Freediving Fins X-Wing Apnea Soft EU 38-39-UK 5-6-USA 6-7 Mares 420416SFT038

Description: The Mares X-Wing Apnea Soft freediving fins are high-performance long blades engineered specifically for apnea and freediving. The blade is constructed from pre-impregnated fiberglass layers with variable thickness, delivering a parabolic deflection profile that maximizes thrust while keeping kick effort efficient. At 69.3 cm long and 19.0 cm wide, this model provides exceptional propulsion and is one of the longest blades in the Mares range, optimized for a medium kick amplitude. A 30° inclination from the foot pocket and variable-height side profiles focus and channel water flow for powerful, efficient strokes. The ergonomically shaped foot pocket offers high comfort and is designed to be worn with or without socks; the soft blade option included with this SKU reduces leg fatigue for lighter divers. The robust build and reinforced manufacturing make these fins suitable for demanding environments, including rocky and boulder-strewn shore entries. The blade is interchangeable for serviceability and customization.
