ABSTRACT:
A shoe such as a running shoe is disclosed which fits comfortably on the foot of the wearer during most times and which includes a sensor such as a bar movably attached to the shoe for increasing the tightness of the fit when the foot is moved relative to the lower leg in a plurality of directions from a normal position to positions relative in which greater forces are expected to be exerted by the user. Typically, the increase in forces is achieved by placing a movable insert in the shoe which is connected with the sensor via a cable. In a simplified form, the sensor is constructed so as to tighten a portion of the shoe against the foot to increase tightness of the fit.
