Foot Pockets. Designed for freedivers who train, teach, and fun dive in the pool and open water. The fiberglass blades feature an updated blade layering pattern for more low-effort, high-propulsion finning. Anatomical silicone foot pockets make comfort a priority, along with rigid stabilizers for control over every kick and a unique energy transfer system for extra power in each movement.

Premium fiberglass blades
Premium 100% UHC fiberglass has been updated with an improved blade-layering process for low-effort and high-propulsion finning, making each movement you make an economical one. Now with an updated blade-layering process and size-graded stiffness to match blade length with resistance - soft blades are a little shorter for maneuverability and stiffer blades are longer for more balanced propulsion.

Anatomical foot pockets
Open-heel straps give you the freedom to flex your feet and fully extend your toes, while arch support keeps your feet in the optimal position for finning.

Rigid stabilizers
The stabilizers on each side of the foot pocket are thick and firmly enclose the blade and water rails, providing you stability and full control over each kick - regardless of ankle strength.

Innovative foot pocket attachment
The shape and attachment of the foot pocket to the blade creates a unique energy transfer system. With each kick, the silicone under the upper mounting plate compresses, sending an energetic transfer of force from foot to blade. The placement of the foot pocket also fixes your toes around the blade angle, streamlining every kick.

Easy assembly
Assembling the foot pockets to the blades takes only minutes, making it easier than ever to switch to a new pair of foot pockets or upgrade to a new blade.

Travel-friendly
Traveling with bifins becomes effortless, whether you want to tuck in the open heel strap to place into a case or fully disassemble the bifins and pack blades and foot pockets separately.

Minimalistic design
The new design is sporty and fierce while keeping the signature Molchanovs minimalism and style. Fiberglass blades are glossy black - choose from 6 bold accent colors.

SPORT Silicone Foot Pockets + SPORT Bifins 3 Fiberglass Blades

These instructions are for assembling the SPORT Silicone Foot Pockets to the SPORT Bifins 3 Fiberglass Blade.

Materials required for assembly

  • Molchanovs left and right fiberglass blades
  • Left and right SPORT Silicone Foot Pockets
  • 2 screws for each foot pocket (4 total)
  • Upper and lower mounting plates
  • Phillips head screwdriver

Assembly instructions

  1. Match the left and right foot pocket with the corresponding blade (marked on the back side of each blade).
  2. Insert the blade gently into the slot at the front of the foot pocket and through the side reinforcements, verifying it is inserted correctly and slides in smoothly without force.
  3. Align the blade by carefully adjusting its position until the blade’s mounting holes match with those on the foot pocket.
  4. Position the upper mounting plate over the toe section of the foot pocket, verifying it fits into the provided space.
  5. Begin hand-threading the screws into the holes of the lower mounting plate.
  6. Place the lower mounting plate over the blade, aligning it with the upper mounting plate and the holes. Tighten the screws in a clockwise direction using a Phillips head screwdriver with an even distribution of pressure.
  7. CAUTION: Secure the screws firmly, but avoid over-tightening which could strip the threads or damage the blade. Stop when you feel moderate resistance.

All equipment should be rinsed in fresh water after use and placed out of direct sunlight and heat. Do not place heavy objects on top of the blades and avoid placing the blades near sharp objects.
