therethrough, the heel piece being adapte to beplaced betweentheouter sole` and/a combination middle andvinner sole lsosthat will effectively engage the cushioning pad the-adjacent faces of the combination mid-4 die and inner sole and the outer'and therebyform an effective cushioning support forV the heel of the wearergthe heel piece.` itself functioning to form an effective the entire heel Of'theWearer. 1j
Another important obj ect of my invention isthe-p'rovision of the combination middle'and inner `sole fori receiving theupper end ofthe cushioning pad so as to permit the niaxin'ium aniountlof` beneiitto be obtained: from the AVcushioning pad with` a minimum amount. of material between the pad and the heelof the wearer.
Anothersalient object of" my invention is the provision-.of a resilientf'heel piece adapted to bepermanently :placed betu'reen'the combination middle andinner sole and outer soleof a shoe, the resilient heel lpiece carrying-fa cushioning padrso disposed and arranged as to form ineffective cushioning support for he calcaneumfbone ofy a foot of-the wearer of the shoe.` ,A still further object of "my invention: is to provide a cushion heel support or kpocket for the calcaneum bone to restinWhen :walk ingpof the above character,` whichwill be durable and kefficient in use, one that will be simple Vand easy'fto manufacture, and one be incorporated with a conventional shoe ata low cost. r
With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described,

Figure is` a view similarto Figure l illustrating the slightly modified form of my invention shownin FigureV 4,- and Figure 6 is a detail fragmentary prespective,r Viewv of the heel Vpiece carrying the resilient pad. u i 4 :Referring to thedrawing in detail, wherein similar reference characters designate corresponding Vparts throughout the several views, tliefletter A i, generally indicates a shoe sole c'onstructedfin accordance with my invention and as shownithe shoe sole A embodies a combination middle and inner sole ldand an 'outer solell. j j The combination middle andinner sole 10 is .treated inV the ordinaryway to receive the lining and upper of the shoe and in' ac- Vcordance vwith my invention the heel portion l2 thereof haslowei face provided with a yrecess 13leaving a relatively thin section kof leather le atlthe central heel porition thereof. u
, One-ofthe-'salient features of my invention isthe provision of the ycushion heel piecel which is shaped to conform to the construction or configuration ofV the heel -portions of the combination middle and inner sole 10 and outer sole 11 and the bodyk portion of the cushion heel piece 15 can be Ythe combination middleandV in.

material instead of M n sponge rubber and other material instead or use other resilient leather for the body portioirof thelheel Widely varied `and inA Figures 1 to fin c Velusive I have shown 'the pad of a circular 2 figuration of a piece.V -This pad.. of resilient material v18 preferablyextends abovev and below the opposite faces v.of the heel piece and the `upper projecting portion of the, resilient pad is received within they cavity 13.of the, heel portion 12 ofthe' middle sole 10.;- 'These parts are Vall cemented or `otherwisefa'stened together inv the finished sole, so .as to form asubstantially unitary article.
'The shape of-theresilient pad`18 cany be In Figures el, 5, and 6,- I have-shownnthis pad'of shape toconform- 'to the usual conshoeheel andthe pad in Figures l to G inclusive indicated `by the reference character 20,., It is to be noted.-
that the pad in this modified form also eX- ten'dsmaterially above and below" the opposite faces of the .heel piece 15 and while I have specified that the combination middle v and -inner sole and `theouter sole are `cemented together, it is to be understood that the same canbe also sewed together."v
`- By my improved construction the vcushion heel can be readily incorporated in the The cen-- j ofV the 'heel piece, it is tovbe understood that vthese yingva cavity 'projecting .upper end 0f soles, said heel j ing acavity in its j material over .the pad.

of beneiitffrom the cushioning pad. lFurther the thinpiece of if material ll'is of a relatively flexible nature due to the thinness thereof and thus will not cause any discomfort to the wearer, and
will effectually prevent what istermed by orthopedists as oscillating or rotating heel bones which the direct'cause of distorted heel seats in spring heel shoes for children and; crooked heels on shoes worn by adults, this .being accomplished by reason of the fact that a liexible cushion is provided whichwill tend to effectively hold the heel bones in proper anchored position, the heel bonesnot having a tendency to slip or rotate 4within the `heel. of Vthe shoe.
