Abstract

Size-adjustable footwear includes an outer shell and a liner disposed within the shell. The liner has an upper, a heel, and a toe. An insert is releasably receivable within the toe of the liner. The liner has a first size which is defined between the heel and the insert when the insert is received within the toe, and a second size which is defined between the heel and the toe when the insert is not received within the toe. The first size is less than the second size. A user may select footwear based on the smaller first size, and then as his or her feet grow, remove the insert to accommodate the larger feet.

Claims

1. Size-adjustable footwear comprising:

a shell having a sole and an upper;

a liner disposed within said shell and including an upper, a heel, and a toe;

said toe having a first side portion and a second side portion; and

an insert receivable within said toe of said liner, said insert having a front portion, a first side portion, and a second side portion, said insert being releasably attachable within said liner and having a width w which is greater than the width of said toe of said liner such that said first and second side portion of said insert wraps within said toe of said liner and partially extends rearward down the first and second side portion of said liner to accommodate for the length of a wearer'"'"'s foot and for the width of the toes of the wearer'"'"'s foot;

said liner having a first size defined between said heel and said insert and between said first side portion of said insert and said second side portion of said insert when said insert is received within said toe and a second size defined between said heel and said toe and between said first side portion of said toe and said second side portion of said toe when said insert is not received within said toe, said first size being less than said second size; and

said front portion of said insert following a natural curve of a wearer'"'"'s frontal toe line, said first side portion of said insert and said second side portion of said insert extending along a side of the wearer'"'"'s foot.

2. Size-adjustable footwear as claimed in claim 1 wherein said insert comprises resilient material.

3. Size-adjustable footwear as claimed in claim 2 wherein said resilient material comprises foam rubber.

4. Size-adjustable footwear as claimed in claim 1 wherein:

said insert comprises a layer of fastening material; and

said liner comprises a layer of complementary fastening material for releasably engaging with said fastening material of said insert.

5. Size-adjustable footwear as claimed in claim 4 wherein said fastening material comprises hook-and-loop fasteners.

6. Size-adjustable footwear as claimed in claim 1 wherein said insert is configured to complement the shape of said toe of said liner.

7. Size-adjustable footwear as claimed in claim 6 wherein said insert includes a substantially arcuate upper side and a substantially flat lower side.

8. Size-adjustable footwear as claimed in claim 1 wherein said upper of said liner includes:

a vamp;

an opening extending rearward from said vamp; and

a tongue attached to said vamp for covering said opening;

said vamp and said opening being configured so that said toe is readily accessible through said opening.

9. Size-adjustable footwear as claimed in claim 1 further comprising an outer protective shell.

10. Size-adjustable footwear as claimed in claim 9 wherein said liner is removably disposed within said shell.

11. Size-adjustable footwear as claimed in claim 9 wherein said shell includes a sole adapted to mount to a locomotive assembly.

12. Size-adjustable footwear as claimed in claim 11 wherein said locomotive assembly comprises an in-line wheel assembly.

13. A method for adjusting the size of footwear, comprising the steps of:

providing footwear including;

a shell having a sole and an upper;

a liner disposed within said shell and having an upper, a heel, and a toe;

said toe having a first side portion and a second side portion; and

an insert releasably received within said toe of said liner, said insert having a front portion, a first side portion, and a second side portion, said insert being releasably attachable within said liner and having a width w which is greater than the width of said toe of said liner such that said first and second side portion of said insert wraps within said toe of said liner and partially extends rearward down the first and second side portion of said liner to accommodate for the length of a wearer'"'"'s foot and for the width of the toes of the wearer'"'"'s foot;

said liner having a first size defined between said heel and said insert and between said first side portion of said insert and said second side portion of said insert when said insert is received within said toe and a second size defined between said heel and said toe and between said first side portion of said toe and said second side portion of said toe when said insert is not received within said toe, said first size being less than said second size;

said front portion of said insert following a natural curve of a wearer'"'"'s frontal toe line, said second side portion of said insert extending along a side of the wearer'"'"'s foot; and

removing said insert from said liner.

14. A method as claimed in claim 13 further comprising the step of positioning said insert within said toe of said liner.

15. A method as claimed in claim 13 further comprising the step of:

providing said liner with a vamp;

extending an opening rearward from said vamp; and

configuring said vamp and said opening so that said toe is readily accessible through said opening.

16. A method as claimed in claim 13 further comprising the step of:

providing a sole adapted to mount to a locomotive assembly.

17. A method as claimed in claim 16 wherein said locomotive assembly comprises an in-line wheel assembly.

18. A method as claimed in claim 13 wherein said insert comprises resilient material.

19. A method as claimed in claim 18 wherein said resilient material comprises foam rubber.

20. A method as claimed in claim 13 wherein:

said insert comprises a layer of fastening material; and

said liner comprises a layer of complementary fastening material for releasably engaging with said fastening material of said insert.

21. A method as claimed in claim 20 wherein said fastening material comprises hook-and-loop fasteners.
