(01. 36-11) This invention is for a shoe construction and sisting shoe is formed because the sole and part has for its main object to provide a shoe in which of the upper is formed of strong sole leather and the sole, the toe box, the counter, an arch supin one piece. 7 port, a heel seat, and part of the upper are-all By the term sole leather" as usedthrough- 5 formed in one piece.

At the arch support portion on I tion is less costly to construct. A tough wear rethe inside of the foot the molded leather extends higher as indicated at n by the dotted line in Fig. 2.

As is clearly seen from Fig. 3, the molded lower extends upwards at the arch to the point of inward curvature. By this is meant the point at which the upward extension of the tangent to the curve at said point is inwardly directed.

When the last periphery begins to narrow down the leather is compacted or crinkled or pieces may be cut outat suitable places. The upper portion of the counter narrows considerably over the last, but crinkling at that point is practically avoided because of the relatively long sweeping curve downward toward the sides of the body l6 and also because most of the slack there created maybe taken up at these long sides.

After the leather becomes set the crinkled portionmay be cut away at l8 as shown by the dotdash line and the molded lower may then be removed from the last.

- The rest of the upper l9 to complete the shoe may be of any suitable material and may be joined to the lower in any suitable manner.

When finished, the molded lower of the shoe of this invention is permanently set and will not lose its shape. It is however sufliciently flexible to be comfortable to the wearer and yet provide full and proper support to all parts of the foot. invention lends itself to a lip channel stitching between the lower and the upper on the face of the shoe because the heavy sole leather joining the upper is sufficiently thick at the joint to be so stitched. 'This method of stitching the l pper to the lower is illustrated on Figs. 3 and 4.

Asin the usual lip channel stitching a lip 20 is cut by a knife preceding the stitch 2| which joins the lower to the upper. The lip then covers the stitching and may be sealed down so that the stitching 'is completely invisible. This has heretofore not been done in the art to applicants knowledge.

It is also feasible to shave away part of the thickness of the sole leather at the portion forming the upper part in order to make a lighter and more pliable shoe. Whenever strength is essential, as on the sole, toe'box, arch support and counter, the leather will be left at its full thickness.

Women's, men's and children's shoes may be made according to this invention. For added thickness, as in the case of a sport shoe, or, if the sole becomes worn when in use, an additional sole may be attached to the shoe in any well known manner.

It will be noted that a shoe constructed 8.0- cording to this invention as clearly described above -will accomplish all-of the objects and have all of the advantages as enumerated above.

We do not wish to be limited to the exact disclosure as herein shown, but all equivalents as may fall within the scope of the appended claims are meant to be included,
