[Correction & Protection] Adjustable Heel Wedge Inserts help relieve knee pain and foot discomfort caused by improper walking posture. These heel inserts are designed to support individuals with bow legs, knee pain, foot alignment issues, osteoarthritis, knock knees, bowleggedness, pronation, supination, and other conditions related to uneven foot alignment. [Cupped Heel Support] These supination and pronation heel wedge inserts are engineered to match the natural curvature of the human heel, featuring a scientifically designed slope. The medial and lateral heel insoles provide secure fit and stable support, cradling the heel and helping reduce foot fatigue associated with elevated height. [Adjustable Layers] These orthopedic heel wedges feature multiple layers that can be used individually or combined to achieve the desired lift. The top layer measures 0.45 inches, while the additional thinner layers measure 0.2 inches each. Gradual height adjustment helps balance muscle strength, encourage proper alignment, and promote more natural walking mechanics, supporting improved posture and lower limb function.
