PowerStep® PULSE® Air Insoles were designed by runners, for runners. Providing pain relief and prevention for the casual and the competitive, these running insoles feature a soft and springy layer of upgraded PORON cushioning. The PowerStep PULSE Air full length insoles offer the same support and cushioning as the popular PULSE Performance style, but with a resilient mesh top fabric that promotes air flow and creates a massaging effect with each step. The PULSE Air insoles have a unique design with a built-in neutral orthotic arch support and heel cradle that stabilizes the foot and improves alignment. This motion control along with targeted dual-layer cushioning helps absorb shock at impact to reduce stress on the feet, ankles, joints, and tendons. The PULSE Air running insoles provide the perfect blend of stability and cushioning during athletic activity to simultaneously increase comfort, help reduce fatigue and improve the efficiency of your stride.
