Disclosed are several examples of a ground reaction force sensor for an article having an upper force plate for contacting the article, a lower force plate for contacting the ground, a vertical load cell disposed between the plates for measuring the force acting on the cell in a direction that is substantially perpendicular to the surface, a horizontal load cell disposed between the plates for measuring the force acting on the cell in a direction that is substantially parallel to the surface, and with the load cells being mounted between the plates in a configuration that is substantially insensitive to off-axis forces imposed on them for improved load cell measurement accuracies. Various other features and benefits are provided.
