at least one projection extending from a peripheral edge of the second portion and configured to be engaged with at least one portion of the sole assembly;
at least one aperture formed in the second portion; and
at least one securing device which projects through the at least one aperture to secure the second portion to the sole assembly, wherein the second removable portion is continuously provided from a first lateral side of the sole assembly along a toe portion of the shoe and to a second lateral side of the sole assembly opposite the first lateral side.
2. The shoe according to claim 1 , wherein the second portion includes a substantially planar portion and an upwardly extending side portion formed on at least a part of a peripheral area of the planar portion.
3. The shoe according to claim 2 , wherein the shoe is a tennis shoe.
4. The shoe according to claim 2 , wherein the side portion extends around at least part of a periphery of the shoe.
5. The shoe according to claim 2 , wherein the at least one aperture is formed in the substantially planar portion.
6. The shoe according to claim 5 , wherein the at least one projection includes a protruding portion that extends substantially transversely to a main body of the projection and engages with at least one aperture formed in the shoe.
7. The shoe according to claim 2 , wherein the at least one projection extends from the upwardly extending side portion.
8. The shoe according to claim 1 , wherein the first fixed portion and second removable portion form a tread layer of the shoe.
9. The shoe according to claim 8 , wherein a majority of the tread layer is formed from the first fixed portion.
10. The shoe according to claim 1 , further comprising threaded bores formed in a portion of the shoe, wherein each of the at least one securing device includes a tread area end and a threaded end, the threaded end configured to engage the threaded bores of the shoe.
11. The shoe according to claim 10 , wherein the tread area end is made of a similar material as at least one of the first fixed portion and second removable portion.
12. The shoe according to claim 10 , further comprising:
a coupling tool including at least one prong formed at one end of the coupling tool, configured to engage an at least one prong receiving portion formed in each securing device, to rotate the securing device and couple the threaded end of the securing device to the threaded bores of the shoe.
13. The shoe according to claim 12 , wherein the at least one prong receiving portion extends along a length of the tread area end and a flange portion of the securing device.
14. The shoe according to claim 12 , wherein the at least one prong receiving portion is located at a peripheral edge of the tread area end.
15. The shoe according to claim 1 , wherein the second removable portion is a toe portion.
16. The shoe according to claim 1 , wherein the second portion is sized to extend from the first fixed portion to a toe end of the shoe.
17. A method of replacing a portion of a shoe, comprising:
fixedly securing a first fixed portion to a sole assembly of the shoe;
aligning at least one projection formed on a removable second portion of the sole assembly with a projection receiving portion, wherein the at least one projection extends from a peripheral edge of the removable second portion;
engaging the at least one projection with the receiving portion;
inserting at least a part of at least one securing device through a respective at least one aperture formed in the second portion, to secure the second portion to the sole assembly,
wherein the second removable portion is continuously provided from a first lateral side of the sole assembly along a toe portion of the shoe and to a second lateral side of the sole assembly opposite the first lateral side.
18. The method according to claim 17 , wherein the second portion includes a substantially planar portion and an upwardly extending side portion formed on at least a part of a peripheral area of the planar portion.
19. The method according to claim 18 , wherein the side portion extends around at least part of a periphery of the shoe.
20. The method according to claim 18 , wherein the at least one aperture is formed in the substantially planar portion.
21. The method according to claim 18 , wherein the at least one projection extends out from the upwardly extending side portion.
22. The method according to claim 17 , wherein the first fixed portion and second removable portion form a tread layer of the shoe.
23. The method according to claim 22 , wherein a majority of the tread layer is formed from the first fixed layer.
24. The method according to claim 17 , wherein each of the at least one securing device includes a tread area end and a threaded end, the threaded end configured to engage threaded bores of the shoe.
25. The method according to claim 24 , further comprising:
rotating the securing device with a coupling tool, wherein the coupling tool includes at least one prong formed at one end configured to engage at least one prong receiving portion formed in each securing device, to couple the threaded end of the securing device to the threaded bores.
26. The method according to claim 17 , wherein the at least one projection includes a protruding portion configured to extend substantially transversely to a main body of the projection and engage with an aperture formed in the shoe.
27. The method according to claim 25 , wherein the at least one prong receiving portion is located at a peripheral edge of the tread area end and a flange portion of the securing device.
28. The method according to claim 17 , wherein the second removable portion is a toe portion.
29. The method according to claim 28 , wherein the shoe is a tennis shoe.
30. The method according to claim 18 , wherein the at least one projection extends out from the substantially planar portion.
