SHOE DESIGNING SUPPORT DEVICE THAT ESTIMATES IMPRESSION INDEX, AND SHOE DESIGNING SUPPORT METHOD THAT ESTIMATES IMPRESSION INDEX

A design element index input unit 10 inputs multiple design element indexes obtained by quantifying design in association with multiple portions constituting shoes. A learning unit 40 uses, as teacher data, pairs of multiple design element indexes and an impression index to learn correlations between multiple design element indexes and the impression index, and creates an impression estimation model. By means of a learned impression estimation model, an impression index estimation unit 60 estimates an impression index obtained by quantifying an impression of shoes, based on a set of multiple design element indexes that have been input. An output unit 70 outputs the estimated impression index.
