Shoe sole structure of a cycling shoe for bicycles

Abstract

A shoe sole structure of a cycling shoe for bicycles has a sole and an insole. The sole is made of rigid materials without deforming, and has at least one engaging hole, and at least one ventilating hole. The insole is made of soft materials, abuts against a top surface of the sole. When the insole is deposited in the cycling shoe and abuts the sole, and the user's foot wears the cycling shoe and the weight of the user's foot is applied on the insole and the sole of the cycling sole, since the material of the insole is softer than the material of the sole to enable the insole to deform, and the weight of the user's foot is pressed on the insole, and the insole completely abuts the user's foot and the sole without forming any interspaces between the user's foot and the sole.

What is claimed is: 
     
         1 . A shoe sole structure of a cycling shoe for bicycles comprising:
 a sole being made of rigid materials without deforming, and having
 a top surface; 
 a bottom surface; 
 a toe end; 
 a heel end; 
 a curvature formed on the sole from the heel end to the toe end of the sole between the bottom surface and the top surface of the sole and corresponding to a curvature of a bottom surface of a user's foot; and 
 at least one engaging hole formed through the bottom surface and the top surface of the sole adjacent to the toe end of the sole to engage a pedal of a bicycle; and 
 an insole being made of soft materials, abutting against the top surface of the sole, and having 
 a heel end; 
 a toe end; 
 a curvature formed on the insole from the heel end to the toe end of the insole and corresponding to the curvature of the bottom surface of the user's foot; 
 a heel portion; 
 an arch portion formed with the heel portion; 
 a metatarsus portion formed with the arch portion and being opposite to the heel portion; and 
 a toe portion deposited on the toe end of the insole and formed with the metatarsus portion; 
   wherein the insole is deposited in the cycling shoe and abuts the sole, and the user's foot wears the cycling shoe and the weight of the user's foot is applied on the insole and the sole of the cycling sole, since the material of the insole is softer than the material of the sole to enable the insole to deform, and the weight of the user's foot is pressed on the insole, and the insole completely abuts the user's foot and the sole without forming any interspaces between the user's foot and the sole.   
     
     
         2 . The shoe sole structure of a cycling shoe for bicycles as claimed in  claim 1 , wherein the insole has a strengthening portion deposited on a bottom surface of the insole, abutting the top surface of the sole, and having a rigid strength between that of the insole and the sole. 
     
     
         3 . The shoe sole structure of a cycling shoe for bicycles as claimed in  claim 2 , wherein the sole has at least one ventilating hole formed through the bottom surface and the top surface of the sole adjacent to the heel end of the sole to provide a ventilating effect. 
     
     
         4 . The shoe sole structure of a cycling shoe for bicycles as claimed in  claim 3 , wherein
 the sole has two ventilating holes formed through the top surface and the bottom surface of the sole at a spaced interval; and   the sole further has
 a mounting recess being elongated, formed in the top surface of the sole adjacent to the heel end of the sole, communicating with the ventilating holes and having two opposite inner sidewalls; 
 an engaging segment deposited in the mounting recess adjacent to the heel end of the sole; and 
 a switch sheet slidably mounted in the mounting recess, engaging with the engaging segment, and having
 a rear end extending to the engaging segment; 
 a front end; 
 a bottom side; 
 a switching hole formed through the switch sheet between the rear end and the front end of the switch sheet and selectively communicating with one of the ventilating holes; and 
 a shifting block downwardly formed on and protruding from the bottom side of the switch sheet adjacent to the switching hole, and extending out of the bottom surface of the sole via one of the ventilating holes. 
 
   
     
     
         5 . The shoe sole structure of a cycling shoe for bicycles as claimed in  claim 4 , wherein
 the engaging segment of the sole has multiple teeth formed on the opposite inner sidewalls of the mounting recess adjacent to the heel end of the sole;   the switch sheet has
 two elastic arms formed on and protruding from the rear end of the switch sheet at a spaced interval and respectively facing the opposite inner sidewalls of the mounting recess; and 
 a positioning segment formed on the elastic arms and engaging the teeth of the engaging segment. 
   
     
     
         6 . The shoe sole structure of a cycling shoe for bicycles as claimed in  claim 5 , wherein the shoe sole structure further has a middle sole deposited on the sole to cover the mounting recess and the switch sheet, and having
 two communicating holes formed through the middle sole and respectively aligning with the ventilating holes of the sole; and   two filtering nets respectively formed in the communicating holes to prevent crushed stone or sand from moving into the shoe sole structure via the ventilating holes and the switching holes.   
     
     
         7 . The shoe sole structure of a cycling shoe for bicycles as claimed in  claim 6 , wherein the insole is deposited on the middle sole and has multiple air holes formed through the insole at spaced intervals, and part of the air holes communicate with the communicating holes of the middle sole.
