  • FIG. 4C the shoe of the first embodiment of the present invention. It is when the foot and toes dorsiflex and the toes (and thus the pressure sensors) come into contact with a backside surface of the upper 3 that the pressure sensors detect loads. The stronger the toes press against the backside surface of the upper 3 , the greater the peak values of the loads get. The longer the toes get in contact with the backside surface of the upper 3 , the longer the loads act.
  • the toe pressing member 4 is formed of non-stretchable (or high rigidity) material, the toe pressing member 4 hardly stretches. Thereby, it turned out that the toe pressing member 4 presses against the toes (and thus the pressure sensors) and the peak values of the loads thus tend to appear readily. It also turned out that in the case of the toe pressing member 4 formed of material of greater hardness, the toe pressing member 4 is hard and pushes back strongly against the toes and the peak values of the loads thus tend to appear readily at the time of dorsal flexion of the toes.
  • the toe pressing member 4 is enclosed by the upper 3 formed of stretchable material, when the toes bear on the toe pressing member 4 from the backside surface of the upper 3 at the time of dorsal flexion of the toes, the upper regions around the toe pressing member 4 stretch and thus the toes easily dorsiflex. Thereby, the state of dorsal flexion of the toes is easily maintained.
  • the toes can readily sense dorsal flexion with free dorsal flexion motion of the toes maintained.
  • tibialis anterior muscle is muscle that extends from the outside of the tibia to the inside of the instep and that acts at the time of dorsal flexion motion of the foot and the toes.
  • an electrode was attached to a position corresponding to tibialis anterior muscle of the leg of the subject and then myogenic potential of tibialis anterior muscle of the subject during running test was measured.
  • the running test was conducted at 10 km/hour.
  • FIG. 5A to 5B show electromyogram of tibialis during the running test.
  • FIG. 5A indicates the case in which the subject ran with bare feet
  • FIG. 5B the case in which the subject ran with the embodiment's shoes on, respectively.
  • the vertical axis depicts myogenic potential and in the horizontal axis, “0” shows ground contact point, “0.3” toe-off point and near “0.1” foot-lifted period before ground contact.
  • occurrence of myogenic potential indicates that tibialis anterior muscle moved.
  • FIG. 5A As can be seen by comparing FIG. 5A with FIG. 5B , in the phase of dorsal flexion of the foot and toes from the foot-lifted period before ground contact (near 0.1 in the horizontal axis) to the ground contact point (0 in the horizontal axis), the value of myogenic potential in FIG. 5 B (ran with the shoes on) is greater than that in FIG. 5A (ran with bare feet). Therefore, when integrating the values of myogenic potential in this dorsal flexion phase, the integrated value in FIG. 5B is greater than that in FIG. 5A . In such a manner, a greater integrated value of myogenic potential indicates that muscular movement was more active.
  • the toe pressing member 4 formed of non-stretchable material presses against the toes (or the distal end portions thereof) from above.
  • the shoe wearer can recognize that the toes of the foot came in contact with the upper 3 and realize that dorsal flexion motion of the foot was made properly.
  • the shoe wearer can activate movements of the foot and toes.
  • the toe pressing member 4 is formed of material of greater hardness (of stiffness) than the upper 3 , when the toes have come into contact with the upper at dorsal flexion of the foot, the toe pressing member 4 presses against the toes strongly from above because the toe pressing member 4 is hard (or hardly stretch). Thereby, the shoe wearer can recognize that the toes of the foot contacted the upper 3 and realize that dorsal flexion motion of the foot was made properly. As a result, the shoe wearer can activate movements of the foot and toes.
  • the outer perimeter of the toe pressing member 4 is encompassed by the stretchable upper 3 , when the toes of the foot have come into contact with the upper 3 at dorsal flexion of the foot, the upper region around the toe pressing member 4 stretches. Thereby, the upper 3 does not impede dorsal flexion motion of the foot and toes and thus contact time of the toes with the upper 3 becomes longer. As a result of this, dorsal flexion motion of the foot can be promoted and the toe pressing member 4 can be prevented from imparting more pressure than is needed to the toes of the foot.
  • each of the press parts 41 - 45 composing the toe pressing member 4 are interconnected with each other through the connecting parts 40 , when each of the toes comes into contact with the upper 3 at dorsal flexion of the foot, the extent of stretch of the upper region around each of the press parts 41 - 45 can be restrained, thus regulating pressure from the toe pressing member 4 to each toe of the foot at a greater value.

  • the connecting portions 40 may be omitted and each of the press parts 41 - 45 may be provided discretely.
  • each of the press parts 41 - 45 of the toe pressing portion 4 is surrounded by the stretchable upper 3 . Therefore, when each of the toes comes into contact with the upper 3 at the time of dorsal flexion of the foot, each upper region around each of the press parts 41 - 45 can stretch independently each other. As a result, dorsal flexion motion of each of the toes can be further promoted.
