  • Publication number: 20070227042
    Abstract: A shoe has a recess portion on an upper side of an outsole, a sole touched surface layer on the upper side of the outsole, and a thermoplastic rubber for absorbing pressure and vibrating force on a wearer's foot so as to reduce the burden on the foot; the thermoplastic rubber is fitted in the recess portion of the outsole and covered by the sole touched surface layer, and an upper side thereof is formed with a concave and convex shape to fit a heel portion and an intermediate portion of a wearer's sole according to ergonomics; thus, that portion of the sole touched surface layer that is above the recess portion will have a concave and convex shape for fitting a heel portion and an intermediate portion of a wearer's sole; the thermoplastic rubber will reduce one-third to two-thirds of body weight pressure on the wearer's heel.

  • Publication number: 20070151124
    Abstract: A woman's shoe includes an insole surface layer, a sole under the insole surface layer and at least a thermoplastic rubber member. The sole is cut with at least a recess, for fitting the thermoplastic rubber member therein at a spot corresponding to a portion of a foot supporting a person's weight while walking or standing. Accordingly, the thermoplastic rubber member can absorb an impact force or a pressure as high as one third to two thirds of a body's weight while wearing such high-heel shoes. Moreover, it can soothe sourness of one's shoulders, soften the cervical vertebra and prevent insomnia, achieving a comfortable and healthy effect.
