Title: Shoe structure

Description:
BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      This invention relates to a shoe structure, and more particularly to a comfortable shoe structure.  
      2. Description of the Prior Arts  
      To make the people walk more comfortable, the inner sole of a shoe is usually additionally provided with a shoe pad that is soft and used to bear and relieve the pressure from the foot. Since the shoe pad is flat and foot-like member, and the sole of the foot is not flat (a space between the toe and the sole of the foot, and the arch of the foot), the shoe pad is unable to closely abut against the sole of the foot, so it is difficult to make walk comfortable.  
      As shown in  FIG. 1 , an improved shoe pad  11  is provided with plural protrusions  12  so as to correspond to the space between the toe and the sole of the foot and the arch of the foot. The shoe pad  11  is set on the inner sole of a shoe, so as to make the shoe pad  11  abut closely against the sole of the foot and to make the walk comfortable. However, this shoe pad still has some disadvantages that need to be improved as follows:  
      The shoe pad  11  is unable to integrally combined with the shoe  13  since it is replaceably set on the inner sole, so the shoe pad  11  is moveable relative to the shoe  13 . When the wearer is walking, the shoe pad  11  will move in the walking direction (the front portion of the shoe  13 ), such that the shoe pad  11  will be deformed and even folded, thus the protrusions  12  on the shoe pad  11  are unable to be aligned to the concave portion of the foot. Thereby, it will not only make the walk uncomfortable, but also will probably hurt the foot.  
      The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional shoe structure.  
     SUMMARY OF THE INVENTION  
      The primary object of the present invention is to provide a comfortable shoe structure capable of preventing relative displacement between the shoe pad and the shoe, so as to make the walk comfortable.  
      The shoe structure in accordance with one aspect of the present invention includes:  
      a sole assembly comprising a big sole and a mid sole integrally formed with the big sole;  
      at least a comfortable block fixed between the big shoe and the mid shoe and partially protruded out of the mid shoe;  
      a vamp, a lower edge of which located between the big sole and the mid shoe.  
      The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
      Referring to  FIGS. 3-6 , a shoe structure in accordance with the present invention is shown and generally comprises: a sole assembly  20 , two comfortable blocks  30  and a vamp  40 .  
      The sole assembly  20  includes a roughly foot-shaped big sole  21  and a mid sole  22  which is integrally formed with the big sole  21 . A through hole  221  is formed on the front end of the mid sole  22 , and adjacent to the through hole  221  is formed a gap  222 .  
      The two comfortable blocks  30  includes a resilient member  32  covered with a cloth  31 . Each comfortable block  30  is circumferentially formed with extension  33 . The comfortable blocks  30  are formed between the big sole  21  and the mid sole  22  and located corresponding to the arch of the foot. The extension  33  of the comfortable block  30  is located at the periphery of the through hole  221  and the periphery of the gap  222  of the mid sole  22 . Furthermore, each of the comfortable blocks  30  partially protrudes out of the through hole  221  and the gap  222  of the mid sole  22 .  
      The vamp  40 , a lower peripheral edge of which is a clamping portion  41  that is located between the big sole  21  and the mid sole  22 . The comfortable block  30  protruding out of the gap  222  of the mid sole  22  is partially adhered to the inner side of the vamp  40 . Furthermore, a strengthening portion  42  is formed on the clamping portion  41  and corresponds to the gap  222  of the mid sole  22 , so as to enforce the combining force between the vamp  40  and the mid sole  22 .  
      Referring to  FIG. 5 , since the comfortable blocks  30  is fixed on the sole  20  in a manner that corresponds to the arch of the foot  50  (between the big sole  21  and the mid sole  22 ), the comfortable blocks  30  are integrally formed with the sole  20  assembly. And due to partially protruding out the mid sole  22 , the comfortable blocks  30  are able to abut closely against the arch of the foot for creating a better feeling when walking. Furthermore, the comfortable blocks  30  are fixed on the sole assembly  20  and not integrally combined with the shoe pad, thereby, when the user is walking, slide and displacement of the shoe pad will not cause the displacement of the comfortable blocks  30 . Thus, the present invention makes the walk comfortable. Besides, since the partially protrusive comfortable blocks  30  correspond to the arch of the foot, the sole of the foot is allowed to closely combined with the inner sole of the shoe, which makes the walk comfortable when wearing the shoe of the present invention.  
      It will be noted that, as shown in  FIG. 3 , the processes for making the shoe are explained as follows: choose a shoe last (not show), on which is predetermined with two grooves, put the mid sole  22  on the shoe last in a manner that the through hole  221  or the gap  222  is aligned to the grooves of the shoe last. And then put the comfortable blocks  30  on the mid sole  22  and making the extension  33  abut against the peripheral edge of the through hole  221  and the gap  222 , so that part of the comfortable blocks  30  will insert in the grooves of the shoe last after passing through the through hole  221  and the gap  222 . After that, cover the shoe last with the vamp  40  in a manner that the extension  41  abuts against the periphery of the mid sole  22 . At this moment, the comfortable blocks  30 , the mid sole  22  and the vamp  40  can be integrally assembled to each other through sewing or adhering process, and then to be assembled with the big sole  21 . Finally, a comfortable shoe is obtained by taking out the shoe last.  
      While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
