This project report summarizes material selection and process selection for running shoe soles. For the insole, ethylene vinyl acetate (EVA) was selected as the best material due to its flexibility, strength, biocompatibility, and low cost. For the outsole, carbon black reinforced styrene butadiene rubber was chosen as it offers stiffness, strength, fracture toughness, low density and cost. Molding was identified as the preferred process for manufacturing both parts due to its suitability for the selected materials and lower costs for small and large batch production runs.
