[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, posture problems, 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 calculated slope. The medial and lateral heel insoles provide stable support, cradle the heel, and help reduce foot fatigue associated with elevated height.[Adjustable Layers] These orthopedic heel wedges offer customizable correction with layers that can be used individually or combined. The top layer measures 0.45 inches in height, while the additional thinner layers measure 0.2 inches each. By adjusting the number of layers, users can gradually correct imbalances, improve gait mechanics, engage underused muscles, and enhance overall leg and body alignment during walking.
