To realy measure falling shock to shoes.

A weight 10 is provided so as to freely slide up and down along perpendicular guides 2 and 2 erected on a floor 1. An acceleration sensor is provided on the upper surface of lower end part of the weight 10. A pedestal 14 is horizontally provided just under the weighty, and a piezoelectric sensor 15 is arranged on the upper surface of pedestal 14. On this piezoelectric sensor 15, a supporting stand 17 is provided as a dummy heel for supporting shoes 16 while turning their heel parts 16a upward. The outputs of acceleration sensor and piezoelectric sensor 15 are connected to an oscilloscope 24. The shoes 16 are inverted and placed on the supporting stand 17 rounded its top end, impact force is applied to the heel parts 16a of shoes 16 by pulling up the weight 10 to a prescribed height and next dropping it, and impact absorptivity is measured.
