The present invention relates to the production of lower extremity supportive products, including boot, shoes, sandals, leg braces, etc. One embodiment of the present invention relates to a method for providing a three-dimensionally customized lower extremity product. The method includes measuring and recording data related to a three-dimensional representation of a customer's lower extremities in an activity-specific optimal stance. The three-dimensional representation includes specific anatomical position information including extensions, flexions, rotations, inversions, eversions, etc. The three-dimensional representation also includes surface information including foot shape, ankle shape, sole shape, etc. The measurement and recordation is performed at a convenient location such as in close proximity to the customer's residence or at an airport terminal. The customized lower extremity product is then manufactured at an independent location. The manufactured customized lower extremity product is customized according to the data so as to support the customer's lower extremity in the activity-specific optimal stance. In addition, the customized lower extremity product may be delivered to a location that facilitates customer pickup.
