Description

  

   <EMI ID = 1.1>

  
 <EMI ID = 2.1> According to one of the known execution modes of this

  
 <EMI ID = 3.1>

  
sharply in the articulated area of the sole and

  
 <EMI ID = 4.1>

  
of gravity of the arch, vere the heel

  
examination of the bearing surface of a left abacus sole shows a more or less Z-shaped front narrowing, in the water of a right shoe, said

  
 <EMI ID = 5.1>

  
The upper of the shoe extends beyond the sides forming the

  
 <EMI ID = 6.1>

  
 <EMI ID = 7.1>

  
is reduced in the articulated area, it is even smaller than the contour of the foot, which causes a sagging of the upper towards the narrowed part and thus exposes it to

  
 <EMI ID = 8.1>

  
 <EMI ID = 9.1>

  
lie quickly in this area, however this cut of

anterior tie of the sole.

  
The invention * everything. given for goal of perfection-

  
 <EMI ID = 12.1>

  
 <EMI ID = 13.1>

  
flexibility factor is essentially changed.

  
 <EMI ID = 14.1>

  
terized in that it meets / two following criteria! a) the face of the sole in contact with the ground is retracted - <EMI ID = 15.1>

  
heel part, i.e. in the articulated part, l <EMI ID = 16.1> around the foot *

  
The accompanying drawings show that the sole

  
 <EMI ID = 17.1>

  
It emerges from the above discussion that the thick

  
 <EMI ID = 18.1>

  
dull part of the articulated part must be as weak as possible, for example, it must not exceed one millimeter,

  
which does not present any difficulty for manufacture, when the sole is made of rubber or similar material. ,. It does not matter whether the sole is provided with a heel, whether it has two assembled layers or whether it is thinned in the articulated zone.

  
In the central part of the articulated area, the thickness of the sole should also be relatively

  
 <EMI ID = 19.1>

  
the central part of this articulated zone may not exceed that of the front part or of the heel part of the sole.

  
. If the sole is made up of two layers, the one resting on the ground therefore, the sole itself can be leather and the layer on the side of the foot can be made of a more elastic material, for example rubber. rubber all the more so since a second sole is usually placed on this layer, which will be made so that the heel part is flexible relative to the front part.

  
The sole can also have three thicknesses ^ <EMI ID = 20.1> its anterior part, as indicated by the broken line on fig 1.

  
 <EMI ID = 21.1>

  
here the sole of a left shoe has, in its articulated part 3, a Z-shaped narrowing, because the edge

  
 <EMI ID = 22.1>

  
drawn, attracted to the middle 6 of the joint as indicated

  
 <EMI ID = 23.1>

  
The surface of the sole in contact with the foot is in the articulated zone, of dimensions such as the

  
 <EMI ID = 24.1>

  
dique section II II, fig. 2, the sole can also, at least in the articulated zone 3, be formed of two layers, the two layers being assembled, by gluing for example.

  
The sole could also have three thicknesses as indicated in section III III of FIG. 3.

  
 <EMI ID = 25.1>

  
 <EMI ID = 26.1>

  
This can be achieved by using trump-

foot circumference.
