Application illed July 30, 1921. Serial No. 488.7%3-

The objects of my present invention are to improve the sole construction, particularL ly in the matters of wearing quality and actual comfort to the user. n

Brieiiy, the invention consists 1n the present 1disclosure of a pair of sole members stitched together about their edges and Ia pad or cushion of material having the characteristics of natural cork interposed between the sole members and within the line or lines of stitching connecting said members. y

Other features of the invention will appear as the specification proceeds.

Figure 1 in the accompanyin idrawing isa longitudinal sectional viewA o ashoe embodying characteristic features of the invention.

` Figure 2 is a bottom plan `view of the partly completed shoe with the cork pad or cushion applied to the under surface of thel inner sole.

Figure 3 is a bottom plan vieiwr of the completed shoe with the pad or cushlon 1ndicated in' dotted lines as covred by the outsole. y

In the construction illustrated, 5 designates the up er, 6 the inner sole-secured to the lower edlges of the upper by a row of stitching 7, and 8 the outer sole secured `to the inner sole and to the upper by a rowof stitching 9, all three parts beingl further secured together in the casesliown by a row of stitching 10 passing through the welt 11.l y

12 designatest-he pad or cushion interposed between the inner and outer soles beneath the .forward or ball supporting. portion of the shoe, said pad being shown as.

having a flat upper face in engagement with the under surface of-the inner sole and beveled edges 13 forming inclined shoulders over which the outer sole conforms.

It will be seen from Figure 1 that this thickening of the sole provides a lbulging projection forming a contact and wearing pad beneath the ball of the foot. The insert 12 is usually constructed of resilient natural cork and it therefore operates in the arrangement shown to cushion the shockor jar 4onthe ball of the foot and this cushioning of the impact, I find, very materially adds to the useful life of the sole. This cushion of live elastic cork aids in promoting a light springy step.y in the wearer. 1t will also be noted that the strength of the shoey is not lweakened by passage of the stitching or other securing means through the cork insert.

'What I claim is:

1. In a shoe construction, a flat faced outsole. and a fiat faced insole, a row of stitching securin said outsole and insole together and a flat aced resilient padrinterposed between and restin against the flat upper face and the `fiat un er facey of the outsole and insole' respectively; said ad being arranged within the space boun ed by said row 'of stitching and free of such sttching and havlng the marginal edges of its undersurface bevelled to conform the outsole to a'nincline thereover.

2. In a shoe construction, an outsole and an insole, a row 'of stitching securing said members together and a resilient pad betweensaid .outsole and .insole and within the s ace bounded by said row of stitching and ree of such stitching, said pad havin(lr a fiat up er face presented to the insole an( havin t e lower face thereof beveled about the e es to conform the outsole to an incline t ereover, whereby to outwardly bulge that portion of the outsole overlying said ad, said pad and the bulge produced therey being located substantially at the ball supporting portion. of the foot.

In a shoe construction, the combination with an Vinsole and an foutsole, of a pad of cork-like material interposed between said insole and outsole of less area than the same and confined substantially to that `portion of the sole foot. 4. In a shoe construction, the combination withl an in'sole and an outsole, of a pad of cork-like material interposedbetween said which supports the ballpof the.

insole and outsole of less area than the same EDWARD J. MMSET.
