• Description

  Tailor your monofin specifically to your build, strength, and diving technique with the PRO Monofin 4 Fiberglass - the most customizable fiberglass monofin on the market. Customization options include blade and accent color, blade size, blade stiffness, and the choice between standard-sized or customized footpocket 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 design features the double M-stripe, now on both ends of the blade, with a slightly longer and smoothed-out silhouette for additional leverage. Additionally, optimized inserts are now placed into footpockets 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 footpocket angle is set at 30° and the blade-layering structure has been updated to support this low-effort, almost straight leg technique by keeping the load on the ankles. The medium-hard and hard stiffnesses will be more powerful and engage more of the quads and torso.

  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.

  • 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

  Molchanovs 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.
