Your arch shape should determine which insole is best for you. Neutral arches tend to cause mild prontation - foot and ankles roll slightly inward, placing pressure on big toe and inside of foot. Neutral arches need firm, yet flexible arch support for shock absorption and proper alignment. The PowerStep Pinnacle, with built-in neutral arch support and two layers of plush cushioning, is the perfect balance of comfort and support. Featuring the signature Powerstep arch shape, these insoles crale 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 netural arch support shell, and cushioning, the Powerstep Pinnacle is a trusted solution to improve foot function, decrease arch pain, and help alleviate common foot condition typically caused by mild pronation.
