PowerStep® PULSE® Performance 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 ShockAbsorb Premium Foam cushioning over the entire insole-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 Performance 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.
