id="p-0053" num="0052">As shown in FIG. 7 to FIG. 11, the upper includes a first upper 1 and a second upper 2. The adjustable structure includes a first connecting strap 42, a first woven strap 43 and the pin buckle 3. The first connecting strap 42 and the first woven strap 43, under cooperation of the sole 5, wrap the first upper 1 and the second upper 2. One end of the first connecting strap 42 is fixed to the left side of the sole 5, and one end of the first woven strap 43 is fixed to the right side of the sole 5. The pin buckle 3 is arranged on the first connecting strap 42. A gap is defined between the second rib 312 and the first connecting strap 42 for the first woven strap 43 to pass through. When the first woven strap 43 is passed through the buckle 31, the pin 32 can pass through a woven perforation 41 of the first woven strap 43 to prevent the first woven strap 43 from being separated from the buckle 31. The pin 32 may be inserted into a different woven perforation 41, so as to adjust a connection position at which the first connecting strap 42 is connected with the first woven strap 43, and thus tighten or loosen the first upper 1 and the second upper 2. The bottom of the first upper 1 is fixed to the left side of the sole 5, and the bottom of the second upper 2 is fixed to the right side of the sole 5. The first upper 1 and the second upper 2 are elastic.

Optionally, the first connecting strap 42 is a woven strap, and it has woven perforations 41.

The above arrangement has advantages as follows. The materials of the first upper 1 and the second upper 2 can be adjusted as required. For example, if the shoe is expected to be more ventilated, the first upper 1 and the second upper 2 may be in a woven structure with the woven perforations 41, so that it is more ventilated. If it is desired to set a pattern(s) on the first upper 1 and the second upper 2 to make the shoe more beautiful, the first upper 1 and the second upper 2 may use cloth or PU and other materials (in some embodiments, an elastic sheet may be optionally provided in the interior) to facilitate spraying of patterns on the first upper 1 and the second upper 2.

Optionally, the first upper 1 and the second upper 2 are partially overlapped to define an arch for the user's foot to pass therethrough.

When the user desires to adjust the width of the upper, it may first release the pin 32 from the woven perforation 41 so that the first connecting strap 42 and the first woven strap 43 can be detached from each other. Next, the first woven strap 43 is passed through the buckle 31 to adjust the degree of tightening or loosening between the first upper 1 and the second upper 2. After the ideal position is reached, the pin 32 can pass through a woven perforation 41 of the first woven strap 43 to fix the relative position of the first connecting strap 42 and the first woven strap 43, thereby locking the degree of closure between the first upper 1 and the second upper 2 to provide a relatively fixed upper.

Optionally, as shown in FIG. 12 and FIG. 13, the shoe may also be provided with an arched upper in front of the first upper 1 and the second upper 2, for the user's foot to pass therethrough.

Third Embodiment

As shown in FIG. 14 and FIG. 15, the first connecting strap 42 and the woven strap 4 serve as a part of the upper. The pin 32 may be inserted into a different woven perforation 41 to adjust a connecting position at which the first connecting strap 42 is connected with the woven strap 4, and thus adjust the total length of the first connecting strap 42 and the woven strap 4. The adjustable structure includes the first connecting strap, the first woven strap 43 and the pin buckle 3. The first connecting strap 42 and the first woven strap 43 serve as a part of the upper. One end of the first connecting strap 42 is fixed to one of the left side and the right side of the sole 5, and one end of the first woven strap 43 is fixed to the other of the left side the right side of the sole 5. The pin buckle 3 is arranged on the first connecting strap 42. The first connecting strap 42 and the woven strap 4 are connected at a middle area of the sole.
