Young women's perceptions of replaceable upper shoes before and after the upper interchange

This study tries to investigate the visual perception of casual and formal leather shoe uppers, by conducting semantic differential evaluations. Twelve upper design renderings were generated based on six ideations with casual uppers converted into formal leather uppers. Based on a seven-point Likert scale, twelve renderings were evaluated using fifteen Kansei adjective pairs and young women's willingness to purchase. Factor analyses were performed to analyze the differences and factors between casual and formal leather uppers. In the factor analysis of upper styles, five factors were identified for casual uppers: evaluation, attention, fashion, protection, and temperament; and five factors for formal leather uppers: attention, formality, fashion, weight, and protection. Whether a young woman is looking for formal leather uppers or casual shoe uppers, fashion plays a crucial role in her decision to purchase shoes.
