For use in a sole, insole, or heel portion of a footwear article, a footpad (10) is described, having an upper surface on which are disposed a plurality of resilient lugs (30). The top surfaces (32) of the lugs (30) define a foot supporting surface wherein mutually parallel, spaced-apart edges of the adjacent lugs define a complementary arrangement of top surfaces. The side surfaces (34) of adjacent lugs (30) expand into the void, and retreat therefrom, cyclically expelling and ingesting air beneath the foot. With heavy compression, the top surfaces (32) of adjacent lugs (30) are approximated to one another to provide a substantially continuous and substantially uniformly supportive foot-supporting surface. Structures selectively providing for preferred combination of ventilation, cushioning, and stable and comfortable support for bearing heavy loads are described. The selective provision of enhanced support for heavy load bearing parts of the foot is described.
La présente invention concerne une semelle (10) s'utilisant dans la partie semelle, semelle intérieure ou talon d'une chaussure, comportant une surface supérieure pourvue d'une pluralité de reliefs élastiques (30). Les surfaces supérieures (32) des reliefs (30) forment une surface de soutien du pied, les bords parallèles et espacés des reliefs adjacents formant une structure complémentaire des surfaces supérieures. Les surfaces latérales (34) des reliefs adjacents (30) s'étendent et se rétractent du vide, chassant et aspirant ainsi de manière cyclique l'air sous le pied. Sous l'effet d'une forte compression, les surfaces supérieures (32) des reliefs adjacents (30) s'approchent l'une de l'autre pour former une surface de support de pied sensiblement continue et uniforme. En outre, cette invention concerne des structures offrant de manière sélective des combinaisons préférées d'aération, d'amortissement, et de support stable et confortable pour soutenir des charges lourdes. Enfin, cette invention fournit un support amélioré pour les parties de pieds supportant une charge lourde.
