Abstract

A boot having a first footwear element and a second footwear element, the second footwear element being configured to be removably inserted into the first footwear element, the first element footwear extending lengthwise from a rear end to a front end, widthwise between a lateral side and a medial side, and height-wise from a base to an upper end, the second footwear element extending lengthwise from a rear end to a front end, widthwise between a lateral side and a medial side, and height-wise from a base to an upper end. The boot includes a retaining device to retain the rear end of the second footwear element at the rear end of the first footwear element.

First claim

The invention claimed is:

1. A boot comprising:
a first footwear element and a second footwear element;
the second footwear element being sized, structured, and arranged to be removably inserted into the first footwear element;
the first footwear element extending lengthwise from a rear end to a front end, widthwise between a lateral side and a medial side, and height-wise from a base to an upper end;
the second footwear element extending lengthwise from a rear end to a front end, widthwise between a lateral side and a medial side, and height-wise from a base to an upper end;
a second-footwear-element retainer configured to retain the rear end of the second footwear element against upward movement of the second footwear element at the rear end of the first footwear element, said second-footwear-element retainer comprising:
a first part of the first footwear element, and a second part of the second footwear element;
the first part and second part having complementary shapes;
the first part comprising an internal stop positioned internally of the first footwear element and spaced from an internal boot-supporting surface of the first footwear element, the first part being configured to engage with the second part when the second footwear element is positioned within the first footwear element;

the first footwear element comprising a crampon-retaining external stop positioned externally of and extending rearwardly at the rear end of the first footwear element, and configured to be engaged by a crampon retaining device;
the internal stop of the first part including an arm extending in a direction forwardly from the rear end of the first footwear element, the arm being configured to engage with the second part; and
the external stop of the first footwear element comprising the arm of the internal stop of the first part.

2. The boot according to claim 1 , wherein:
the second part of the retainer is an end piece, projecting rearwardly from the end of the second footwear element.

3. The boot according to claim 1 , further comprising:
a guide structured and arranged to position the second footwear element into the first footwear element.

4. The boot according to claim 3 , wherein:
the guide and the first part of the retaining device are connected to one another.

5. The boot according to claim 3 , wherein:
the inner stop, the outer stop, and the guide form a unitary one-piece element.

6. The boot according to claim 5 , wherein:
the one-piece unitary element is a subdivision of a rear portion of the first footwear element.

7. The boot according to claim 1 , wherein:
the first footwear element has a rear opening for receiving the second footwear element into the first footwear element.

8. A boot according to claim 7 , wherein:
the opening is a wide cutout;
the first footwear element comprises a tongue configured to block the opening, as well as a connecting mechanism structured and arranged for selectively blocking and unblocking the tongue to the remainder of the first footwear element via the opening.

9. The boot according to claim 8 , wherein:
the connecting mechanism comprises two spaced-apart slide fasteners comprising a lateral slide fastener and a medial slide fastener.

10. The boot according to claim 7 , wherein:
the rear opening is a slit.

11. The boot according to claim 10 , wherein:
a slide fastener closes the slit.

12. The boot according to claim 8 , wherein:
the tongue has a rear surface comprising a rear surface portion of the upper portion of the first footwear element;
the cutout has a transverse width between medial and lateral edges that demarcate the cutout; and
the rear surface of the tongue has a width occupying the width of the cutout.

13. The boot according to claim 1 , wherein:
the first footwear element has a front opening.

14. The boot according to claim 1 , wherein:
the upper end of the second footwear element has a circumferential edge, said circumferential edge being lower than the upper end of the first footwear element.

15. The boot according to claim 1 , wherein:
the second footwear element comprises an outer sole assembly and an upper; and
the second part of the retainer is a subdivision of the outer sole assembly of the second footwear element that projects rearward beyond the upper.

16. The boot according to claim 1 , wherein:
the rear end of the second footwear element is a heel of the second footwear element; and
the second part of the retainer is an external rear end piece, projecting rearwardly from the heel of the second footwear element.

17. The boot according to claim 1 , wherein:
the first part of the first footwear element has an L-shape;
the L-shape is comprised of:
an upwardly extending arm; and
the arm of the internal stop of the first part extending forwardly from an upper end of the upwardly extending arm.

18. The boot according to claim 17 , further comprising:
a guide structured and arranged to position the second footwear element into the first footwear element, the guide extending upwardly from the arm of the internal stop of the first part.

19. The boot according to claim 1 , wherein:
the first footwear element comprises a foot-supporting base and a foot-covering upper portion from a lateral side to a medial side.

20. The boot according to claim 1 , wherein:
the first footwear element comprises a foot-supporting base and a foot-covering and ankle-covering upper portion.

21. Art assembly comprising:
a crampon; and
a boot comprising:
a first footwear element and a second footwear element;
the second footwear element being sized, structured, and arranged to be removably inserted into the first footwear element;
the first footwear element extending lengthwise from a rear end to a front end, widthwise between a lateral side and a medial side, and height-wise from a base to an upper end;
