Force sensing methods, systems, and computer-program products may be used to sense pressure at a plurality of points of a user's foot, including its bones, joints, muscles, tendons, and ligaments. Such systems, methods, and computer-program products sense pressure along the bottom of a user's foot during sports training and monitoring applications, electronic games, and diagnostic systems. In particular, the system generally comprises a transducer having a plurality of points of interest, an insole node for collecting and transmitting data sensed at the plurality of points of interest, first means for coupling that data across a network, by way of second means for coupling same to a collector node, and then to a computer.
