Shoe insole

A shoe insole comprising:

• a sheet section configured to be arrangeable onto an entire base of a shoe, the sheet section being formed of a soft synthetic resin, the sheet section including a toe section formed such that the toes of a foot can be disposed therein, a bulged section formed such that tips of metatarsal bones at which the width of the foot protrudes farthest to the left and right can be disposed therein, an arch section formed such that a section of the foot from the metatarsal bones to directly below the lateral malleolus can be disposed therein, and a heel section formed such that a section of the foot from directly below the lateral malleolus to the heel bone rearward of the lateral malleolus can be disposed therein;
• and
• a support plate that is adhered to a bottom surface of the arch section and the heel section of the sheet section, and that is formed from a material which is formed of a hard resin,
• wherein the sheet section comprises in the arch section:
• an inner wall section curved in an arch shape in a longitudinal direction with an end section standing upward smoothly such that at least a first metatarsal bone can be disposed therein;
• an outer wall section curved in an arch shape in the longitudinal direction with an end section standing upward smoothly such that at least a fifth metatarsal bone can be disposed therein;
• a central wall section formed between the inner wall section and the outer wall section,
• wherein the support plate comprises in a support plate arch section:
• a support plate inner wall section, which corresponds to the inner wall section of the sheet section, curved in an arch shape in the longitudinal direction with an end section standing upward smoothly such that at least the first metatarsal bone can be disposed therein;
• a support plate outer wall section, which corresponds to the outer wall section of the sheet section, curved in an arch shape in the longitudinal direction with an end section standing upward smoothly such that at least the fifth metatarsal bone can be disposed therein;
• a support plate central wall section, which corresponds to the central wall section of the sheet section, formed between the support plate inner wall section and the support plate outer wall section,
• the support plate comprising an inner ridge formed on a boundary between the support plate inner wall section and the support plate central wall section, and an outer ridge formed on a boundary between the support plate outer wall section and the central wall section,
• wherein the inner ridge, which protrudes from the bottom surface of a central rear wall section, is formed as a solid band shape within the support plate arch section and is curved in an arch shape in the longitudinal direction,
• wherein the outer ridge, which protrudes from the bottom surface of the central rear wall section, is formed as a solid band shape within the support plate arch section and is curved in an arch shape in the longitudinal direction,
• an entirety of the inner ridge is entirely spaced apart from an entirety of the outer ridge such that the inner ridge and the outer ridge are not directly connected to each other,
• a plurality of through-holes, spaced apart and arranged along the longitudinal direction, are formed in both the inner wall section and the outer wall section of the support plate, where protrusions formed on the bottom surface side of the inner wall section and the outer wall section of the sheet section can fit therein without any gaps,
• an upper surface and a bottom surface of the support plate central wall section located between the inner ridge and the outer ridge is curved so as to draw an arch in the longitudinal direction,
• the sheet section comprises an extension section that protrudes upward so as configured to oppose, from a side surface, the heel section configured to be located directly below the lateral malleolus and/or the arch section, and
• the support plate comprises a support plate extension section that protrudes upward so as configured to oppose, from a side surface, the heel section configured to be located directly below the lateral malleolus and/or the arch section.
