A further object ofthis invention is to provide foot coverings including a heel portion and a toe portion, a tongue on one portion and a socket on the other portion for slidably receiving the tongue and interengageable means on the heel and toe portions for :fixing` the position of one portion relative to the other portion.

Still another object of this invention is to provide foot coverings including portions which may be adjustably positioned relative to each other in their length and in their breadth, togetherwith means for fixing the portions in their adjusted positions.

Yet another object of this invention is to provide a slipper including slidably interengageable toe and heel portions which may be moved relative to each other to adjust thelength of the slipper together with means for fixing the interengaged portions in any one of a plurality of selected positions, the toe portions being adapted to be removed from the heel portion and to be used as mules.

Other objects of this invention will in part be obvious and part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.

In the accompanying drawing, in which is shown various possible illustrative embodiments of this invention:

Fig. 1 is a side elevational view of a sandal embodying the invention and illustrating a further modification thereof;

.Fig 2 isa side elevational View of a sandal embodying the invention and illustrating still a further modification thereof;

Fig. 3 is a side elevational View of the sandal shown in Fig, 2 and showing the opposite side thereof;

Fig. 4 is a side elevational view of a sandal embodying the invention and illustrating a modicationthereof.

In Fig. l. is shown a sandal or slipper 60. The same comprises a heel portion 6| which includes a fabric upper or quarter 62 stitched at its lower edge to a heel 63 of leather or the like. A fabric insole fili is stitched to the sides and rear of heel 63, leaving the front edge of the insole free of the heel and forming an opening 65 therebetween. The upper 62 also comprises forwardly extending flaps 55 provided with a row of outwardly extending male detachable fastener elements 67.

The slipper further comprises an instep and toe p'ortion 19, The same includes a sole 'il of leather or the like, the outer edges of which is stitched a fabric vamp l2. Leather reinforcements 15 are stitched to the outer surface of the rear portions of cap 72, adjacent the sole Tl. The fabric i2 is provided with a row of detachable female fastening elements it, which are disposed opposite each of the leather reenforcements 15. The fastening elements `I6 are detachably engageable with elements 6l on heel portion 6|. The sole 1| includes a rear portion Tl projecting beyond the rear end of the cap portion 12. The sole portion Tl forms a tongue receivable in the opening in heel portion 6i. It is apparent that the toe portion 'lil may be slidably positioned lengthwise with respect to heel portion 6l with the tongue 'l1 moving within opening $5. The heel and toe portions may be retain-ed in their adjusted position by engaging fastening elementsv 16 on the heel portion with fastening elements 67 on the toe portion. The fastening elements may be readily detached to permit readjustinent of the heel and toe portions.

In Figs. 2, 3 is shown a slipper 8e embodying the invention. The same comprises a heel portion 8l which includes a leather heel 82. A fabric upper or quarter 33 is sewn to the heel B2. A fabric lining 8d is stitched at its peripheral portions to the upper face of the heel 82 at the side and rear edges thereof. This provides an opening 85 between the lining andthe heel at 4the front edge thereof. A leather reenforcement 85 is secured on the rear upper portion of quarter 83 by spaced parallel'lines of stitching 81 which provides an open passage 88 between the stitch lines. Y

The slipper 8i! further comprises a portion 90 which includes a leather sole 9| padded on its upper surface and to which is stitched a fabric upper and toe cover 92. A leather toe cap r93 may be stitched to the forward portion of toe cover` 92. The leather sole 9| includes a rearwardly extending portion 94 which forms a tongue receivable in the opening 85 in the heel portion 8|. Extending from one side of fabric upper 92 is a strap 95 of fabric or the like which is adapted to pass through the passage 88 on the heel portion. A short upwardly extending strap 96 interconnects the lower edge of upper 92fand strap 95. Extending from the opposite side of upper 92 is loop 91 with its ends stitched to the upper. is mounted on loop 91. The free end of strap 95 is provided with a buckle |00 which may be adjustably mounted on the strap and is releasably engageable with the bent back portion 99 of catch 98. The buckle comprises a rectangular member |0| with a serrated inner edge |02 on one side thereof. A member |03 is slidably mounted on member |0| and is formed with a serrated edge |05. It is understood that the free end of strap 95 may be threaded around the slidable member |03 of the buckle and frictionally engaged between edges |02, |05 to retain the same in a predetermined position.

It is apparent that the portion 9 of slipper `30 may be adjustably positioned relative to the heel portion 8|, with the tongue 94 slidably received in opening 85. The strap 95 together with catch 98 and buckle |00 provide means for xing the adjustable portions relative to each other in a predetermined position on the foot. The catch and buckle provide for quick attachment or detachment. Additionally, portion 90 may be entirely removed from heel portion 8|, by removing buckle |00 from strap 95 and slipping the strap through the passage 88 on the heel portion. In this case, portion 90 may be used as a mule provided with the strap 95 and the catch, buckle members 98, |00. The tongue portion 94 is of suiiicient length to provide support for the heel of the wearer.

In Fig. 4 is shown a sandal or slipper H0 embodying the invention. The same is entirely similar to the slipper shown in Figs. 7 and 8, except that the strap 95 and catch, buckle members 98, |00 is replaced by eyelets ||2 on opposite sides of portions 8|a, 90a together with lacing ||3. Here too, the portions 8|a, 90a may be adjusted lengthwise and retained in adjusted position by lacing ||3. Also, the portion 8|a may be removed from portion 90a, and the latter used as a mule. The lacing |;|3 may then pass around the heel of the wearer to engage the opposite sets of eyelets It will thus be seen that there is provided a n device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.

The slipper ||0 shown in Fig. 4 may be pro- .,vided with Va stiffened U-shaped arch support A catch 98 with a bent back portion 99 member ||5. The member ||5 is secured to the rear portion of the sole of portion a with the upstanding walls ||6 providing a covering means for the gap between portions 8|a, and 90a. It is apparent that such U-shaped arch support may be used in the other slippers hereinabove described, and shown in Figs. 2, 3 and 4.

Having thus described my invention I claim as new and desire to secure by Letters Patent:
