Flat Feet and High Arches

The Mechanical Extremes: A Scientific Approach to Flat Feet and High Arches

The foot arch is nature’s "shock absorber." A healthy arch collapses slightly upon impact to absorb energy and becomes rigid during toe-off to provide propulsion. However, when the arch is too low (Flat Feet) or too high (High Arches), this delicate balance is disrupted, leading to a chain reaction of pain that can travel up to the knees, hips, and spine.

 

I. Flat Feet (Pes Planus): The Unsupported Chassis

  • Definition: The arch collapses, causing the entire sole to touch the ground. This is often accompanied by Overpronation (the ankles rolling inward).

  • Impact: Lack of support causes kinetic stress to shift to the knees and hips, frequently resulting in plantar fasciitis, shin splints, and chronic knee pain.

 

II. High Arches (Pes Cavus): The Failed Suspension

  • Definition: An abnormally high arch that does not descend even under weight-bearing. Pressure is heavily concentrated on the heel and the ball of the foot (metatarsal region).

  • Impact: High arches are too "rigid" and fail to shock-absorb. This leads to frequent ankle sprains, metatarsalgia (forefoot pain), corns, and even vibration-related spinal discomfort.

 

III. Aybroad’s Counter-Mechanical Solutions

As an insole manufacturer, we apply distinct engineering logics to balance these two extremes:

  1. For Flat Feet: Structural Reinforcement & Alignment

    • TPU Longitudinal Arch Support: We utilize high-rigidity materials to physically lift the collapsed medial arch, preventing fascia over-extension.

    • Deep Heel Cup: This feature locks the calcaneus in place, stopping inward ankle rotation and realigning the body’s mechanical axis.

  2. For High Arches: Total Contact & Shock Diffusion

    • Total Contact Contouring: Rather than a "hard push," our insoles fill the void beneath the arch to increase the surface contact area, effectively redistributing pressure away from the heel and forefoot.

    • Segmented Cushioning: Dual-layer cushioning (such as PORON® or Gel) is integrated into the forefoot and heel to compensate for the arch's natural lack of shock absorption.
