The manufacture of a comfortable insole is strictly based on the selection of suitable materials. Polyurethane is the number one choice in such manufacture thanks to its light and durable texture, high slip resistance, and antibacterial features, which also allows the feet to breath by creating air circulation inside the shoes due to their porous spongy structure.

Kimpur has developed KIMfoot^® Fussbett Systems used in insole applications in order to increase shoe comfort.
