High density resin skeleton: one-piece molded construction with a curved profile. Made from PE material for strong toughness and cold resistance. Ergonomic fit adapts to the calf contour for a correction-friendly profile, protects contact points and reduces discomfort. Four level adjustable tension: The foot lift orthosis supports four levels of correction. This allows stronger correction to meet rehabilitation requirements at all stages and helps avoid frequent replacement of the orthosis. Convenience: Easy to install in shoes with a snug fit. Designed to relieve ankle plantar fas fasciitis, ankle injuries, goutfoot, Achilles tendonitis, heel spurs, heel disease, and similar conditions. Unique half-hand design: Effectively corrects foot drop. Enables flexible walking without hindering foot activities. The forefoot can bend and does not restrict metatarsal movement, increasing stability and enabling scientifically guided rehabilitation. Use scenarios: - Daily wear in shoes during work or at home to relieve plantar fasciitis and provide ankle support. - Rehabilitation walking to correct foot drop and improve gait without restricting movement. - Outdoor activities or sports where stable support for the ankle and heel regions is beneficial, helping with recovery while maintaining normal activity.
