One of the methods used by housewives, due to secrets revealed by their grandmothers , is that of letting the aluminum foil rest inside the shoes in the evening so that they expand.
First, you need to have some aluminum foil with you and roll them into a shape that can fit inside your shoe. Then immerse the leaves in a little alcohol and insert them inside the shoe.
We must be careful not to damage the shoes with alcohol and therefore, before continuing, make sure that it does not completely damage our shoes otherwise we would have to throw them away.
Once this is done, we leave the aluminum foil impregnated with alcohol inside our shoes overnight and if necessary, for a whole day and we will see how the evaporation of the alcohol will swell our shoes.
