| This research aimed to propose modeling process development for customized woman midsole design based-on 3D Printing technology. To accomplish the objective, we suggested design factors of customized midsole, and presented the optimized foot size, process of midsole modeling. Also, using 3D printed midsole, we performed fit test. Necessary design factors of customized midsole were foot length, ball width and foot arch. Optimized foot size was derived by adding and subtracting based on foot length, ball width. we gave a spare space from end of foot length and subtracted the 6% on ball width. For increasing the comfort of midsole, we took a picture with inner/outer foot side surface and applied to modeling. In order to evaluate the validity of suggested process, we printed a midsole using 3D printer, and conducted usability test to the subjects. The subjects are three women in their 20s, who are wearing a Korean female average foot size of 235~240mm by using the simple random sampling method. Then, subjects stood on the customized midsole and we measured the peak and average plantar pressure, based on the left foot. As a result, the maximum value of peak pressure found on the heel regions. And the peak pressure of heel regions was slightly lower compared to subject`s normal midsole. This result showed that suggested customized midsole modeling process can reduce the high plantar pressure on the heel regions by redistributing the pressure. This finding can be used as a basis for further research of customized shoes making. |
