The Spenco Ground Control Full-Length Athletic Insoles for Women and Men are ideal for active endeavors and athletic footwear. Available in three arch heights—low, medium, and high—for optimized support. A decoupled heel separates the heel and arch support, reducing pronation. Cushioned heel pads absorb shock during each foot strike. An energy-return polymer zone works with the foot, not against it, maximizing performance. The Spenco Ground Control Full-Length Athletic Insoles for Women and Men have an anti-slip textured nylon top fabric, treated with Silpure for odor resistance.
