Your arch shape should determine which insole is best for you. Low arches tend to cause overpronation -- foot and ankles roll inward, placing pressure on bigger toes and inside of foot. Low arches need slight arch support and cushioning to control motion and alleviate pressure. The PowerStep® Pinnacle Low, with built-in low arch support and two layers of plush cushioning, is the perfect balance of comfort and support. Featuring the signature PowerStep® arch shape, these insoles cradle the arch and heel, adding stability and motion control, to control excess stress on joints and tendons. By combining the PowerStep® clinically-proven arch shape, semi-rigid low arch support shell, and cushioning, the PowerStep® Pinnacle Low is a trusted solution to improve foot function, decrease arch pain, and help alleviate common foot conditions typically caused by overpronation.
