1. Usage Time: The nylon brace is designed and manufactured to be worn for about 1.5 hours daily in the first two weeks, primarily to allow the legs to adapt, establish wearing habits, and gradually increase tightening intensity. After adjustment, wear it for no less than 30 minutes per session, ideally around 2 hours daily. Physical correction is a longterm investment, with effects appearing gradually over a cycle of 23 months. 2. Two Types: There are two types available. Choose the adult model for heights above 1.5 meters and the children's model for heights under 1.5 meters. It is comfortable and breathable, featuring upgraded replacement straps and scientifically designed correction. 3. 3in1 Design: It includes a fullbody thigh strap, knee strap, and calf strap, all widened and thickened to avoid replacement. The large area ensures comprehensive coverage. 4. Removable: It is equipped with builtin long aluminum strips on both sides to conform to leg contours, concentrating force on the sides of the legs. The aluminum sheet pad is removable.
