This invention relates to improvements in footwear andv more especially to shoes andl slippers of the general type having a forepart of upper which is stitched to a sock-lining or flexible in'- sole element all around the forepartwhile the upper is free of a last, after which a last is' inserted preparatory to lasting of the rear part of the upper and the placing' thereon of the base structure in secured relation to the upper. In particular, the invention provides suon a shoe or' slipper which can have a soft-sole and lightly flexible forepart and a relatively stiff and stable rear part providing adequate and effective support for the arch and heelinuse of the article;

It is an object of the invention to provide a shoe orA slipper structure having the forepart of upper stitched to' the edge of a sock lining all around the forepart and having the rawstitched edges of upper and sock lining concealed by a binding strip turnedv over said edges andv stitched thereto in a'proiectingrelation, simulating a welt, a platform and heel base unit being secured below the sock lining andl upper with the said binding visible all around the plane of' their cleavage at theforepart of the article.

Another object is to provide a shoe or' slipper structure having a soft-soletread element facingr the under side of al platform' element andhavihg a binding strip secured to the soft-sole element and turnedrv over the edges ofy the forepart of the platform, the stitch: line o'f` said softes'o'le element and its binding stripbeing' drawn'o'ut of-` the tread plane, ofthe article,- at its forepart;

Still another object is tor providera soft-'sole forepa'rt' in a shoe or slipperv in which the softsoletrea'd element issecured to" the forepart of a platform element only" by a binding strip on the soft-sole element, and' said platform. and1 softsol'e': element' both are secured,` to a pre-stitched `iorepartvof upper only'bythev same said binding strip onv the soft-sole element.

A further' object isv to provide' a pre-stitched slip-lasted' forepart of shoe upper with a softsole treadA elementi associated therewithf and'. a platform element loosely encased between said forepart of upperv and said soft-sole tread' element.

It is, moreover, m'y purposefand object generally to improve upon prior shoe and slipper constructions.

Figure Gis a top plan view ofthe platform ahfd heel unit used in the shoe' structure' of; Figure 5; Fig-.ure 'l is a fragmentary' cross-seet'ionalv view showing the upper, sock" lining and binding strip all stitched' together prior to4 association With a base structure; and

Figure 8 is a cross-sectional View on lin'e'B-S' of Figure 5, showing' the" upper structure'of Figure 7 cemented to a platfor'rn and heel unit like that oFigjure 6.

Referring to the" drawings; the' embodiment of my invention as shown in Figs. 1-4 comprises an upper IU whose forepart" is stitched as at I2 al1 around' the forepart 'ed-geto a sock lining |42, or other suitabl'yflexible insole element, prior t-o insertion of a` last inthe upper; The' edges of the upper and sock' lining'a're brought together as best vseen in Fig. 4 withtheir raw edgesv exposed, en-

abling the ,stitching at li2 to be accomplished quickly and e'asily'just aroun'dthe'forepart, leaving the rear part of the sock lining free of the upper so that" a last' conveniently' may loe'` slipped into the forepart betweenk the unattached rear parts' of' upper and' sock lining, after which said rear part of the upper' may be positioned` over the rear part of the ,last andv be regularly lasted to therear'part of the sockA lining. n

Accordingl to' the' invention', a platformY and heel' unit indicated: generally at l6` is pre-'formed by association and securement t'og'etherof afull length platformy element l 8 and' oneL or more heel 'lift elements which may bejli'ft laminations 20,

22- and 24' as shown, or maybe any` other unitary type" 0f 11661k e'leI'nn' Such' als 2J Solid Wedge heel lift arrarigedl above or' belo'wfthelplatfrinf element H3r or a unitaryI Cubanor other heell arranged under the platform element In-the' drawings, the heel lifts=are pre-formed matted" iibre laminations hav-ing their marginal edges bound with fabric-strips 26, the lift ZII-y extending' into the shank region of the shoev and contributing shank curvature( The'platfomn element 8'?, asV shown,` similarly is ofi matted fibre withi't's-marginal edges' bound as' at f 28.V

It isa feature of the Vin-ven'tionthat a soft-isole tread element 3Ucoverstheunder! surface of the platform eler`r1er'1tl I'8 throughoutitsforepart,y area, and'E hasf prelinflinarilyv` stitched thereto, as` at 32, all` around its foreparty edges a-` binding strip" 34 of|` fabric OI other Suitable flexiblenaieial..V This stitching at 32 may be accomplished wlciilethe soft-sole tread element'is'free ofi the platform, theI binding stripV` 3W being laid" againsty the marginal edges of thetreadelement '-on-i-tsside`=wnich will be exposed; andstitche'd in afus'ualfmann'e'r.

AssumingV that a la'st has beenV slipped." into-'the pre-stitched' forepart of upper Hl; and" thatthe r'e'anpart of the upper has been" lasted aspreviouslyjdescriped; then platform and heel unit t6 A may" be' laid' in' place',l after which the" soft-sole g2 Y .i laeempr treed element so, with its attached binding strip 34, is laid over the forepart of the platform and the binding strip 34 is turned over the forepart of the platform element I8 so that its marginal edge may be superimposed upon the under side of the Vpre-'stitched edges of the upper and sock lining, as best seen in Figs. 3 and 4. The binding Y t strip 34 is'drawn tight to provide a smooth arid-1y tight tread surface, and also to draw the stitch-Nv line at 32 a little over the edges of the platform l `thereby to bring the binding strip 34 wellY out Y j of the tread plane. A binding strip 36 next is t lead over the exposed raw edges of the upper,

sock lining and binding strip 34, and all are stitched together as atY 38`V all around the forepart, therebyvtoneffect securement of the Yplatform forepart and its soft-sole tread element to the upper and sock lining with the edge binding stripv 36 simulating a weltapproximately in the E.; i place of cleavage between theplatform and the sock lining.

With the above Vdescribed forepart'structure, no

cement or other securement between the plat form and its tread element or between thesev ele- The rear part of the Vplatform and heelunit may be cemented or otherwise secured in placeV l below the lasted rear part of the upper, thereby 1 to provide a relatively stiff and stable shank and V; heel structure capable of providing adequate and effectiveV support for a foot in use ofthe shoe.

The soft-sole'tread .element 30 has an integral rearwardly extendingV strip3l which effectively maybe cemented in facing relation to the under 'surfaces ofthe platform Vand heel unit. It may i l constitute the wearing 'surface for the heel, Aor

a top lift 40 may be provided as shown in dotted t i Voutline in Fig. 3. Y Y

In theY form of my invention /shownin Figs. Y 5-8, 4the soft-,sole tread'element 30 has the same binding strip 34 stitched thereto as at 372, but Vthe `binding strip 34 in Ythis' case is turned over Y.,

the forepartedges of the platform I8 andV cemented or otherwise secured tothe upper mare ginal surface of the platform prior toV association ofthe platform with the upper.Y With thiseconstruction, the platform andheel unit with the soft-sole tread element V30 secured thereonV may be completely assembled prior to placing it r againsttherupper, andthe unit throughout both forepart and rear part preferably is cemented in place.V

sertion of .a last inthe upper and' this binding simulates a welt aboverthe platformall Vvaround the forepart similar to the effect in -the first described form. f Y
