The PowerStep® Pinnacle High full-length insoles are designed for those with high arches and a rigid foot structure. They deliver two layers of plush cushioning is the perfect balance of comfort and support. Feet with high arches need arch support and cushioning to reduce excess pressure on the ball and heel of the foot. Feet with high arches cause supination, where the feet under-pronate, placing pressure on the smaller toes and outside of the foot. By combining premium cushioning and the clinically proven PowerStep arch shape in a semi-rigid high arch support shell, the PowerStep Pinnacle High replacement insoles help to decrease arch pain and help alleviate common foot conditions typically caused by supination. These are made in the USA. Please refer to the size chart for sizing guidance.
