Abstract: The purpose of this study is to use the self-developed collection system to study the relationship between the attention and conversion rate of female sandals in offline smart stores and the basic elements of women's shoes.One more accurate direction for improving Look-to-Buy rate of female sandals in offline smart stores can be set up. In this study, the attention data of different types of female sandals in eight offline smart stores of a certain domestic shoe brand from June to August 2018 had been collected, and had been also analyzed with the Optimal Scaling Model by combining various factors such as product, price and sales. Our results showed that the key factors affecting the attention conversion rate of summer female sandals were the upper material, color, heel and style of shoes, ranked in order of importance. But the attention conversion rate of summer female sandals is not obviously correlated with the price. Therefore, we can assume that the upper material is particularly important for the attention and attention conversion rate of female sandals products, and innovating sandals material is an important means to improve attention, and then improve Look-to-Buy rate.
