PROBLEM TO BE SOLVED: To tactually, auditorily, and visually bring an ON/OFF output signal of an electric signal into line with a gravity center position physically felt by vibration sound when turning on/off dome springs of an insole sheet by foot pressure varying by movement of a user.SOLUTION: By applying, to the center of a head top part of a dome spring 15, indirect foot pressure obtained by converting direct foot pressure applied to the dome spring 15 into up-and-down motion of one point by repetition of conical flexure and restoration of a vibration resonance plate 10, a footwear base can detect a prescribed pressure range of foot pressure increase/decrease as an electric signal of ON and OFF. |
