Abstract
A midsole of footwear with an incorporated orthotic support. The midsole includes a soft and flexible member and a more rigid orthotic support. The orthotic support includes a heel cup and an arch support portion that extends forwardly from the heel cup. Embodiments produce the midsole by positioning the orthotic insert between an upper portion of the footwear and an outsole. Then, soft and flexible material is injected into the space surrounding the orthotic. The soft and flexible material subsequently cures forming the multi-part unitary midsole.
