    •  DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
  • With reference to FIGS. 1 to 3, a first embodiment of a shoe sole in accordance with the present invention comprises a main body 10 and a strip 20.
  • The main body 10 is flexible and elongated and has a bottom surface 15, a front end 11, a rear end 12, a through hole 13 and a slot 14. The rear end 12 of the main body 10 is opposite to the front end 11 of the main body 10. The through hole 13 is elongated and is formed through the main body 10. Preferably, the through hole 13 extends toward the front end 11 and the rear end 12 of the main body 10.
  • With reference to FIGS. 5 and 6, the slot 14 is formed in the main body 10 and communicates with a front side of the through hole 13. The slot 14 has a cross section, a central section and a groove 141. The groove 141 is located at the central section of the slot 14 and is formed through the bottom surface 15 of the main body 10.
  • With reference to FIGS. 2, 3 and 6, the strip 20 is hard, is mounted in the through hole 13 and is detachably connected with the main body 10. The strip 20 has flexibility higher than that of the main body 10.
  • Preferably, the strip 20 is elongated and extends toward the front end 11 and the rear end 12 of the main body 10. The strip 20 has a front end, a rear end, a cross section, two opposite side surfaces, a bottom surface and a rib 21. The front end of the strip 20 is inserted into the slot 14. The rear end of the strip 20 is opposite to the front end of the strip 20 and is connected with the main body 10 by a screw.
  • The cross section of the strip 20 is T-shaped. The rib 21 protrudes from the bottom surface of the strip 20 and has a front end inserted into the groove 141.
  • A width of the strip 20 is smaller than that of the through hole 13. Two gaps G are formed between the strip 20 and the main body 10. Each gap G is located between a side surface of the strip 20 and an inner wall 131 of the through hole 13.
  • With reference to FIGS. 7 and 8, a second embodiment of the shoe sole in accordance with the present invention is substantially the same as the first embodiment.
  • The through hole 13A has a longitudinal section, a width and a length. The longitudinal section of the through hole 13A is rectangular.
  • The strip 20A has a longitudinal section, a width, a length, a front end and a rear end. The longitudinal section of the strip 20A is rectangular.
  • The width of the strip 20A is the same as that of the through hole 13A. The length of the strip 20A is longer than that of through hole 13A.
  • The front end of the strip 20A is connected with the main body 10A by a screw. The rear end of the strip 20A is opposite to the front end of the strip 20A and is connected with the main body 10A by a screw.
  • With reference to FIGS. 9 and 10, a third embodiment of the shoe sole in accordance with the present invention is substantially the same as the first embodiment.
  • The through hole 13 extends toward the front end 11 and the rear end 12 of the main body 10B.
  • The number of the at least one strip 20B is multiple, and the strips 20B are located in the through hole 13 at intervals. Each strip 20B extends toward two opposite inner walls 131B of the through hole 13 and has two opposite ends respectively connected with the main body 10B by screws.
  • Alternatively, the through hole 13 and the strip 20 may extend along the width of the main body 10 toward two flanks of the main body 10. The present invention does not limit the format, number, and shape of longitudinal section of the through holes 13,13A and the strip 20,20A,20B. Two opposite ends of the strip 20 may be both inserted into the main body 10 or be connected with the main body 10 by screws. The present invention does not limit the means of connection between the main body 10 and the strip 20.
  • From the above description, it is noted that the present invention has the following advantages:
  • 1. Adjustable Flexibility of the Sole:
  • With the elongated through hole 13,13A, the sole becomes flexible and a user feels comfortable with the sole. Moreover, the at least one strip 20,20A,20B is mounted in the through hole 13,13A and is detachably connected with the main body 10,10A,10B. By replacing the strips 20,20A,20B having different flexibilities, the flexibility of the sole is adjustable to meet different needs of a user or different situations. Alternatively, the user may also mount no strip to the sole.
  • 2. Cost Reduction:
  • The user only needs to purchase multiple strips 20,20A,20B having different flexibilities, and as the strip 20,20A, 20B is replaceable and small in volume, this can save purchasing costs and storage space.
  • 3. Enhanced Structural Strength:
  • With the rib 21 protruding from the bottom surface of the strip 20, 20A, 20B, the strip 20,20A,20B has good structural strength.
  • 4. Easy Replacement:
  • Because the groove 141 of the first embodiment is formed through the bottom surface 15 of the main body 10, the strip 20 is easily inserted into the slot 14 from the bottom surface 15 of the main body 10. Accordingly, the replacement of the strip 20 of the first embodiment is easy.
  • 5. Good Ventilation:
  • The first and third embodiments of the soles have gaps G Accordingly, the soles have good ventilation and smell in the shoes can quickly escape.
  • Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
