P-Cell is recommended material for diabetic top covers primarily because it is a closed cell material. Closed cell materials are advantageous for diabetic footwear as they offer excellent cushioning and support while also being resistant to moisture and bacteria. This feature is particularly important for individuals with diabetes, as they are more susceptible to foot ulcers and infections. The closed cell structure helps to maintain a dry environment, reducing the risk of skin breakdown and promoting overall foot health.

While insulation, lightweight properties, and biodegradability may be beneficial attributes in certain contexts, they do not specifically address the primary concerns of moisture management, shock absorption, and protection that are critical for diabetic patients. Therefore, the characteristic of being a closed cell material makes P-Cell particularly suitable for the unique needs of individuals with diabetes regarding foot care and footwear.
