Three-point support mechanism: Our sports insoles feature professional support at the forefoot, arch, and heel to help correct walking and standing posture. Durable and comfortable: These insoles combine a biomechanical cushioning PU and gel base to help control excessive pronation, providing excellent shock absorption to relieve pain associated with plantar fasciitis, heel spurs, and knee pain. U-shaped deep heel cup: The shock-absorbing insole includes a U-shaped heel cup that stabilizes the heel, helps align the body, and evenly distributes pressure across the foot. Stay dry: The top layer is made of breathable, woven fiber mesh that keeps feet cool, dry, and odor-free during intense activity. Applicability: Insoles can be trimmed to fit your exact shoe size using the indicated cut lines. Suitable for shoe sizes 40 to 45. Ideal for sports, casual wear, workouts, hiking, basketball, tennis, skiing, and golf.
