Abstract
A laced shoe construction providing improved means for adjusting the effective girth of a shoe to the foot therein, particularly along lower side edges thereof.
Description
GIRTHWISE ADJUSTABLE LACED SHOE CONSTRUCTION
BACKGROUND OF THE INVENTION
This invention comprises a shoe construction providing improved means for adjusting the effective girthwise fit of a shoe to that of a foot therein, including at both upper and lower side portions adjacent to at least one of the ball, waist, and instep areas of the foot.
It is well-known that for a comfortable fit, a shoe should not only be of suitable length but also be of suitable girth to provide a comfortably close fit to the foot of the wearer. In the past, this had been approached by custom-made shoes, and by factory-made shoes being offered in multiple so-called widths (i.e.
girths).
However, neither approach provided proper girth adjustment along the lower sides of the foot to be able to match the usual diurnal foot girth variations of up to 2 full widths due to the normal accumulation of body fluids in the extremities over each day. This invention provides such adjustment while holding the foot securely trans-versely centered in the shoe at all such adjustments. This is a feature that has long been especially needed in athletic and other active shoe footwear.
This invention further provides the low store inventories of conventional single width shoe approaches, but with means to adjust these shoes over a multiple successive girth range to properly fit most wearers, including over typical diurnal foot girth ranges.
As for relevant prior art, none seems to have been able to fully satisfy the foregoing criteria. Such prior art includes, but is not limited to the following U.S.
Patent Numbers: 2,691,227; 3,404,468; 3,442,031; 3,541,708; 3,618,235;

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawings, a typical so-called athletic shoe style is shown, in a construction embodying principles of the present invention, applicable to other similarly adjusted shoe designs as well.
In the present invention, full girthwise adjustment of a shoe, preferably span-ning at least four standard successively adjacent widths (or `girths'), is provided by the manual lacing adjustment of a relatively inelastically flexible, preferably woven fabric loose lining element attached to the topline of the outer vamp element of the upper assembly, rather than by the vamp element alone, as in the conventional lacing adjustment of similar shoe styles.
More particularly, the present invention is directed to a manually operable girthwise adjustable shoe construction, including (i) a shoe upper assembly having an outer component and an inner component, (ii) a shoe bottom assembly having a sole and insole, and (iii) manually, operable means to adjust the effective girthwise dimensions of the inner components of the shoe, said inner components of the upper assembly comprising a loose lining means located inwardly adjacent to the laced portions of the upper assembly. The loose lining is attached, as by stitching means, to both the topline of the outer vamp of the shoe 20, and to a fixed insole, optionally of similar fabric, along a line corresponding to that of the perimeter of the bottom of a shoe last having the least girth of the particular girthwise adjust-ment range for which the shoe is designed. This provides a closely comfortable girthwise fit of both the upper and lower laced side portions of the shoe 20 to a foot therewithin.
FIG. 1 shows a shoe 20, comprising an upper assembly 22, including a vamp 24, and a relatively inelastic flexible loose fabric lining 26, attached to the topline 28 of the vamp 24 as by stitching 30. Upper assembly 22 also includes a combined tongue and forepart element 32, with said upper assembly 22 having a fixed insole 42 attached to the lower perimeter of the vamp 24 as by butt-stitching 46.
Both vamp 24 and fixed insole 42 are attached to a molded rubber or similar polymeric unitsole 40, as by a conventional direct molding process. FIG. 1 also shows a conventional shoelace 34, laced through the eyelets 36 attaching vamp 24 to loose lining 26. The rearmost free ends of shoelace 34 are adjustably attached by a usual bow-knot (not shown), or by equivalent means. FIG. 1 also shows a trim stitching 38 on the vamp 24 optionally stitched to the lining 26 thereunder.
FIGS. 2 and 3 show transverse elevations of the shoe 20 along the lines 2-2 and 3-3 thereof. FIG. 2-2 shows the shoe 20 adjusted to a greater girth, while FIG.
3-3 shows its adjustment to a lesser girth. Both figures show the shoe elements disclosed above including upper assembly 22, vamp tongue and forepart 32, and loose vamp lining 26, optionally of one piece as shown, and attached as by stitching 44 to the fixed insole 42 thereunder. The fixed insole 42 is preferably of the same or similar material to that of the loose lining 26 and the stitching 44 is located along a line on fixed insole 42 corre-sponding to the lower peripheral edge (i.e.
