Unique half-hand design: effectively corrects foot lowering while allowing flexible walking. The forefoot can bend without hindering the movement of the metatarsal bones, increasing stability and enabling rehabilitation to be carried out scientifically and efficiently. High density resin skeleton: one-piece molding with a curved profile using PE material. The design offers toughness and strong cold resistance, adapts to ergonomics and the calf curve for a better correction fit. It includes an inner pad to protect the contact position and reduce discomfort. Asymmetrical design concept: central design of the orthosis is on the medial side. This facilitates controlled outer valgus strength during adjustment, strengthens the stability of the inner splint, and aids in correcting varus symptoms. Four-level adjustable tension: provides stronger correction to meet rehabilitation needs at all stages and helps avoid frequent replacement of the foot lifter orthosis. Use scenarios - Post-injury or post-surgical rehabilitation where progressive correction is required and four-level tension can be adjusted to match the rehabilitation stage. - Daily walking and moderate activities that require stable support without restricting natural foot movement. - Physical therapy or sports training settings where controlled correction and stability are needed while performing dynamic activities.
