Pair of shoes

Abstract

At least one of the pair of shoes has a back portion of the shoe, cut from the collar of the back portion (the top of a shoe above the shoe-heel [the heel of the shoe]), and runs down the back of the shoe. The cut forms a slit running down the back portion of the shoe, forming a right-back portion and a left-back portion of the shoe. The right-side edge of the right-back portion and the left-side edge of the left-back portion are separable from the foot being inserted into the shoe. The right-side edge and the left-side edge return back to their positions when the foot is taken off or when the foot is fully inserted, not overlapping each other when the slit is not separated.

DETAILED DESCRIPTION EMBODIMENTS OF THE INVENTION

(8) A pair of shoes 10 (FIGS. 3 and 4) is described in detail as shown in Figs. FIG. 3 shows a left shoe 15, and FIG. 4 shows a right shoe 20.

(9) FIG. 1 shows a shoe 25 (either of 15 or 20), showing a back portion 30 of the shoe 25, cut from the collar 35 of the back portion 30 (the top of the shoe 40 above the shoe-heel 45 (the heel of the shoe). A cut 50 runs down along the back portion 30 of the shoe. The cut 50 forms a slit 55 running down the back of portion 30 of the shoe 25. One side of the cut 50 is a right-back portion 60, and the other side of the cut 50 is a left-back portion 65 of the shoe 25. The right-back portion 60 has a right-side edge 70, and the left-back portion 65 has a left-side edge 75, as shown in FIG. 4.

(10) As shown in FIGS. 2 and 4, the right-side edge 70 and the left-side edge 75 are separable from the foot 80 is inserted into the shoe 25, and the right-side edge 70 and the left-side edge 75 return back to their positions when foot 80 is either taken out or when the foot 80 is fully inserted into the shoe 25. As one can see from Figs., the right-side edge 70 and the left-side edge 75 are not overlapping each other when the slit 55 is not separated; the right-side edge 70 and the left-side edge 75 meet at the same thickness (not offset) to align and to form a smooth rear surface (that is, the back portion 30) of the shoe 25. Although it is preferable that the right-side edge 60 and the left-side edge 70 do not overlap, it is within the breadth of the claims described herein to have a portion of the right-side edge 60 and the left-side edge 70 overlap, or parts of the right-side edge 60 and the left-side edge 70 stitched together. Also, it is preferable to have both shoes of the pair have the same design for the back portions 30; that is, each shoe has a cut 50 on the back portion 30, but not required.

(11) A variation of the shoes 25 described herein has the right-side edge 70 of the right-back portion 60 and the left-side edge 75 of the left-back portion 65 form an opening 85, so the slit 55 starts from the opening 85. The opening 85 allows the slit 55 on the back portion 30 of the shoe 25 to easily spread and open up to receive the foot 80. Moreover, the opening 85 prevents the slit 55 from ripping beyond the opening 85. Furthermore, the opening 85 may give loose space behind the back-heel 130 for comfort.

(12) The slit 55 may be divided into two parts: an upper part 90 of the slit 55 above the opening 85 and a lower part 95 of the slit 55 below the opening 85. When the back portion 30 of the shoe 25 has both the upper part 90 of the slit 55 and the lower part 95 of the slit 55, it is preferable to have the upper part 90 of the slit 55 longer in length than the lower part 95 of the slit 55. The entry of the foot 80 can easily force the slit 55 to separate wide for easily accepting and accommodating the foot 80 into the shoe 25.

(13) FIG. 3 shows the back portion 30 of the shoe 25. As shown, the slit 55 is designed to run up to a collar 35 and to the very top 40 of the shoe 25 so that the right-side edge 70 of the right-back portion 60 is separable from the left-side edge 75 of the left-back portion 65 at the collar 35, separating the top 40 of the shoe 25 and the collar 35 of the shoe 25.

(14) Another variation of the pair of shoes 10 presented herein has the right-back portion 60 extending upwards to form a right lip 100 and the left-back portion 65 extending upwards to form a left lip 105. The right lip 100 and the left lip 105 form an elongated-collar region 110 above and away from a shoe-heel 45. The elongated-collar region 110 may be used as a handle to hold to assist the foot 80 inserted into the shoe 25. Also, the lips 100, 105 allow the slit 55 to open more easily and widely for the foot 80 to easily push into the shoe 25. In this variation, as well as in other variations, the slit 55 does not have to reach or run through the collar 35 so the elongated-collar region 110 does not separate at the collar 25 at the top 40 of the shoe 25, keeping the collar 25 as one piece, not separated. FIG. 4 shows (also in FIG. 2) the foot 80 is being inserted into the shoe 25. As the foot 80 (the back-heel 130) is pushed onto the back portion 30, especially when the shoe 25 is equipped with the elongated-collar region 110, the back-heel 130 of the foot 80 pushes down on the inside 125 of the back portion 30, forcing the slit 55 to open easily along with the slit 55.

(15) The stretchable material 120 is attached to the inside 125 of the back portion 30 (shown in FIG. 5), overlapping parts of both the right-back portion 60 and the left-back portion 65 inside the shoe 25. The stretchable material 120 provides elasticity to separate the slit 55 apart when the back-heel 130 of the foot 80 is pushed into the shoe 25 and to pull the slit 55 back together after the foot 80 is inserted into the shoe 25 or when the foot 80 is removed from the shoe 25. It is preferable that the stretchable material 120 is not stitched completely (otherwise, completely affixed) on the upper part 135 of the stretchable material 120 so the slit 55 may freely open up and close together due to the elasticity of the stretchable material 120. The stretchable material 120 may be, including but not limited to, spandex, rubber, ribbed fabric, stretchable fabric, and the like. The stretchable material 120 is elastic and should maintain its shape over extended use.

(16) FIG. 6 shows a version of the shoes 10 without the stretchable material 120. The leather or the material used for the shoe 25 may have sufficient elasticity to separate and bring back the back portion 30 of the shoe 25.

(17) While the description, drawings, and references have presented, shown, and described with reference to different embodiments thereof, it will be appreciated by those skilled in the art that variations in form, detail, compositions, and operation may be made without departing from the spirit and scope of the disclosure.
