CA 2198787

A heat mouldable boot liner has an upper portion extending upwardly from a foot portion and having a front gap extending upwardly through the upper portion. The foot portion has pair of flaps extending along the foot portion and defining a further gap extending into the front gap, the flaps being adjustable to bring one of the flaps into overlapping relationship relative to the other of the flaps so as to thereby close the further gap. A tongue extends upwardly from the other one of the flaps within the upper portion of said liner for forming a closure behind the front gap. The foot portion includes a heel portion shaped to fit snugly the user's heel. The present liner can be heat-moulded in a single-stage moulding operation.

L'invention porte sur une doublure de botte moulée à chaud comprenant une partie supérieure, se prolongeant vers le haut à partir d'une partie pied, et une ouverture avant se prolongeant vers le haut à travers la partie supérieure. Deux rabats se prolongent le long de la partie pied et définissent une seconde ouverture rejoignant l'ouverture avant. Ils s'ajustent de façon qu'un des rabats chevauche l'autre et ferme ainsi la seconde ouverture. Une languette se prolonge, à partir de l'autre rabat, vers le haut et à l'intérieur de la partie supérieure de la doublure afin de former un élément de fermeture derrière l'ouverture avant. La partie pied inclut une partie talon formée pour s'ajuster avec précision au talon de l'utilisateur. La doublure en question peut être moulée à chaud au cours d'une opération de moulage en un temps.
