Abstract: According to one aspect, the shoe sole (10) comprises at least one main ground engagement section (22) specifically designed to respond to certain modes of solicitation by the foot of the player. Such section is provided with a sculpted pattern having recesses (102) and solid areas (100). The recesses and solid areas are distributed to minimize pressures or stress differences throughout the ground engagement section concerned so as to provide better adherence and lower wear by abrasion in response to such mode of solicitations. Preferably this arrangement is applied to more than one main ground engagement section (22, 24, 42, 44) in the shoe sole, each of which offers a specific response to a particular mode of solicitation by a player in action. According to a preferred embodiment the recesses are made of elongated cells opening (102) in a corresponding solid area through an elongated aperture (101) with rounded ends (108). The application of these principles to the production of a tennis shoe is described.

Abstract: Tread for a tyre for a two-wheel vehicle improving grip when running on a usage surface liable to become slippery; this tread comprising blocks (1, 2, 3) separated from one another by grooves (4), each block comprising a contact face (10, 20, 30) intended to come into contact with the usage surface as the tyre is running and lateral faces intersecting the contact face to form edge corners delimiting a contour of the contact face having a geometric shape with at least three branches, each branch (11, 21, 31) ending in a point (110, 210, 310) the angle of which is at least equal to 20 degrees and at most equal to 90 degrees, the branches (11, 21, 31) of each block (1, 2, 3), considered two by two, between them determining setback parts (12, 22, 32), each block (1, 2, 3) being provided with slits (111, 112, 113; 211, 212, 213; 311, 312, 313) terminating at one of their ends in one of the setbacks formed on the face of the block and at a same location at their other end so as to create elementary patterns compris

Abstract: The invention concerns a tire (10) comprising a tread (40) provided with a rolling surface, at least one recess (90) being formed in the tread, which recess opens onto the rolling surface, the recess being delimited by a bottom wall (91) and one single side wall (92), the tire also comprising at least one appliqué (100; 1001-1002) comprising at least one portion of a color other than black, and the appliqué being inserted into the recess and fixed by means of an adhesive (110) to at least a portion of said bottom or side wall, in such a way that the portion of a color other than black of the appliqué is visible from a viewpoint outside of the tread and facing the appliqué. The invention also concerns a method and a kit for decorating a tire.
