Shock Doctor Men's / Women's Active Impact Insoles cradle your feet with premium shock absorption and support technology These insoles are just right for anyone who spends a lot of time on their feet—whether you're walking, running, playing sports or standing all day at work. ShockDome technology in the heel, midfoot and forefoot areas lives up to its name, absorbing the shock of each step, so you feel less impact on your lower body. Full-length shock-absorbing foam adds extra comfort from heel to toe. A lightweight support shell and Butterfly Control Bar under the heel support the foot, helping to control pronation (foot rolling inward) for a more stable, balanced stride. Airflow channels and an AIR/FX antimicrobial cover work together to help maintain a cool, dry, fresh foot environment.
