L'invention concerne un châssis de moule qui, dans un exemple, comprend un corps pour former partiellement une semelle intermédiaire d'un article chaussant dans un procédé de moulage par injection. Le châssis de moule à titre d'exemple comprend une découpe le long d'un axe longitudinal du corps, la découpe lui permettant de s'apparier de manière amovible avec un insert personnalisé. Un insert personnalisé à titre d'exemple comprend un corps respectif pour s'apparier de manière amovible avec la découpe du châssis de moule d'une façon telle qu'une surface intérieure du corps de l'insert personnalisé aide au moins en partie à former une semelle intermédiaire de l'article chaussant dans le procédé de moulage par injection. Le corps de l'insert personnalisé a une forme personnalisée ou un motif personnalisé à la surface intérieure pour personnaliser une forme ou un motif d'une surface extérieure de la semelle intermédiaire.
