In a preferred embodiment of the article of footwear shown in the drawings, the article of footwear is a pair of athletic shoes. However, it will be appreciated that the present invention may be applied to other types of lace-up footwear that are desired to be worn without lacing and without altering the appearance of the lace-up shoe.

In FIGS. 1 to 3 , a shoe 1 according to a preferred embodiment of the invention is shown. The shoe has a sole 2 made of elastic material usually used in the sole structure of sports shoes. The sole 2 may be constructed, as is typical, with an outsole, a midsole and an insert. The shoe 1 has a length extending from the rear heel end 3 of the sole to the front toe end 4 , and the shoe 1 has a width between the left side 5 and the right side 6 of the sole 2 . The upper 7 of the shoe is fastened to the sole 2, extending upwardly from the sole 2, as is conventional. The upper 7 is made of flexible material, such as leather or fabric. The upper 7 wraps around the front of the upper surface of the sole of the shoe, from the right side of the heel (referred to as the upper right side 8) around the toe end of the sole (referred to as the vamp 9) to the left side of the heel (referred to as The shoe upper left side 10) extends upwards. Unlike conventional shoes, the upper does not run around the heel end 3 of the sole 2 . The upper 7 has upwardly a left free rear edge 11 and a right free rear edge 12 separated by a gap having a width corresponding to the width of the heel. The rear tongue 13 is bonded to this part of the sole 2 . Said tongue 13 extends upwards with a width such that it extends on one side close to the right free rear edge 12 of the upper 7 and on the other side close to the left free rear edge 11 of the upper 7 . The rear tongue 13 can move independently of the upper 7 and functions like a normal tongue.

Upper left 10 , upper right 8 and rear tongue 13 extend upwardly from sole 2 defining an ankle opening 14 to the interior of the shoe. The ankle opening 14 is also referred to as a collar.

The upper left side 10 extends upwardly from the left side of the sole to the upper left side edge 15 . The upper right side 8 extends upwardly from the sole right side to the upper right side edge 16 . As can be seen in the figures, upper left edge 15 and upper right edge 16 extend forwardly from opposite sides of an upper opening edge 38 towards the front toe end 4 of the sole. The lengths of the upper left edge 15 and the upper right edge 16 define a forefoot opening 17 in the upper 7 of the shoe that opens towards the interior 18 of the shoe.

The upper 7 of the shoe comprises an upper 9 arranged behind the toe end 4 , and a tongue 19 extending rearwardly from the upper 9 . Tongue 16 extends along the length of upper left side 10 and upper right side 8 to a distal end of tongue 19 . The tongue 19 has a width between a left edge 20 and a right edge 21 of the tongue. The length and width of the tongue position the tongue side edges 20 , 21 under the upper left side 10 and the upper right side 8 and extend the tongue over the forefoot opening 17 of the shoe 1 .

A plurality of shoelace holes 22 are provided on the upper left side 10 and the upper right side 8 . These lace holes 22 are occupied by a part of the lace 23 which closes the upper 7 of the shoe at the forefoot opening 17 of the shoe. These lace holes 22 may be, for example, D-rings or quick lace hooks. However, in the preferred embodiment of the present invention, the lace holes 22 are provided by a plurality of eyelets or locking rings on the upper left side 10 and the upper right side 8 . The eyelets provide the desired lace-up look. The eyelet lace holes 22 are arranged linearly along the left edge 10 of the upper and along the right edge 8 of the upper. As seen in the figures, the lace apertures 22 extend substantially the entire length of the upper left edge 10 and the upper right edge 8 between the edge of the upper opening and the toe end of the upper.
