C4 Anatomical Insoles for Freediving and Spearfishing
The C4 anatomical insoles are specifically designed for freediving and spearfishing users, with special attention to shape, design, and materials to improve comfort and performance in the water.
The anatomical structure of the insoles helps reduce empty spaces inside the foot pockets, often caused by the symmetrical shape of the right and left foot. Without dedicated insoles, these spaces can lead to reduced fit and heat loss.
Technical Features and Benefits
- Comfort and fit: the insoles help support the plantar arch, ensuring a precise, stable fit inside the foot pocket and reducing fatigue during finning.
- Improved finning control: the better fit allows more efficient transfer of propulsive force, optimizing thrust and fin responsiveness during freediving.
- Thermal insulation: reducing empty spaces limits the flow of cold water, keeping the foot at a more stable temperature and reducing the risk of muscle cramps in the water.
- Compatibility: perfectly adaptable to C4 foot pockets and suitable for use with most foot pockets on the market, thanks to the option to trim them along predefined lines.
Size Specifications
The C4 insoles are available in three size ranges, covering a wide range of usable Sizes:
- 38-41
- 41-43
- 44-47
The insole can be shaped along the pre-marked cutting line to achieve a custom size and optimal fit inside the foot pocket.
Insole for Gara Modular Fins
The Gara Modular insoles are designed to improve thrust transmission and optimize the fit of any fin or foot pocket, especially when the fit is too roomy.
Made from fully recycled semi-rigid material, they provide a good balance of stiffness and comfort, contributing to improved finning efficiency during freediving and spearfishing.
The insole is compatible with foot pockets from size 38 to 47 and can be precisely adjusted thanks to the pre-printed guide lines, which make it easy to trim to three different sizes for an optimal fit.
This insole is recommended for use with thin socks in temperate waters, improving thrust transmission without compromising sensitivity and comfort in the water.
- Semi-rigid recycled material for mechanical strength and environmental sustainability
- Adjustable to sizes from 38 to 47 via guided trimming
- Supplied as a pair for right and left foot
- Optimizes fit in fins with thin socks
Replacement Insoles for Freediving Foot Pockets
The insole is the internal component of the foot pocket that supports the foot in the plantar area. Its presence reduces empty space inside the foot pocket, improving foot stability during movement, and can optimize the fit in foot pockets with a generous internal volume relative to the foot size. This category includes two insole models sold separately, compatible with foot pockets from different brands and trimmable to size.
Compatibility and Use
Both models can be trimmed to size using pre-printed guide lines on the insole, eliminating the need for an exact size. The stated compatibility covers foot pockets from size 38 to 47 for both products. C4 insoles are primarily intended for C4 foot pockets but can be adapted to other foot pockets on the market. Cressi Gara Modular insoles are stated to be compatible with any foot pocket or fin. Use with thin neoprene socks is the intended condition for Cressi insoles, where they improve finning power transfer by compensating for the reduced grip of the foot inside the foot pocket.
