IVHTHHN M V/TT BY 2 6 'f-ITTOPNEY N. V. LEVITT SHOE LAST Feb. 2, 1943 2 Sheets-Sheet 2 Filed July 24, 1942 T mv NM M T W H TTORNE Y Patented Feb. 2, 1943 A'E'ES OFHCE 1 Claim.
The present invention relates to improvements in shoe lasts, one object of the invention being the provision of a last through the medium of which the orthopedic shoe, such as is shown and described basically in my U. S. A. Letters Patent No. 2,224,458, granted to me December 10, 1940,
can be made, it being understood, however, that this last is used for the completion of a shoe embodying the features of said patented shoe without the use of internal or external inserts as there shown.
This last is so designed that a shoe made thereon, will be provided with an internal elevation along the outer longitudinal arch of the shoe, that inclines in opposite directions from a point of the shoe that would lie substantially below the cuboid bone of the foot of the wearer, and that also inclines inwardly below the os calcis, so that the os calcis is held against a sidewise rolling or rocking movement, which directly results to prevent the lowering of the susten taculum tall and provides a transverse arch support that prevents pronation of the foot.
Therefore in order that the invention may be fully understood and its many advantages appreciated, attention is invited to the accompanying drawings, in which:
Figure 1 is a side elevation of the last taken from the inner side.
Figure 2 is a rear view of the last.
Figure 3 is a bottom plan view of the last.
Figures 4, 5, 6, 7, 8, 9, 10 and 11 are crosssections taken respectively upon lines 4-4, 55, 6-6, 'l-'l, 88, 9-9, l.0l0 and llll of Figures 1 and 3.
Referring to the drawings, G-G designates a base line upon which the last I rests, CC the vertical central longitudinal line of the last, and in relation to which the several formations on the exterior of the last are related. The last proper is provided with the heel portion 2 shaped to form a cupped heel receiving portion in the shoe, the toe portion 3 and the arched portion 4. The portion of the last adjacent the heel portion at the outer longitudinal portion of the last is provided with a slightly upwardly bowed ribshaped portion 5, which provides in the shoe a support for the outer longitudinal arch of the foot of the wearer, the rear portion 6 extending transversely of and into the cupped heel, while the forward end terminates, to provide with the inner portion 1, a slight recess 8 intermediate between the inner and outer sides of the bottom of the last, at what may be termed the ball of the foot.
The heel portion 2 provides in a shoe a cupped heel receiving portion at a point that would fall directly below the lowermost portion of the 0s calcis bone of the wearers foot, and as the portion 5 is so shaped along the extreme outer longitudinal arch of the last, it will provide as before stated in the shoe itself, an elevation that is slightly bowed intermediate its ends and inclines in opposite directions to terminate at the os calcis rearwardly and adjacent the distal end of the fifth metatarsal bone at the forward end. Also as this elevation inclines inwardly and terminates in the heel portion, there is provided a support for the os calcis so that it cannot rock or roll inwardly, therefore providing a support that will insure a natural working manipulation of the foot of the wearer and consequently a shoe having the desired natural support for the foot, so
that pronation of the foot is prevented and there' fore the causes of Mortons toe is removed, and a shoe of great comfort will result.
With this design of a shoe last it will be noted that there is a complete transverse support of the metatarsal arches not heretofore provided for in the common lasts.
The modern construction of the present last makes for a shoe that will permanently hold all of the arches of the foot in permanent natural position, so that there will be an end of prevalent foot troubles to wearers of shoes made on this last.
What is claimed, is:
A shoe last having a convex heel seat, an integral depressed portion extending forwardly therefrom as far as the junction of the shank and ball portions thereof, the depressed portion being of an extent to underlie the external longitudinal arch of the corresponding foot to counteract a tendency to pronation, and an enlarged portion adjacent the internal ball portion of the last.
