1. A footwear system, comprising:
two separate foot sensor subsystems each carried by a shoe of a subject and each comprising:
at least one force sensor configured to measure a force at at least one predetermined anatomical location on a foot, and
footwear electronics coupled to the at least one force sensor,
wherein each foot sensor subsystem is operatively coupled with a computing device;
the footwear system further comprising a non-volatile memory that carries programming instructions, which, when executed, cause the foot sensor subsystem to:
(a) define subject's weight based at least in part on a weight distribution across a foot, a total weight applied to the foot, and a partial weight applied to the foot;
(b) transfer the subject's weight data to the computing device;
(c) activate the computing device in response to the subject's weight data;
(d) establish an initial sensor state based on the subject's weight data; and
(e) reduce tampering with the computing device by:
activating at least one foot sensor subsystem by the footwear electronics based on the subject's weight data corresponding to the initial sensor state, and
not activating the at least one foot sensor subsystem by the footwear electronics based on the subject's weight data lacking correspondence with the initial sensor state.
