Good arch orthopedic insole needs to have a good supporting effect and pressure is not deformed. Orthopedic also need to have resilience to protect the plantar fascia, so as to effectively support the arch, thereby reducing fatigue and soreness. The three-point mechanics effective arch support is designed according to the human body structure principle, reducing the over-stretching of the plantar fascia, increasing the stress area of the plantar to balance the forefoot heel pressure, strengthening the compact wrapping of the foot and reducing the instability of the movement. Shaking, slipping. The sacral latex gasket supports the humerus, the plantar flexion and cushioning, relieves the pressure of the patella and toe joints and improves the tibia reaction speed.
