Description:
BACKGROUND OF THE INVENTION 
     The present patent application relates to a shoe using a moulded bottom provided with a series of slots or openings for the application of a closed upper, made up of a fabric or leather strap that embraces the back and the neck of the foot. 
     The bottom belongs to the type of moulded bottoms defined as &#34;box&#34; bottom in the footwear industry, which feature a perimeter edge, inside which the upper is sewn and/or glued. 
     SUMMARY OF THE INVENTION 
     The shoe according to the present invention originates with the intention of creating a shoe in which the upper, although closed, can be fixed to the bottom without sewing and/or gluing it, since these operations require skilled labour and specific equipment or machinery. 
     In this perspective a new &#34;box&#34; bottom has been designed with a special configuration, provided with a series of slots or openings on the edge, used to insert one or more straps to embrace or completely cover both the back and the neck of the foot. 
     In order to guarantee the effective protection of the toes, the bottom incorporates a hollow point, which houses the five toes of the foot, while the back of the bottom incorporates a quite high heel support with slots or opening, in which the strap used to embrace the back of the foot is inserted. 
     From this general description it can be understood how the shoe according to the present invention can be produced without skilled labour or special equipment or machinery, since the only assembling operation is represented by the introduction of the straps into the slots or openings located in the &#34;box&#34; bottom. 
     This operation is so simple that it can be even carried out by the purchaser, thus allowing to market the shoe according to the present invention in a kit, with two components: the bottom and the upper, made up of one or more straps. 
     Finally, it must be noted that the straps are provided with ordinary clips or hook and loop fastener inserts for firm fixing, once the straps have been inserted into the slots or openings and twisted around the foot. 
     According to the specific requirements, the upper can be made up of several straps, one for each opposite pair of slots, or of one long strap twisted in the opposite series of slots or openings. 
     In a preferred embodiment of the invention, the opposite series of slots is located on the two edges of the &#34;box&#34; bottom and on the lateral borders of the heel support. 
     According to an alternative version of the invention, the heel support and the bottom sole feature a transverse series of through openings that end on the two edges of the bottom, in which the straps used to embrace and cover the foot are inserted.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     With reference to FIGS. 1 and 2, the shoe according to the present invention, in a preferred embodiment, consists of a moulded &#34;box&#34; bottom (1), which features a hollow point (2) and a heel support (3) used to embrace and support the heel up to the height of the malleolus approximately. 
     Two opposite series of slots (6) are located on the lateral edges (4) of the bottom (1) and on the borders (5) of the heel support (3), characterised in that the back ending section of each slot is located above the initial section of the adjacent slot, going from the point to the heel. 
     Moreover, the shoe according to the present invention includes an upper made up of one or more straps (7), wide enough to be inserted into the slots (6). 
     As shown in FIG. 1, also the straps (7), just like the slots (6), are partially overlapped in cascade, so that there no empty spaces can exist between two straps, to avoid leaving the foot uncovered. 
     On the other hand, the first slot (6), that is the one located next to the point of the bottom (1), begins beyond the opening (2a) of the hollow point (2), so that the opening remains hidden and protected under the first strap (7). 
     Each strap (7) is provided with ordinary clips or hook and loop fastener inserts (not shown in the figure) used to close it. 
     As already mentioned in the introduction, instead of using a series of straps (7) for each opposite pair of slots (6), a long strap can be inserted consecutively in all the slots (6) according to a twisting direction. 
     With reference to FIGS. 3 and 4, it must be noted that in another constructive version of the shoe according to the invention, the sole (1a) of the bottom (1) and the body of the heel support (3) feature a transverse series of through openings (8) in which the straps (7) are inserted, thus crossing the whole sole (1a) of the bottom (1), coming out from the sides and being folded upwards and above the foot. 
     Also in this constructive version the series of through openings (8) are partially overlapped in cascade. 
     FIGS. 5 and 6 illustrate another constructive version of the shoe according to the invention, in which the bottom (1) and the body of the heel support (3) feature a transverse series of through openings (8) in which the straps (7) are inserted, thus crossing the whole sole (1a) of the bottom (1), coming out from the sides and being folded upwards and above the foot. 
     This version only differs from the one shown in FIGS. 3 and 4 for the fact that the series of through openings (8) are not partially overlapped in cascade, but aligned and regularly spaced. 
     In order to completely cover the foot, in this constructive version the straps (7a) feature sections with different width, more narrow in the section which is inserted into the openings and wider in the section which embraces the foot.
