Title (EN) SHOE SOLE CONSTRUCTION
(FR) CONSTRUCTION D'UNE SEMELLE DE CHAUSSURE
Abstract: front page image
(EN)A shoe sole construction which features an outer sole (18) having at least one opening (26) through which a protrusion (30) of a less dense midsole (16) extends. The cutout area (26) of the more dense outsole (18) decreases the overall weight of the sole (12), while the less dense protrusion (30) aids in cushioning the foot to provide greater comfort and support. Other protrusions (32 and 68) may also be provided through others openings in the outsole to further lessen weight and increase the cushioning effect on the foot. Additionally, grooves (42) may be provided on the upper surface (40) of the midsole (16) to increase flexibility of the sole (12) and further aid in cushioning the foot and providing peripheral support where needed. The invention may be applied to athletic shoes (Figures 1-9), a women's high-heeled shoe (Figures 10-14), or other footwear.
(FR)Une construction d'une semelle de chaussure se caracterise par une semelle externe (18) ayant au moins une ouverture (26) au travers de laquelle s'etend une saillie (30) d'une semelle mediane moins dense (16). La zone decoupee (26) de la semelle externe plus dense (18) diminue le poids total de la semelle (12), tandis que la saillie moins dense (30) contribue a l'amortissement du pied lui conferant un meilleur confort et un plus grand support. D'autres saillies (32 et 68) peuvent egalement etre amenagees au travers d'autres ouvertures dans la semelle externe pour diminuer encore plus le poids et augmenter l'effet d'amortissement du pied. De plus, des rainures (42) peuvent etre amenagees sur la surface superieure (40) de la semelle mediane (16) pour augmenter la flexibilite de la semelle (12) et contribuer a l'amortissement du pied en constituant un support peripherique la ou cela est necessaire. L'invention peut etre appliquee a des chaussures de sport (figures 1-9), une chaussure a talon haut pour femme (figures 10-14), ou autre type de chaussure.
