3mm Poron Insole Sheet

Poron Shock-Absorbing Foam Sheet – 3 mm 

As we age, the natural cushioning in our feet gradually reduces, making each step more impactful. This effect, often called “step shock”, can send vibrations up through the legs and spine, causing discomfort in the feet, knees, hips and back — and in some cases contributing to headaches. Step shock is especially common among those with arthritis, diabetes or sensitive feet.

Poron polyurethane foam provides outstanding shock and impact absorption. Its high-density composition enhances the foot’s natural cushioning, reducing stress on joints and improving overall walking comfort. This makes Poron one of the most effective materials available for protecting the feet from repetitive impact.

Poron sheets can be used to make custom insoles or to modify existing ones, helping to relieve unwanted pressure areas and improve overall comfort. They can also be used to deflect pressure against the calves when wearing ski boots or other snug footwear.
