Freediving Fins X-Wing Apnea M EU 36-37-UK 3-4-USA 4-5 Mares 420416MED036

Description:

The Mares X-Wing Apnea freediving fins are purpose-built long-blade fins engineered for breath-hold diving and demanding rocky environments. The blade is manufactured from pre-impregnated fiberglass layers with variable thickness and a parabolic deflection profile to deliver powerful, efficient thrust while limiting leg fatigue. At 69.3 cm long and 19.0 cm wide, the extended blade and 30° blade-to-foot-pocket inclination maximize propulsion on a medium kick width. Variable-height side profiles and a medium-stiff blade (M) optimize flexibility, channel thrust and control, while the durable construction stands up to contact with rocks and boulders. The comfortable foot pocket is designed to be worn with or without socks, and the blade is interchangeable for easy maintenance or customization. A blue polygon design improves visibility and recognition at depth.

Key Features:

• Blade made from pre-impregnated fiberglass layers for consistent strength and response
• Variable-thickness blade with high-performance parabolic deflection for efficient energy transfer
• Blade dimensions: 69.3 cm length × 19.0 cm width — one of Mares’ longer, high-thrust designs
• Medium-stiff blade (M) tuned for balanced power and reduced fatigue on medium kick width
• 30° blade inclination from the foot pocket to optimize stroke mechanics
• Variable-height side profiles that support flexibility and create a channel-thrust effect
• Durable construction rated for use in rocky and boulder-strewn environments
• Comfortable ergonomic foot pocket designed to be worn with or without neoprene socks/booties
• Interchangeable blade for easy replacement or upgrade
• Blue polygon blade graphics for improved underwater visibility

Recommended Use:

Ideal for serious freedivers and advanced recreational apnea athletes who need maximum propulsion and efficient kicking on long dives. Best suited to open-water freediving, depth training and hunting in environments where durable fins and powerful strokes are required — including rocky bottoms and boulder fields. Perform best with a medium kick cadence and can be used with thin neoprene socks or bare feet depending on comfort; blade interchangeability allows easy maintenance or stiffness changes to match diver weight and technique.
