Abstract
Abstract In the inner lining shoe for boots, particularly ski boots, an fore tongue is anchored in a floating manner to the upper, so as to be displaceable in a controlled manner with respect to the upper under the action of elastic return means. Elastically deformable means are also provided to prevent the deformation of the upper under stress, while permitting the bending of the leg portion with respect to the true upper.
