Abstract: Aiming at the problems of women's poor foot fitness and low comfort during pregnancy, this article developed and designed a kind of shoes suitable for pregnant women's physiological characteristics. Based on the characteristics of physiological changes of women during pregnancy, the characteristics of foot deformation of pregnant women and the information about the need for wearing shoes were extracted by literature research and in-depth interview. The Kano model, combined with the Better-Worse coefficient and sensitivity calculation analysis method, was used to categorize and prioritize the requirements. The FBS model was used as a framework to map the key needs of "function-behavior-structure" and obtain the design scheme of pregnant women's footwear. The Kano-FBS model-based footwear design for women during pregnancy addressed the issues of low comfort and poor foot fitness caused by the morphological changes in pregnant women's feet, and could serve as a reference for the development and design of footwear products.
