1. Unique half palm design: effectively corrects foot height. Allows flexible walking without hindering foot movement, with a bendable forefoot that doesn't restrict metatarsal motion, enhancing stability and enabling scientific, efficient rehabilitation. 2. density resin frame: Onepiece molding with a curved design, made of PE material for toughness and strong cold resistance. Ergonomically conforms to the calf curve for a better corrective fit, featuring inner padding to protect contact areas and reduce discomfort. 3. Asymmetrical design concept: The orthosis's central design is positioned on the medial side, making it easier to control external valgus adjustment strength. This enhances the internal orthosis's stability and aids in correcting varus symptoms. 4. 4level adjustable tension: Strengthens correction to meet rehabilitation needs at all stages, avoiding frequent replacement of the foot lifter orthosis.
