[ Correction & Protection ] Adjustable Heel Wedge Inserts can help relieve knee pain and foot discomfort caused by improper walking posture. These heel inserts are designed for individuals with bow legs, knee pain, foot alignment issues, osteoarthritis, knock knees, supination, pronation, posture problems, and other conditions related to uneven foot alignment. [ Cupped Heel Support ] These supination and pronation heel wedge inserts are shaped to fit the natural curve of the heel, based on scientifically measured angles. The medial and lateral heel insoles provide stable support, cradle the heel, and help reduce foot fatigue caused by wearing elevated shoes. [ Adjustable Layers ] These orthopedic heel wedges for supination and pronation correction can be used individually or layered together, allowing you to customize the height and angle. The top layer measures 0.45", while the thinner layers measure 0.2". This layered design helps correct imbalances in leg rotation, adjust walking mechanics, and engage underused muscles to improve overall posture, leg alignment, and gait.
