strength to support the weight of the body,`

the bones ofthe foot assume a permanent relocation and a condition known as flat foot results. In the usualV model ofshoe,

there is provided a built in arch varying ine form and height with the particular model,

which while partially supportingthc arches, still permits free exercise of the foot muscles.

When the condition of flat foot exists,-

this type of shoe cannot be worn withcomfort,

and special foot wear is necessary for the par! v ticular case, orlin lieu, a shoe with ilexible arch,- or one without arch is necessary. My-

arch` supporter :is'adapted -to function with both fallen arches and permanent flat foot conditions, in the one case operating as a'cor- `rective means for restoration Vof Vthe arclito "normal, and in the other Aserving to give suiii-V cient support to the foot to enable one to wear a shoe with the usual form of yarch without bringing undue pressure to bear at any point n and with vminimum restriction of the circuiation. `As the height of the normal arch of the foot differs according to'tlie'individual, `my

invention may be used with a shoe having an ordinary height of arch, to enable one with a normally low arch foot, to wear such a shoe My invention comprises a'fienible` baselextending longitudinally when iii position in the shoe.v Y In this is formed oneV or more trans-- verse passages in which may beinse'rted adjustmentV lifts,` adapted to uextend .there-V through and varying inthiclness at different cross sections, to coact with Vthe flexible `baseto build up the arch `supporter to function within the scope of the foregoing cases.

In the accompanying specifications and claim, and the drawings forming a part the-reof, have described and illustrated my invention. y

In the drawings, Fig. l represents a human mal arch.

VFig.V 11 is a similar view of a lift Lsuch as would be-used for compensating purposes.

In the drawings I have shown a preferred form of my invention in which I use a pair of' iieXible'base'v'elementg 20-21 stitched at -22-23`to form a lateral passage therebetween, open at both ends, and converging toward the side corresponding with the outer longitudinal arch of the foot.

Thestitching is continued around the heel and toe portions of the base, and the upper element 2lof the base isl formed tooverlap the lower element 20. In a shoe as usually" constructed, the junction of the upper with the innervsole forms a seam as at 24, Fig. 5,

resulting often in the formation of callouses on the sole of the foot where it overlaps the inner sole. The additional thickness of 'the arch supporter base as it is usually made, aggravates this tendency, but in my invention the overlapping upper element overlaps and bridges this seam and cushions the sole of the foot where it would otherwise mould along theseam and from the callous.

l/Vhile I prefer the form of base formed from two elements, it may also be formed of,V

a single element to include the passage -described. In either case the overlapping porton 21 is embodied, and may be skived to Vapproximately an edgef where it engages the upper of the shoe. In Fig. 5 I have indicated this condition, 2fi"`rep`resenting the innersoleV Yand 24 the contiguous portion of the upper. The passage described is adapted to receive lifts 25 ofthe required: forni and in suiiicient' number for the purpose for which the arch supporter is to be used. The longitudinal limits of the passage approximate therlines of the transverse and anterior metatarsal arches respectively as at 26-27, and inthe'wedge shaped passage thus formed, the insertable lifts 25, of corresponding outmay be introduced. These lifts vary in thiclness, diminishing on the median line 28 from the widest part 29 of the wedge toward the narrowest, 30. Transversely the lifts are varied in thickness according as they arel to be used as a corrective means for fallen arches, or to form a compensating means Vwhen a high arch shoe is worn with a normally low arched foot. In addition, the thickness of the lifts may be variedfor the purpose of furnishing'suppo-rt for Weak ankle muscles and thus prevent unequal wear on the sides of the heel.

` In the first case, the lift is formed in section as inv Fig.rl0, with a lateral section taper,- ing in thickness toward the

edges

31,32. In the second case the liftisbeveled from a ice relatively thick section near the lateral limits to a thin section at the median line. For

the support of weak anklemuscles, thek lon itudinal and the lateral thickness ofthe li `would necessarily depend on the degree of` correction required. F or cases of flat foot, I prefery to use a modication of my arch supporter,'in which I 'f form two passages `:by

means of an extra line of stitching, 33, on or near the'lateral median line of the base. L

In this form I enlarge the extreme longitudinal limits of the passages' to provide space to insert lifts in each passage to secure the results shown in Fig. 6. The form of lift shown in Fig. 11 may however be used in connection with an arch supporter having a single ypassage for use with a medium arched shoe and an ordinary case of flat foot. In each case the lifts extend laterally of the base and support both longitudinal arches, as well as the transverse ,v and ,interior metatarsal arches, the beveled sectionsof thelifts c'oacting with the walls; of the passage to conform both with the sole of the footand with the arch of .the shoe worn. While the size and form of the arch supporter base and the Y corresponding lifts may be varied according u to the particular foot and shoe, my invention is susceptible of standardization for vuse'with different models and sizes of. shoey andv for different conditions of 'the footV within the Scope ofk this specicationf In Figs. 1 and 2 they-0S calais is yii1 iiaa i at a and the sesamoid at b showing the limits .ofV the inner longitudinalarch;` the arch of the average shoe is indicated at c Fig. l and the corresponding portion 'as applicable toa flat foot is indicated at d Fi 2.4 *Inf Fig. 3 the relative positions of the our component arches areindicated, Afshowing diagrammatically the inner longitudinal and B.` the outer longitudinal arches, C showing the transverse arch and D the anterior metatar-V sal arches, all merging as explained to form the compound arch .of the foot.

VHaving thus described vmy invention kI1 claim Y In an arch supporter of the character described, in combination with a flexible member having a lateral passage extending therethrough, filling lifts tapered in theirlength,

each having'a truncated wedge section on itsM median line and laterally tapered therefrom, and adaptable to be inserted in and through the passage formed inthe flexible member and c adjustable to support both longitudinal?, arches, and to coact with'the walls of the passage in the flexible member, to conform with, and to support bothgthe transverse' and P y the anterior metatarsal arches.
