One could use two bathroom scales next to each other and surround them by rulers on the floor next to them on four sides then take pictures with a camera to look at the distribution of weight of a person standing with one foot on each scale.

The scales could be calibrated by placing an equal weight on the center of each scale and seeing if they give the same number.  One should also check if placing the exact same amount of weight on different parts (coordinates) of the same scale gives the same reading for weight.

Coordinates may not be exact due to the distance and angles from the point of view of the picture and the rulers being at a distance from the foot but this is much cheaper than buying force plates and a multiple camera system.  It might be possible to use the camera to take a picture that captures a view of both the weight measured on the scales and the position of the feet.  Another option might be to simply write measurements down.
