Description

The present invention pays attention to the weight of the soles during walking and exercises that make complex movements, and in order to improve exercise performance, the center of gravity is smoothly moved to have a function that matches the purpose of use. It relates to insoles that can be used.

  Traditionally, shoe insoles have functions such as breathability, antibacterial, deodorant, shock absorption, comfortable fit, arch support, flex, rebound, among others, breathability, antibacterial, deodorant, shock absorption Such functions are emphasized.

  In addition, a shoe sole, a midsole attached to a shoe, and a cup insole have been proposed that employ a structure in which materials having different hardness or rigidity are partially arranged as shown below.

  For example, Japanese Utility Model Laid-Open No. 3-79704 discloses a shoe in which the hardness of the elastic body at the toe portion with which the toes of the insole are in contact is lower than the hardness of the elastic body at the stepping portion (Patent Document 1). ).

  Japanese Patent Laid-Open No. 2001-61509 discloses that an insole board is divided into a distal end portion mainly composed of a toe portion, an intermediate portion mainly composed of a stepping portion, a non-stepped portion and a proximal end portion mainly composed of a heel portion. Disclosed is an insole board split-type shoe sole structure in which the front end and the base end are formed from a relatively hard material and the middle is formed from a flexible material having a lower hardness. (Patent Document 2).

  Japanese Patent Application Laid-Open No. 2003-289903 has a soft elastic part and a second elastic part having higher bending rigidity than the soft elastic part, and the second elastic part covers a lower region of the foot's heel. A midsole and a cup insole disposed in the region are disclosed (Patent Document 3).
