Abstract
The present invention relates to a shoe midsole structure and a method for manufacturing the same. The shoe midsole has unique hollow particle units that may be additively manufactured without any support structure. Each of the hollow particle units has a specific thickness and a hollow interior. A housing layer of each of the hollow particle units has a plurality of openings, a plurality of planar annular portions surrounding each of the openings, and a plurality of curved portions connecting adjacent planar annular portions. The plurality of openings are disposed in pair on the housing layer symmetrically with respect to the geometric centroid of the hollow particle units. A plurality of hollow particle units are arranged into a multi-laminate structure in the shoe midsole. Some hollow particle units are bent when a compression force or a shearing force is applied during use.
