A rotatable traction pad for a shoe can be mounted in a circular cavity in the shoe sole bottom surface, with the cavity being relatively shallow in relation to the shoe sole thickness. The pad mounting mechanism can include an annular bearing housing adhesively bonded to the circular side surface of the cavity, and an anti-friction bearing carried within the annular housing. The traction pad includes a rigid central post that extends upwardly through the bearing.

A shape measuring apparatus according to claim 8, wherein each of the first and second angles is about 45°. 10. A shape measuring apparatus according to claim 8, wherein each probe includes a third position-measuring plane mirror for measuring a position of the probe in the Z-axis, wherein said third measuring instrument includes a third reference plane mirror having a normal in the Z-axis direction, and measures a separation between said third position-measuring plane mirror and the third reference plane mirror. 11. A shape measuring apparatus according to claim 10, wherein said probe includes: a position-measuring mirror block provided with the first and second position-measuring plane mirrors; a contact ball that is attached to a tip of the position-measuring mirror block, and contacts the object; and a probe shaft provided at a rear end of said position-measuring mirror block, the third reference plane mirror being formed at a rear end surface of said position-measuring mirror block. 12. A shape measuring apparatus according to claim 11, wherein said probe shaft has a hollow part, through which said third measuring instrument measures the separation between said third position-measuring plane mirror and the third reference plane mirror. 13. A shape measuring method for measuring a surface shape of an object on an XYZ-axis coordinate, said method comprising the steps of: holding a plurality of probes in a Y-direction using a guide means that allows each of the plurality of probes to be movable in a Z-axis direction, each probe being connected to a balance means for adjusting a contact force between each probe and an object by balancing each probe's own weight; moving, in the Z-axis direction, the plurality of probes arranged in the Y-axis direction, while bringing each probe into contact with the object; measuring contact position between each probe and the object in X-axis and Y-axis directions using first and second measuring instruments; measuring a contact position of each probe in the Z-axis direction using a third measuring instrument; moving the plurality of probes in the X-axis direction relative to the object; repetitively measuring contact positions of each probe in the X-axis, Y-axis, and Z-axis directions using the first, second and third measuring instruments; and calculating the surface shape of the object based on contact positions in the X-axis, Y-axis, and Z-axis directions measured by the first, second and third measuring instruments. 14. A shape measuring method according to claim 13, wherein the first and second measuring instrument additionally measure inclinations of each probe in rotating directions around the X-axis and Y-axis, so as to correct the surface shape of the object to be calculated. 15. A shape measuring method according to claim 14, wherein the first and second measuring instruments measure the inclinations of the probe in the rotating directions around the X-axis and Y-axis by measuring a plurality of points of the probes in the Z-axis direction. 16. A shape measuring method according to claim 14, wherein each of the first and second angles is about 45°. 17. A shape measuring method according to claim 14, wherein the probe includes a third position-measuring plane mirror for measuring a position of the probe in the Z-axis, wherei
