Corrects alignment and protects posture: adjustable heel wedge inserts help prevent knee pain and foot deformities caused by improper gait. They address common alignment issues such as bow legs, knock knees, pronation, osteoarthritis, and other misalignments, promoting the correct foot position for enhanced comfort and support. Ergonomic heel support: medial and lateral heel inserts provide stable support, reduce foot fatigue, and help the feet sit in proper alignment for a secure, comfortable fit. Adjustable height and correction: the system uses stacked layers. The top layer is 1.1 cm high; each additional thinner layer is 0.5 cm. You can adjust the height and correction level to retrain muscles and gradually improve gait over time. Pain relief and stability: by redistributing pressure and correcting foot alignment, these inserts help reduce symptoms associated with misalignment and provide relief for conditions such as supination and pronation. Compatibility: designed to fit in most shoes that accommodate orthotic inserts. Use scenarios: - Daily wear during long days of standing or walking, especially for overpronation or uneven gait. - Athletic activities such as walking or hiking where stable foot alignment supports comfort and performance. - Rehabilitation and ongoing gait correction to retrain movement patterns over time.
