Description.

Heretofore, shoes have been constructed wherein there has been provided a thickened area or a padded portion in the region of the metatarsal arch of the human foot. This padded portion usually has been constructed by placing a pad between the inner and wearing soles of the shoe relying upon the unequal resistances of the insole andfoundation thereof to provide special support for the metatarsal arch. This has proved both unsatisfactory and inefficient owing to several reasons, among them being that the pad thus provided would become displaced with consequent discomfort to the wearer of the shoe, and again, if the insole is constructed of substantial leather, it will resist the pressure over the whole area and thus avoid special pressure in the region of the metatarsal arch. These difficulties are overcome in the present invention by providing a recess 8 which is out into the body of the last and in the sole portion 9 thereof. The recess referred to is adjacent the shank por tion 10 of the last, the rear walls 11 of the recess being substantially vertical and disposed coincident with the forward terminal end of the shank portion 10. The recess is preferably shaped as shown in thel drawings,

the forward edge 12 fading into the sole portion 9 of the last.

From the forward edge12 the recess rises or is deepened in the last back, to the rear walls 11. The recess thus formed is intended to house a raised or molded portion of a relatively thickened insole such as disclosed in an application for patent for improvement in shoe insole filed by me under date of April 22, 1924, having Serial No. 708,236, to which application, cross reference is here made, the thickened portion of the insole referred to being indicated in the drawings of the said application by means of the numeral 19. The wall 11 of the recess 8 in the present invention is shaped to correspond with the molded portion 19 of the application above referred to.

A shoe last thus constructed is used in the manufacture of shoes first receiving the insole, the molded portion of the insole fitting a recess 8 of the last. A shank iron having an upset forward extension corresponding to the molded portion of the insole and of the recess 8, is then placed upon the insole, the upset portion resting in the concave side of the molded portion of the insole. When the shoe is completed and the last is removed therefrom it is easil drawn back over the raised portion of t e insole, the inclined upper surface corresponding with the recess 8 affording ease with which the last may be drawn back. It' will now be found that the shoe is provided with a substantially lifted or elevated area which registers with the foot of the wearer and under the metatarsal arch thereof to support the same in service.

The present disclosure differentiates from the disclosure shown in a Patent No. 1,237,- 464: granted to me August 21, 1917, for improvements in lasts in that the recess 8 is deepest at what may be termed the rear of the wearing sole of the shoe, whereas in the former disclosure the recess was deepest at the forward edge thereof or what may be termed within the wearing sole of the shoe,

In the former disclosure, the recess was intended to receive a pad that was supported by a forward extension of theshank iron of the shoe and the thickest dimension of the pad was coincident with the forward edge of the recess. In the present disclosure the recess 8 is designed to receive the upset portion of the molded insole which supplements or replaces the pad above referred to as provided for in the older construction and at the vshank portion thereof, the deepest porthe same time afl'ords registering member tion of said cavity being adjacent the partfor locating the insole on the last during ing line of said sole and shank portion of the process of manufacturing shoes. the last, the lines of the rear Walls of said 5 I claim:
