Abstract: A sole is provided in a single-moulding made of non-rigid but elastic material having one or more vertical elements folded over each other in such a manner that the horizontal extension thereof mechanically adapts the width of the sole to the different width of the assembly lasts of the upper of a shoe. This also allows adapting the width of the sole to the variation of the conformation of the feet generated by the daily swellings thereof leaving the normal flexibility and comfort of the shoe unaltered. The user may stabilize the width of the sole to the possible deformation of the foot by injecting, from outside into the widened internal cavity, a foamed two-component fluid material which, upon solidification within a few minutes, blocks any widened part of the sole to the conformation or to the deformation of the feet of the user.

Abstract: A sole (6) for anti-slipping shoes of the type including foldaway anti-slipping elements (12) arranged in the face of the sole that will come in touch with the ground, characterized in that the anti-slipping elements to increase the adherence to the ground are secured to rigid or semirigid supporting members (10) that are hinged to the sole so as to be lifted from the same by rotation like a flag by at least 180° with respect to a symmetry axis other than the axis of hinge/lifting from the shoe sole and not parallel thereto. Each the supporting member being housed during the use of the sole in its own single recess or groove (8) arranged in the sole portions.
