Structure of platform shoe

Abstract

A platform shoe includes an upper, a midsole, and an outsole. The upper is attached to the midsole and has a wearing opening. The midsole is attached to the outsole and includes a midsole bed and a front pad. The midsole bed has a posterior portion that is recessed to form a first trough. The front pad is mounted to an anterior portion of the midsole bed and is recessed to form a second trough and a third trough. The outsole includes a supportive section, a bottom section, and a shoe heel. The supportive section has a posterior portion to which the shoe heel is fixed. The bottom section is provided at an underside of the supportive section and the shoe heel. The bottom section has an anterior portion on which the bottom platform is formed. The troughs each receive and retain therein a corresponding soft pad.

I claim: 
     
         1 . A structure of a platform shoe comprising at least an upper, a midsole, and an outsole;
 the upper being attached to the midsole, the upper comprising at least a wearing opening;   the midsole being mounted to the outsole, the midsole comprising a midsole bed and a front pad, the midsole bed having a posterior portion that is recessed to form a first trough, the front pad being mounted to an anterior portion of the midsole bed, the front pad being recessed to form a second trough and a third trough; and   the outsole comprising a supportive section, a bottom section, and a shoe heel, the supportive section having a posterior portion to which the shoe heel is fixed, the bottom section being provided at an underside of the supportive section and the shoe heel, the bottom section having an anterior portion on which a bottom platform is formed.   
     
     
         2 . The structure of the platform shoe according to  claim 1 , wherein the supportive section comprises a support member made of a metal or a composite material mounted therein. 
     
     
         3 . The structure of the platform shoe according to  claim 1 , wherein the first trough is formed on the midsole bed of the midsole and located at a shoe heel portion of the outsole, the first trough being formed in the midsole in such a way as to extend in an axial direction of the midsole bed of the midsole, the first trough being a concave trough having a central part that is relatively deep and a circumferential part that is relatively shallow. 
     
     
         4 . The structure of the platform shoe according to  claim 1 , wherein the second trough is formed on the front pad of the midsole and located at a shoe palm portion of the outsole, the second trough being formed in the midsole in such a way as to extend in a transverse direction of the midsole, the second trough being a concave trough having a central part that is relatively deep and a circumferential part that is relatively shallow. 
     
     
         5 . The structure of the platform shoe according to  claim 1 , wherein the third trough is formed on the front pad of the midsole and located at a shoe toe portion of the outsole, the third trough being formed in the midsole in such a way as to extend in a transverse direction of the midsole, the third trough being a concave trough having a central part that is relatively deep and a circumferential part that is relatively shallow. 
     
     
         6 . The structure of the platform shoe according to  claim 1 , wherein the midsole comprises a plurality of insertion holes formed in a back side thereof, the insertion holes being separately located in a portion between the first trough and the second trough, the outsole comprising insertion pins formed thereon in such a way that the insertion pins respectively correspond to the insertion holes of the midsole, whereby the insertion pins of the outsole are insertable into the insertion holes of the midsole. 
     
     
         7 . The structure of the platform shoe according to  claim 6 , wherein the insertion pins are formed on the supportive section of the outsole. 
     
     
         8 . The structure of the platform shoe according to  claim 1 , wherein the midsole comprises a first rush stop site, a second rush stop site, and a third rush stop site, the first rush stop site being formed in an anterior end of the first trough, the second rush stop site being formed in an anterior end of the second trough, the third rush stop site being formed in an anterior end of the third trough, whereby the first rush stop site is located in front of the heel of a foot wearing the shoe, the second rush stop site is located in front of a foot sole of the foot, and the third rush stop site is located in front of toes of the foot. 
     
     
         9 . The structure of the platform shoe according to  claim 2 , wherein the supportive section is provided, in a posterior end thereof, with a plurality of fixing holes and the shoe heel comprises a plurality of fixing elements arranged therein in such a way that the fixing holes respectively correspond to the fixing elements, so that threaded fasteners are receivable through the fixing holes and the fixing elements to fix the shoe heel to the supportive section, the fixing elements being expansion bolts. 
     
     
         10 . The structure of the platform shoe according to  claim 9 , wherein the supportive section has an anterior end having a configuration having projecting opposite sides and a concave central portion so that the anterior end of the supportive section forms a first projecting section and a second projecting section, the supportive section with the anterior end being thickened from the central portion towards the first projecting section and the second projecting section, whereby the first projecting section and the second projecting section and an anterior end section of the support member collectively form a triangular kinematic support by which a medial longitudinal arch, a lateral longitudinal arch, and an anterior transverse arch of a foot wearing the shoe are supported.
