Product description of C4 400 Footpocket

Description summary

Experience unparalleled freediving and spearfishing with C4 400 Footpockets. Weighing just 390 grams, they are the lightest thermoplastic rubber footpockets available, drastically reducing leg fatigue for longer, more enjoyable dives. Their ergonomic design offers a secure, comfortable fit that maximizes energy transfer to your fin blades, ensuring superior propulsion. The integrated 3-degree anatomical angle optimizes your kicking motion for enhanced efficiency and reduced joint stress. Sold as a single unit, adapter mounting kit not included. Perfect for all C4 blades designed for 300 and 400 footpockets

Discover the pinnacle of freediving and spearfishing innovation with the C4 400 Footpocket. Engineered for discerning divers who demand ultimate performance and comfort, this footpocket represents a new standard in underwater propulsion systems. Elevate your diving experience with a design that prioritizes lightness, efficiency, and ergonomic perfection.

We’re particularly proud of the new 400 foot pockets. They are manufactured in thermoplastic rubber and thanks to their unique design they only weigh 390 grams. This makes the 400 the lightest thermoplastic rubber foot pockets on the market today. This incredible reduction in weight is not just a number; it translates into a tangible decrease in leg fatigue and energy expenditure. You´ll experience longer, more enjoyable dives with less strain, allowing you to focus on your underwater adventure. The reduced inertia means quicker, more responsive finning and enhanced agility for precise maneuvering in any condition.

The ergonomic design is a hallmark of the C4 style, and the 400 footpocket is a testament to this philosophy. It has been meticulously shaped to provide a secure, comfortable, and highly responsive fit that feels like a natural extension of your foot. This superior connection eliminates uncomfortable pressure points and prevents energy loss, ensuring that every ounce of your effort is transferred directly to the fin blade for maximum propulsion.

A standout feature is the pre-formed 3-degree angle integrated into the footpocket´s design. This anatomical inclination is crucial for enhancing both comfort and efficiency. It aligns the blade with your natural kicking motion, optimizing the power transfer throughout the entire finning cycle. This leads to a smoother, more powerful kick with less stress on your ankles and joints, significantly boosting your overall performance and endurance in the water. Whether you´re ascending from a deep dive or covering distance on the surface, you´ll feel the immediate benefit of this advanced biomechanical design.

Important Information:

This product is sold as a single unit: Foot Pocket 400 without Adapter mounting Kit (1 unit). Please be aware that the assembling kit is not included and must be acquired separately to mount your fin blades.
