The Spenco PolySorb Heavy Duty Insoles are engineered for individuals who demand maximum support and durability from their footwear. Whether you are navigating rugged outdoor terrain or standing on hard industrial floors for long hours, these performance foam inserts provide the necessary cushioning to prevent foot fatigue. The core of the insole features a proprietary SpenCore layer, a five-thirty-second inch shock-absorbing material that softens heel impact and reduces strain across the entire foot. Unlike rigid orthotics, these insoles utilize lightweight PolySorb Polyurethane foam to offer flexible, contoured support that adapts to your natural stride. This design is particularly beneficial for workers, hikers, and athletes in India who require consistent energy return and stability. To ensure a healthy foot environment, the top layer is finished with a four-way stretch fabric treated with Silpure antimicrobial technology. This combination effectively manages moisture, prevents painful friction blisters, and inhibits the growth of odor-causing bacteria, keeping your shoes fresh throughout the day.
