CBAS are supportive devices which are placed inside footwear to change the mechanical function and posture of the feet, knees, hips and back. They work dynamically during weight-bearing activities such as walking, running and standing. Ideally, they should provide full, custom and corrected arch contact so that the foot works in a biomechanically correct way.

To date, only the Foot Solutions Custom Biomechanical Arch Supports offer full-arch contact and accommodative support calibrated for your weight and foot type. The reason is simple. CBAS are more difficult to produce because they must change the way your foot works and be comfortable at the same time. Many other supports are either simply cushioned pads or give a small, inadequate arch support lacking individual customization to your foot. They may feel comfortable, but by failing to actually correct faulty foot mechanics, will not prevent the painful deformities or syndromes that much of the population commonly suffer from
