'This invention relates to sportfshoes, and particularly to a Vsport shoe of sandal type.

VOne of the objects of the invention is .to produce a sandal of simple construction,which will be most useful as a hot weather sandal, and which is so constructed that in walking it will operate to develop air circulation at the sides of 7 the foot.

` A further object of the invention .is to produce footwear having advantageous features which may be embodiedin a sandal that can be readilyr constructed without necessitating the employment of a last, and in which the size or shape of the sandal is "determined by its sole or platform.

A further .object of the invention is to construct footwear, .for example, asandal in such .a way that when the weight of the wearer is-exerted upon the ball of the foot in walking, theflatera'l pressure exerted by .the side ofthe foot upon the upper, will be somewhat relieved; in other Words, lto provide `a certain expansibility for `the upper at the level ofthe upper face of the sole, at the same time insuring an effective securing of 'the upper to the .sole so as to insure that the sandal will maintain its original formv aftertbecoming worn. Further objects of thev invention will appear hereinafter. l The invention consists in the novel parts and combination. of parts to be described hereinafter, all of which contribute to produce an efficient sandal. f

A. preferred embodiment of the "invention is described :in the following specification, while the broad scope of the invention is `pointed out in the appended claims.

Inthedrawing:

Fig. 1 is a side elevation of a sandal embodying my invention.

Fig. 2 is a longitudinal section through the sandal illustrated in Fig. 1.

Fig. 3 is a longitudinal section through the' assembly, consisting of the upper and the mudguard ready to be secured to the sole or platform.

Fig. 4 is a cross-section taken about on the line 4 4 of Fig. 2.

Fig. 5 is a section through the sandal, taken about on the line 5 5 of Fig, 2, but showing only the right side of the sandal.

In practicing the invention, the construction shouldbe such that alongside the forward portion of the foot the upper is attached in such a\ way that it will have considerable freedom of lateral movement in walking, and this develops air currents around the vsides :of the foot; that keep it cool.y However, in .accomplishing this, `it

is necessary to provide, means forsecu-ring the lower edge of the upper to vthe-:sole at several points, in order to prevent the sandal v'or `shoe from giving the wearer thel sensation vthat itis too free or loose; in other words, to provide several fastening points at .the sides that will maintain the last of the sandal, therebyinsuring that the last and ilt` of lthe shoe will be maintained as the shoe is Worn continuously for a considerable time.

Referring-,more particularly ytov the parts, I'

-indicates the solcon-platform which may be `com-v posed .of any material, but preferably of felt `or similar cushion material. This sole or platform is rcut toa predetermined last, Iand :before .securing it to the other parts .of.;-the shoe, the vheel* block or wedge `2 is secured to the under side of the sole by cement vapplied at their meeting faces 3. v

1n Fig. 3 Ifillustrate the-.other 'parts of the shoe that are assembled before `rattaching the same rto the sole .and the heel. These parts in'- clude an upper 4 which'may, if desired,.be formed in one piece, .but which in the present instance is formed of two piecesda and 4b. The portion 4a Aof the upper .corresponds to the vamp of an ordinary shoe, .and i's made of .one `piece with a toeopening or gap*5, .and is preferably 'also formed with two. side Iopenings or gaps 16; The' piece 4b is a heel tug and is of =arc form as viewed in side elevation, with its narrowest width Aat the point '1 located at'the rear of the shoe, and in a position to engage the rear side of the wearers heel. This heel portion is provided with an adjustable instep strap V8 which may include an ordinary'lbuckle.Si,A the ends .of the strap being or connected together at an overlapped joint I2,

indicated by the dotted and full lines in Fig. 1, and preferably located on the inner side of the shoe or sandal. The upper sections 4a and 4b may be secured to the mud-guard by any suitable means. In.` the present instance, for this purpose I employ lacings I3', I4 and l5 stitching i these parts together.

