What is the hardness requirement of EVA block used for carving insoles?

EVA block for carving insoles

The hardness requirement of EVA (ethylene-vinyl acetate) block used for carving insoles can vary depending on individual needs and preferences. However, generally speaking, the hardness of EVA blocks used for carving insoles is measured using the Shore A or Shore C durometer scale.

For carving insoles, a commonly used hardness range falls between 25 to 55 on the Shore A scale. Softer EVA blocks with lower Shore A readings (e.g., 25-35) provide more cushioning and shock absorption, which can be beneficial for individuals seeking greater comfort. On the other hand, harder EVA blocks with higher Shore A readings (e.g., 45-55) offer more stability and support.

It’s important to note that the optimal hardness of the EVA block for carving insoles may depend on various factors, including the specific foot condition, body weight, activity level, and personal preferences. Therefore, it is recommended to consult with a podiatrist, orthopedic specialist, or a professional experienced in custom orthotics to determine the most appropriate hardness for your individual needs. They will evaluate your foot structure and provide personalized recommendations to ensure the best outcome.
