Dr. Scholl's Prevent Pain protective insoles are designed for those who have had prior episodes of daily pain and want to stop it from reoccurring, or want to be proactive and help stop pain from occurring in the future. The new Prevent Pain insoles are scientifically designed and clinically proven to reduce the leading cause of pain in key lower body joints—your foot, knee and lower back from reoccurring. Dr. Scholl's Prevent Pain Insoles prevent pain from muscle-induced joint stiffness and strain caused by conditions or activities like recent reduction in activity or weight gain, flat feet, overpronation, over-supination, bad posture, heavy or uneven pressure, and working, walking, or running on hard surfaces.