The upper and lower edges of the mud-guard.

are providedwith a series of closely spaced narrow flaps I6 which are to be secured respectively to the upper and lower faces of the combined sole and heel 2 by bending the same over and cementing them in position. These tabs are, of course, not continued at the location of the lower edges of the two upper sections 4a and 4b, but in order to secure the mud-guard in position between these two sections, I provide a relatively large tab or flap I'I between these two sections at each side, and a, similar flap I8 toward the front, located so as to register with the side gaps or openings B. After the assembly illustrated' in Fig. 3 has been completed, the mud-guard is applied to the sole and heel 2 so as to completely cover the sides of the same, and is cemented or glued at any points desired, or continuously throughout the entire area, if desired. All of the relatively small naps IS are then cemented and pressed down onto the upper'and lower faces of the combined heel and sole, and at the same time the side extensions or iiaps II and I8 are cemented and pressed down onto the upper face of the sole. -The flaps I8 should be sufiiciently narrow at their roots to enable them to pass freely through the openings 6.

The secured flaps I'I and I8, and particularly the flaps I 8, assist in enabling the sandal to maintain its last, but in order to give additional means for maintaining the last of the sandal at the rear partof the upper section 4a, I prefer to provide flexible anchor means secured to the lower edge of the upper, and attached to the upper side of the sole by an adhesive. present instance, this means consists of anchor loops I9 (see Fig. 5) these loops are in the form of short tie members, and before being secured in position as indicated in Fig. 5, are set in place as indicated in Fig. 3, each loop being preferably formed with a large-body above, and with a na rrower .downwardly projecting tongue 20. This tongue is illustrated as extended down through one of the stitches of the lacing I4; and when the tabs and aps II and I8 are being cemented in place, the body portion of ythisl flexible staple is cemented down onto the .upper face of the sole while the tongue 20 is cemented against the side edge of the sole, and if desired, turned under the bottom face of the heel 2. After the assembly of parts illustrated in Fig. 3 has been attached to the sole and heel, a relatively thin outsole 2I is cemented to the under side of the combined sole and heel, and a sock liner 22 is applied to the Vupper side, covering all of the tabs I6 and the flaps I 'I and I8.

In examining Fig. 5, 'it should be understood that this view somewhat exaggerates the lateral In the dimensions of the connected parts near the upat this point the tongue 20 passes down securing this lacing to the side edge of the sole. The overlapping edge of the upper is, of course, held closely against the outer side of this exible loop.

AIt will be evident that in Walking, this loop I9 will oier considerable resistance to the lateral pressure of the foot, which would be exerted at about the location of the arrow 23.in Fig. 5. However, when the sandal is worn, it will be evident that there is considerable freedom of movement along the lower edge of the upper which ventilates the wearers foot and keeps it cool.

VOf course, at the side openings 6, increased ventilation occurs.

The lacing at I5 preferably includes an extension 2liV that extends downwardly and is secured through arsingle opening 25 at a point on the mud-guard, that is located at a lower level. This gives an additional point for distributing the pull of the lacing in addition to the upper lacing openings 26. 'I'his considerably increases the resistance of the heel section 4b as regards its connection to the mud-guard. In other words, this low anchorage assists in preventing the heel section 4b of the upper, from being pulled away from the heel portion of the sandal.

Many other embodiments of the invention may be resorted to without departing from the spirit of the invention.

What I claim is:

l. In a sandal construction, the combination of a sole, a mud-guard extending along the edge of the sole and attached to the under face of the sole, an upper having oppositely disposed gaps adjacent the sole, lacing passing through the mud-guard for securing the same to the lower edge of the upper, anchor loops passing around portions of the lacing at the inner side of the upper and secured to the sole, said mud-guard having extensions projecting through said gaps and secured 'to the upper face of the sole.

2. In a sandal construction, the combination of a sole, a mud-guard extending along and covering the edge of the sole, an upper with its lower edge overlapping the upper edge of the mud' guard, fastening means securing the upper to the' mud-guard, and anchor loops of exible material engaging said fastening means andsecured to the sole.

3. In a sandal construction, the combination of a sole, an upper unattached to the sole, a cover piece attached to the edge of the sole, lacing passing through the upper and cover piece securing the same together with loops of the lac-' ing located on the inner face or" the upper, and anchor loops of ilexible material distinct fromi the lacing attached to the said loops and secured to the upper face of the Sole.
