Abstract

An item of footwear, particularly a motorcycle boot (1), includes a rigid shell (4) which defines a body that is designed to surround the foot of the user. The body consists of a lower sole-forming part (20), an upper vamp-forming part (22), an inner lateral part and an outer lateral part, the lateral parts connecting the aforementioned lower and upper parts. The inventive item of footwear includes an opening (16, 18) in one of the four constituent body parts, which passes through the rigid shell and which is sealed by a flexible half-sole (12, 14).

Claims

1. Item of footwear, comprising:

a rigid shell which is produced from a first material and which defines a body which is intended to surround the foot of a user, the body having a lower portion which forms a sole, an upper portion which forms a vamp, an inner lateral portion and an outer lateral portion, said lateral portions connecting the lower portion and the upper portion, these four portions extending in an extension direction between a first zone which forms a heel and a second zone which forms a tip; and

an opening defined in only one of said four portions of the body, said opening extending through the rigid shell and being closed by means of a flexible pad which is produced from a second material, said second material being more flexible than the first material.

2. Item of footwear according to claim 1, wherein the opening is provided with spacing from the ends of the body in the extension direction.

3. Item of footwear according to claim 1, wherein the opening is provided in a zone of the lower portion which serves to support the sole of the foot of the user.

4. Item of footwear according to claim 3, wherein the opening extends transversely to the direction of extension over less than half the width of the item of footwear.

5. Item of footwear according to claim 3, wherein the pad extends in a recessed manner relative to the rigid shell.

6. Item of footwear according to claim 2, wherein the opening is provided in the upper portion.

7. Item of footwear according to claim 6, wherein the opening is provided substantially at the centre of the upper portion relative to the extension direction.

8. Item of footwear according to claim 1, wherein the first material has a hardness which is at least 20% greater than the hardness of the second material.

9. Item of footwear according to claim 8, wherein the pad has a hardness of between 60 and 80 Shore.

10. Item of footwear according to claim 1, further comprising another rigid shell which defines an upper which is intended for receiving the leg of the user and means for articulating the upper relative to the body.

11. Item of footwear according to claim 2, wherein the opening is provided in a zone of the lower portion which serves to support the sole of the foot of the user.

12. Item of footwear according to claim 4, wherein the pad extends in a recessed manner relative to the rigid shell.

13. Item of footwear according to claim 3, further comprising another opening provided in the upper portion.

14. Item of footwear according to claim 4, further comprising another opening provided in the upper portion.

15. Item of footwear according to claim 5, further comprising another opening provided in the upper portion.

16. Item of footwear according to claim 2, wherein the first material has a hardness which is at least 20% greater than the hardness of the second material.

17. Item of footwear according to claim 3, wherein the first material has a hardness which is at least 20% greater than the hardness of the second material.

18. Item of footwear according to claim 4, wherein the fist material has a hardness which is at least 20% greater than the hardness of the second material.

19. Item of footwear according to claim 5, wherein the first material has a hardness which is at least 20% greater than the hardness of the second material.

20. Item of footwear according to claim 6, wherein the first material has a hardness which is at least 20% greater than the hardness of the second material.
