first embodiment

[0035]The first embodiment, which is described with reference to FIGS. 1 to 6, relates more specifically to shoes for walking or running on flat or uneven terrain. However, the invention is applicable to other fields, such as those mentioned above.

[0036]As shown in all FIGS. 1 to 6, a walking or running shoe 1 is adapted to receive the foot of a user.

[0037]Conventionally, the shoe 1 includes an outer sole assembly 2 and a flexible upper 3. The shoe 1 extends lengthwise from a rear end 4, or heel, to a front end 5, or tip, and widthwise between a lateral side 6 and a medial side 7. Therefore, the outer sole assembly 2 extends lengthwise from the heel 4 to the tip 5, and widthwise between the lateral side 6 and the medial side 7. The sole assembly 2 also extends heightwise, or depthwise, between a contact surface 8 and a connecting surface 9. The contact surface 8 is adapted to contact the ground. The connecting surface 9 is used to affix the sole assembly 2 to the remainder of the sh...

second embodiment

[0063]For the second embodiment, according to FIG. 7, the outer sole assembly 2 further includes a first portion 26 and a second portion 27 within the scope of the invention. A lip 57 extends the outer sole assembly 2 in a direction away from the contact surface 8, in the area of the medial side 7, opposite the counter 36. The lip 57 supports the upper 3 transversely.

[0064]What is specific to the second embodiment is that the lip 57 extends the second portion 27 in a direction away from the contact surface 8, in the area of the medial side 7, opposite the counter 36. More precisely, the lip 57 and the second portion 27 form a unitary element. Compared to the first embodiment, this is an alternative construction, which provides the outer sole assembly 2 with increased rigidity on the medial side 7. Therefore, the transverse retention of the counter 36 is firmer. The second portion 27 extends widthwise along a distance between 20% and 70% of the width of the outer sole assembly 2, fro...

third embodiment

[0065]For the third embodiment, according to FIG. 8, the outer sole assembly 2 also includes a first portion 26 and second portion 27 in the spirit of the invention. A lip 67 extends the outer sole assembly 2 in a direction away from the contact surface 8, in the area of the medial side 7, opposite the counter 36. The lip 67 supports the upper 3 transversely.

[0066]What is specific to the third embodiment is that not only the lip 67 extends the second portion 27 in a direction away from the contact surface 8, in the area of the medial side 7, opposite the counter 36, but the second portion 27 also extends along the entire width of the outer sole assembly 2. More generally speaking, the second portion 27 extends widthwise along a distance between 20% and 100% of the width of the outer sole assembly 2, from the medial side 7. Moreover, the second portion 27 has a thickness e which decreases in the transverse direction, from the medial side 7 to the lateral side 6.

Abstract

An article of footwear including an outer sole assembly and a flexible upper, the outer bottom assembly extending lengthwise from a rear end to a front end, width-wise between a lateral side and a medial side, and height-wise between a surface of contact with the ground and a surface for connecting to the remainder of the shoe, the outer sole assembly having, from the rear end to the front end, a rear zone, a central zone, a metatarsal zone, and a front zone, the article of footwear including a counter which reinforces the upper at least above the rear zone. The counter includes a lateral flange and a medial flange, the medial flange being lengthier than the lateral flange.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is based upon French patent application Ser. No. 11 / 02915, filed Sep. 26, 2011, the disclosure of which is hereby incorporated by reference thereto in its entirety, and the priority of which is claimed under 35 USC ยง119.BACKGROUND[0002]1.
