Abstract

La présente invention concerne une semelle composite et un ensemble fond, qui comprennent deux couches de mousse EVA, la première couche étant une semelle de rembourrage plus douce avec une surface supérieure exposée. La seconde couche est conçue sous forme de soutien de voûte plantaire et se compose de mousse EVA d'une densité/dureté supérieure. Le soutien de voûte plantaire en mousse EVA est attaché à une surface de fond de la semelle de rembourrage en mousse EVA plus douce. Tous deux sont ensuite attachés à une surface supérieure, formée sur un fond de chaussure solide. L'une quelconque des retenues parmi une diversité décorative de retenues supérieures peut être attachée au fond, ce qui assure des chaussures de loisirs et habillées confortables.
