Specialized orthotic insoles designed to correct X-shaped legs (genu valgum) and foot eversion, addressing inner sole wear and 'inner八字' (in-toe gait) issues. Featuring a precise 'high inside, low outside' arch support structure—1.3cm elevation at the medial longitudinal arch and 0.4cm drop at both lateral edges—to realign foot posture, reduce excessive pronation, and redistribute pressure evenly across the foot. The top layer uses textured gray fabric for breathability and slip resistance, while the bright yellow EVA base provides cushioning and durability. Ideal for daily wear, walking, light sports, or office use where prolonged standing is required. Helps prevent knee, hip, and lower back strain caused by poor foot alignment. Suitable for men and women seeking non-invasive biomechanical correction without surgery or custom orthotics. Easy to insert into most casual shoes, sneakers, or dress shoes with removable insoles.
