Tailor your monofin specifically to your build, strength, and diving technique with the PRO Monofin 4 Fiberglass - the most customizable fiberglass monofin in our range of monofins. Customization options include blade and accent color, blade size, blade stiffness, and the choice between standard-sized or customized foot pocket 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 blade design features double-lined blade accents, now on both ends of the blade, with a smoothed-out silhouette. Additionally, optimized inserts are now placed into foot pockets 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 blade-layering structure has been updated to support this low-effort, almost straight leg technique by keeping the load on the ankles. The standard foot pocket angle is set at 30° but can be customized depending on the flexibility of your ankles.
