Definitions

  • the present invention relates generally to footwear, and more particularly, to a multi-function shoe pad.
  • the feature of each lies in that the shoe pad includes one or more rigid solid protrusions corresponding to specific positions of a human foot sole, like toe section, internal arch-foot section, or transverse-arch section, for allowing the shoe pad to conform to human feet ergonomics for average distribution of pressure applied to the feet, thus maintaining body balance, correcting standing posture, and relieving sore feet resulting from long standing.
  • the primary objective of the present invention is to provide a multi-function shoe pad, which is skidproof and can cause air convection.
  • the secondary objective of the present invention is to provide a multi-function shoe pad, which remind and alert the user to correct his or her standing posture.
  • Another objective of the present invention is to provide a multi-function shoe pad, which can enhance resilience and shock absorption.
  • the multi-function shoe pad having a main body. Structurally corresponding to respective portions of the user's sole, the main body is composed of a foot arch portion, a heel portion located behind the foot arch portion, a toe portion located before the foot arch portion and corresponding to the user's first, second, third, fourth, and fifth toes, and a metatarsus portion located between the foot arch portion and the toe portion.
  • the foot arch portion includes an internal foot-arch portion and an external foot-arch portion.
  • the toe portion includes an internal toe portion corresponding to the first toe and an external toe portion corresponding to the other toes of the user's foot.

  • the first air groove 131 has an arc-shaped aperture 102 located adjacent to the front peripheral edge 101 and recessed inwardly. The aperture 102 prevents the peripheral edge of the main body 10 from tightly clinging to the internal wall of the shoe to increase the amount of exhaust of hot air and suction of the cold air.
  • the first chamber15 When the shoe pad 1' is actually used, as the heel portion 14 is forced, the first chamber15 can be squeezed under the compressed state; meanwhile, the hot air inside the first chamber 15 can be squeezed out through the first air groove 131. On the contrary, when the first bulge 111 is jostinated because no more external force is applied thereto, the first chamber 15 is under the uncompressed state and the cold air inside the shoe can be sucked into the first chamber 15 through the first air groove 131. In this way, the efficiency of the cyclic air convection between the shoe pad 1' and the inside of the shoe can be enhanced via the air groove.
