Shock Doctor's low-profile cleat insole is specifically engineered to reduce the stress on athletes' feet and lower body. The results are quicker movements, more confidence, and stability, even on uneven surfaces. The insole is 3mm thin so it fits into narrow cleats, weighing under 1.6 ounces. But that doesn't mean it gave up the cushioning. An adaptive arch flexes vertically and horizontally to adapt to any foot shape, using its bio-mechanical design for ultimate shock absorption. Full-length foam reduces joint fatigue and the resulting pain to keep you training longer. A lightweight support cap and heel ShockDome™ absorb shocks that can transfer to your knees, hips, and back. The ShockDome continues into the midfoot to relax the body and is designed to help relieve Plantar Fascitis.
