What is a common material used in the fabrication of custom orthotics?

EVA (ethylene-vinyl acetate) is a popular material used in the fabrication of custom orthotics due to its unique combination of properties. This thermoplastic polymer is known for its flexibility, durability, and shock-absorbing qualities, making it an excellent choice for cushioning in orthotic devices. Its ability to be easily molded and shaped allows for customization to fit the specific contours of an individual's foot, which is crucial for providing both support and comfort.

Additionally, EVA has good impact resistance and is lightweight, which benefits patients who require orthotic support without adding significant bulk or weight to their footwear. It's also relatively easy to clean and maintain, contributing to its usability over time. These features make EVA particularly suited for a variety of orthotic applications, including insoles and foot supports for a range of foot conditions.
