This The numeral I0 represents the upper of a shoe, stitching is important in that it maintains the the sole being indicated generally by the numeral elements 29 and 30 in proper superposed and l2. To the sole are attached as by stitching I3 registered relation. The heel piece 35 is then 55 secured to the strip 29 as by cement and the shoe is then lasted by hand. In this process the upper l0 is temporarily tacked around under the composite sole part S as shown at 32 in Fig. 1 and the turned in portion 32 of the upper is then cemented to the canvas part 29. In this process the toe portion of the shoe must be wiped over by machine and in order to withstand such treatment the reinforcing element 38 is desirable. The sole member 25 is then laid on and cemented to the adjacent parts and the stitching 28 is then applied. The metal plates and the sole and heel taps are then secured by the stitching I3 in such embodiments as employ cleats.

It will be understood that Where the shoe is provided with cleats, the longitudinal stitching 40 may be eliminated inasmuch as the cleat fastening devices will serve to maintain the elements 29 and 39 in proper relation. My invention is applicable both to cleated and uncleated shoes.

In all embodiments of my invention I have provided a shoe of adequate strength for all practical purposes while at the same time such shoes have greatly enhanced flexibility and reduced Weight, thus adding greatly to the comfort K and eiciency of the wearer.

Various changes coming Within the spirit of my invention may suggest themselves to those skilled in the art, and hence 1 do not Wish to be limited to the specic forms shown and described or uses mentioned except to the extent indicated by the appended claim, Which is to be interpreted as broadly as the state of the art will permit.

I claim: In a shoe, a composite insole comprising a strip of upper leather, a strip of substantial and relatively exible, light Weight fabric secured thereto by adhesive and by longitudinal stitching adjacent the central portion of the insole to prevent relative slippage of said parts, and a thin and relatively stiff U-shaped member formed of light Weight material secured between said parts adjacent the toe portion and having its outer edge substantially coextensive with the outer edge lasting operation.
