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.
