Abstract: Modular shoe systems include an upper, an outsole attached to the upper, and several midsole inserts. Each midsole insert is positionable in overlying relationship with the outsole and can operatively engage the outsole to form an assembled shoe. The outsole can include a receptacle, such as a depression or opening, configured to receive a protrusion in the midsole insert. Multiple midsole pieces can be cooperatively engaged to form the midsole insert. The midsole pieces are selected based on their properties and the needs of the user. Methods for customizing a shoe include selecting a midsole insert based on a property and positioning the midsole insert in overlying relationship with the outsole to operatively engage the midsole insert and outsole. The midsole insert can be removed and a different midsole insert can be selected and positioned based on another property. The midsole insert(s) can be assembled using several midsole pieces.
