Abstract: A flat-to-heel convertible outsole allows a user to transition from a flat-bottom, low-wedge shoe style to a high-heel shoe style. A collapsible heel includes an upper heel, a lower heel, and a heel pin. The upper heal is connected to an arch platform in order to form a single foot supporting structure. The heel pin is hingedly connected to the upper heel, while the lower heel is telescopically connected to the heel pin opposite the upper heel. In this way, the lower heel can be positioned in an extended configuration or a stowed configuration. When in the extended configuration, a locking mechanism connected to the lower heel engages a lock notch of the upper heel in order to secure the lower heel to the upper heel. When in the stowed configuration, the lower heel is positioned within a heel recess that traverses into the arch platform.
