Take steps towards a better posture. A good posture starts with the feet. The way in which the foot meets the ground affects the entire structure of the skeleton. The Therapeutic Posture Insoles ¾ help improve your posture by aligning the foot, ankle, knee, and hip to a healthy and correct position. The insoles are lightweight and shock-absorbing, with an orthopedic contoured silhouette to give your arches comfortable support. With their ¾ length, they fit in most types of shoes. The soles are lined with Iontex® which can benefit blood flow to the muscles.
