Shock absorbing materials are essential components in prosthetic, orthotic, and orthopedic footwear fabrication, designed to reduce impact forces, improve comfort, and protect sensitive areas of the body during walking and standing. These materials are used to cushion pressure points, absorb ground reaction forces, and enhance energy distribution, helping to improve patient comfort while reducing the risk of pain, skin breakdown, and joint stress.
In prosthetics and orthotics, shock absorbing materials are commonly used in foot orthotics, prosthetic feet, socket interfaces, heel cushions, and orthopedic insoles. They are especially important for patients with diabetes, arthritis, limb loss, or neurological conditions, where pressure management and vibration reduction are critical for safe mobility.
These materials are available in a wide range of densities, hardness levels, and thicknesses, allowing technicians to select the correct combination of cushioning and support for each clinical application. Common materials include EVA, polyurethane foams, rubber compounds, microcellular sheets, silicone, and specialty orthopedic materials such as Poron®, Nora®, and PPT®.
Shock absorbing sheets can be easily cut, milled, thermoformed, or laminated, making them suitable for both traditional fabrication methods and modern CAD/CAM workflows.
