Cetma s-WiNG Freediving Footpockets

Cetma s-WiNG Freediving Footpockets

• Revolutionary rubber blend: high elasticity & thermoplastic hardness
• "Foot on Carbon" design: extended blade portion underfoot for better load transfer
• Sky-boot like structure: high stiffness bands for firm foot hold & power
• High stiffness sole: prevents deformation, increases blade efficiency by ~30%
• Open Flow System: tendon-less design for optimized hydrodynamics
• Twinzer System: vertical stabilizers reduce sideslip, channel water
• Anti-Twist System: U-shape reinforcement stabilizes blade

The Cetma Composites s-WiNG footpockets represent a significant advancement in freediving fin technology, engineered for maximum efficiency and comfort. Crafted from an innovative rubber blend (1.05 g/cm³ density) that combines the elasticity of natural rubber with the durability of thermoplastic, these footpockets are virtually weightless in water. The "Foot on Carbon" design allows a longer portion of the blade (especially Cetma blades) to sit directly under the foot, improving load transfer and comfort by up to 60% compared to conventional designs. A "Sky-boot like" internal structure with high-stiffness bands ensures the foot is firmly constrained, minimizing energy dissipation from rubber deformation. The high-stiffness sole prevents warping under load and is compatible with various blades, enhancing their efficiency. The "Open Flow System" ditches traditional side tendons to optimize hydrodynamics by channeling water alongside the foot. Further enhancing stability, the "Twinzer System" incorporates vertical stabilizers to reduce sideslip, while the "Anti-Twist System" uses U-shaped reinforcement to prevent blade rotation. Available in 7 sizes (35-48) for an anatomical fit, and featuring Cetma's Hi-Efficiency water rails, these footpockets are ideal for competitive freedivers and serious spearfishermen seeking peak performance.
