This invention relates to a novel form of footwear-or shoe designedparticularly for infants, though advantageous for use also by others, and has for its general object to provide a simple, economical and thoroughly practical form of shoe characterizednot only by its attractiveness but also the security with which it will be held to the foot, a feature generally lacking in infants' footwear.

The heel of an infants foot is both narrow and undeveloped at the back, so that it cannot be fitted by the usual soft shoe, for example, a knitted bootee, even though the shoe may be tied about the ankle. So undeveloped is the heel that the shoe will tend to slip down about the heel and off the foot. In accordance with the invention I have accomplished asecure and. yet comfortable retention of the shoe on the foot, by tying the shoe not only about the ankle, but also about the arch of the foot, all in a manner such that the shoe is so held to the arch as to resist slippage down about the heel and is held against slippage forwardly off the wider portion of the foot.

The invention further contemplatesmaking a shoe of the character indicated from a single sheet of material such as felt, chamois or the like, so formed as to be capable of die cutting from'thesheet stock and at low production cost.

Specifically; the sheet stock is cut into an'elon gated shape-including an intermediate pottion' forming the sole and. which is best tapered to-ward the heel end, a pair 6 of tongue and heel flaps hinged at the front and rear ends of i the sole portion to fold inwardly thereof, and a pair of side fiapshinged to the side edges of the sole to fold upwardly in overlapping'relation with the tongue and heel flaps. By an arrangement of registering string-receiving openings in the side and heel flaps, and also if desired in the sole portion, an appropriate string, such as a single ribbon, may be passed about both the arch and ankle portions of the shoe to hold the shoe securely on the foot.

All the above mentioned features and objects of the invention, as well as the details of a typical and illustrative embodiment, will be explained to best advantage in the following description of the accompanying drawing, in which:

Fig. l is a general view showing the tied shoe in perspective;

Fig. 2 is a" vertical section in the plane of line 2-2 in Fig. 1;

Claims. (01. 36 -41) Fig. 3 is a view similar to Fig. 1 showing-th strings and flaps in loose and open condition to more clearly reveal the flap relationship; and

Fig. 4 is a plan View of the shoe blank as it is cut from sheet stock.

Referring first to Fig.4, the shoe is formed of a suitable soft and flexible sheet stock 10 such as felt, suede or other appropriate material. As cut from the sheet stock, the blank comprises a longitudinally intermediate portion H which forms the sole of the shoe, a forward toe or tongue flap l2 the length of which may be approximately the same as the length of the sole section II, and a cut in the form of substantially straight edges at [6 and curved side edges I'l.

Extending laterally from the sole section II is a pair of side flaps l8, the edges I 9 of which curve rearwardly from the tongue hinge line I4 toward the heel flap l 3, the rear edges 20 of the side flaps extending inwardly to the hinge line l5. These side flaps are adapted to be turned upwardly from the sole section along the sides of the latter deffined by the hinge lines 2| which converge rearwardly fromthe hinge line M to the rear hinge 5 line I5, thus giving the shoe a progressively narrowing width toward the heel.

The tongue, side and heel flaps are provided with string-receiving openings or perforations, preferably in the form of parallel slits 23, 23a, 23b, 23c, 23d and 23a, positioned as illustrated in Fig. 3 to accommodate thestrings 24 and 25 which preferably are in ribbon form. By reason of the string extent beneath the sole section I I, the latter may also contain a pair of string-accommodating'slits 25d. I l h In shaping the shoe from the stock blank,

the tongue flap. I2 is turned rearwardly from 3 the hinge line M, with. the sides of the flap I! in-turned, and the heel flap I3 is turned up wardly along hinge line IS, with opposite side portions of the heel fiapturned forwardly, all 'as clearly illustrated in Figs. "1 and 2: The side flaps l8 then are turned upwardly along the hinge lines 2| into overlapping relation with both the toe and heel flaps, thus completing the form and shape of the shoe. By tying string which is inserted through the slits 23a in the side flaps,

the tongue flap may be held in place independently of the string 24. For the purpose of securing the shoe to the foot about both the heel and ankle, the string 24 is brought beneath the sole section II through slits 25a, thence upwardly at the sides to be crossed over at 21, from which the ends of the string are brought around the sides of flaps It to be tied at 28.

By reason of' the rearward taper given the sole portion II, the shoe is caused to snugly fit the characteristically narrow infants heel. Then because of string 21 being tied about boththe arch and ankle, the shoeis held comfortably and yet securely to the foot since any tendency for slippage down about the heel is resisted by the shoe being held to and about the arch.

It is contemplated that the shoe may be manufactured and distributed in the completely assembled condition of Figs. 1 and 2, or that it may be supplied inthe form of the Fig. 4 blank with. the strings furnished for insertion by the purchaser or user, or that the strings may be at least partially inserted through the slits to facilitate complete assembly and final threading of the strings by the purchaser,

I claim:
