Abstract
According to embodiments of the invention, a precursor sheet is formed by injecting an EVA-based material into a mold cavity. The mold cavity is configured to create a series of indentations through a first portion of the precursor sheet and into a second portion of the precursor sheet. The precursor sheet is removed from the mold cavity and the second portion of the precursor sheet is removed from the first portion of the precursor sheet to create an isolated sheet with a series of through-holes. The isolated sheet is then formed into a portion of a shoe.
