When designing leather shoes, it is essential to consider factors such as material availability, cost, and performance characteristics, while also taking into account specific requirements based on product type and regional preferences. As of 2019, natural leather remains the ideal material for shoemaking; however, given China's limited supplies of cowhide and sheepskin-contrasted with its world-leading production of pigskin-there is significant potential for utilizing pigskin. Consequently, designers should actively explore and prioritize the creation of footwear using pigskin.
Furthermore, synthetic materials offer a glossy finish, vibrant colors, and excellent performance properties. Coupled with their low cost and abundant supply, they are already widely used for shoe uppers, and are increasingly being adopted for components such as insoles, heel counters, toe puffs, and outsoles.
