Dual-density composite for podiatric insoles —

Dual-density or triple-density layering for insoles is based on combining two or three layers of materials with distinct properties:
- Soft density: cushioning footbed, shock absorption, reduction of excessive pressure.
- Firm density: structural support, foot guidance, better weight distribution.
This architecture provides targeted cushioning while ensuring the stability necessary for postural corrections.

The choice of a composite for insoles must be based on several technical parameters:
- Shore A hardness: key to balancing comfort and support (soft = cushioning; firm = correction).
- Shape memory: essential for patients who use their feet intensively or require constant support.
- Compression resistance: guarantees durability over time, especially for heavier patients.
- Thickness: adaptation according to footwear (city, safety, sports, thin shoes).
- Ease of cutting: to save time in the workshop and achieve a clean finish.

The patient profile must be matched to the choice of density:
- Athletes: firm density + cushioning layer to absorb repeated impacts.
- Overweight individuals: high-resilience materials to prevent flattening.
- Children: intermediate densities, flexible but responsive, to support growth.
- Seniors: priority given to comfort, cushioning, and lightness.

Capron Podologie offers a wide range of dual-density composites suitable for all practices:
- EVA (ethylene vinyl acetate): this material offers an excellent compromise between cushioning and support, as well as very high crush resistance. It is ideal for athletes, active people, or heavy patients.
- PE (polyolefin): this material offers a wide range of densities and hardnesses. It is extremely stable and particularly suitable for overlays.
- Polyurethane (PU): a highly resilient material offering lasting comfort. It is ideal for prolonged standing or professional footwear.

By choosing Capron Podologie, you benefit from essential guarantees for your practice: a choice of adhesives compatible with the selected materials to prevent separation in multi-layer applications and designed for thermoforming, with immediate availability across a wide range of materials.