"last bottom") of a shoe last of the least girth fitting the particular girth adjustment range of the shoe 2. The fixed insole 42 has a width dimension along the bottom periphery of a shoe last of the maximum girth of the particular girth adjustment range for which the shoe 20 has been designed. The fixed insole 42 is preferably of the same or similar inelastic flexible woven fabric as that used to form the loose lining 26, and is conventionally attached to the lower periphery of the vamp 24 and forepart 32 as by butt-stitching means 46, both being attached to the unitsole thereunder by direct sole-molding means.
It will be noted that manually operable shoe girth adjustment means equiva-lent to the preferred lacing means disclosed above will include other conventional means such as girth adjustable straps, buckles, hook and loop closures, and like means.
The shoe construction of the present invention is designed to provide an infinitely variable manually operable shoe girth adjustment within its designed girth ranges. Generally this will provide an appropriate girthwise fit to most of the wearers of each length size thereof.
Optionally the shoe may be designed to cover multiple separate girth ranges, if desired. For example, one shoe can be designed for a men's girth range of B-C-D-E, while a second similar design can be designed for a range of greater girths, as D, E, EE and EEE. The specific girth ranges are open to the preferences of the shoe manufactur-er. The specific girth ranges can differ according to the size ranges applicable and the specific customer category, i.e. men, women, or children.
As for materials and sources, uppers may include leather from Prime Tanning, Inc., of Berwick, ME and others. Simulated leather and other fabrics and materials can be supplied by Geo. C. Moore, Inc., of Westerly, RI and others.
Shoe laces will be from Textile Tapes, Inc., of Gonic, NH. Eyelets, washers and similar fastenings will be supplied by Trendware/Goldberg Footwear Components, Inc.,.
of Salem, MA.
It should be understood that the present invention is readily applicable to a wide range of shoe designs, including those with other girth adjustment means considered equivalent to the preferred lacing means shown in the figures and disclosures herewith and including adjustable straps, hook and loop closures, buckles, and like means.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawings, a typical so-called athletic shoe style is shown, in a construction embodying principles of the present invention, applicable to other similarly adjusted shoe designs as well.
In the present invention, full girthwise adjustment of a shoe, preferably span-ning at least four standard successively adjacent widths (or `girths'), is provided by the manual lacing adjustment of a relatively inelastically flexible, preferably woven fabric loose lining element attached to the topline of the outer vamp element of the upper assembly, rather than by the vamp element alone, as in the conventional lacing adjustment of similar shoe styles.
More particularly, the present invention is directed to a manually operable girthwise adjustable shoe construction, including (i) a shoe upper assembly having an outer component and an inner component, (ii) a shoe bottom assembly having a sole and insole, and (iii) manually, operable means to adjust the effective girthwise dimensions of the inner components of the shoe, said inner components of the upper assembly comprising a loose lining means located inwardly adjacent to the laced portions of the upper assembly. The loose lining is attached, as by stitching means, to both the topline of the outer vamp of the shoe 20, and to a fixed insole, optionally of similar fabric, along a line corresponding to that of the perimeter of the bottom of a shoe last having the least girth of the particular girthwise adjust-ment range for which the shoe is designed. This provides a closely comfortable girthwise fit of both the upper and lower laced side portions of the shoe 20 to a foot therewithin.
FIG. 1 shows a shoe 20, comprising an upper assembly 22, including a vamp 24, and a relatively inelastic flexible loose fabric lining 26, attached to the topline 28 of the vamp 24 as by stitching 30. Upper assembly 22 also includes a combined tongue and forepart element 32, with said upper assembly 22 having a fixed insole 42 attached to the lower perimeter of the vamp 24 as by butt-stitching 46.
Both vamp 24 and fixed insole 42 are attached to a molded rubber or similar polymeric unitsole 40, as by a conventional direct molding process. FIG. 1 also shows a conventional shoelace 34, laced through the eyelets 36 attaching vamp 24 to loose lining 26. The rearmost free ends of shoelace 34 are adjustably attached by a usual bow-knot (not shown), or by equivalent means. FIG. 1 also shows a trim stitching 38 on the vamp 24 optionally stitched to the lining 26 thereunder.
FIGS. 2 and 3 show transverse elevations of the shoe 20 along the lines 2-2 and 3-3 thereof. FIG. 2-2 shows the shoe 20 adjusted to a greater girth, while FIG.
3-3 shows its adjustment to a lesser girth. Both figures show the shoe elements disclosed above including upper assembly 22, vamp tongue and forepart 32, and loose vamp lining 26, optionally of one piece as shown, and attached as by stitching 44 to the fixed insole 42 thereunder. The fixed insole 42 is preferably of the same or similar material to that of the loose lining 26 and the stitching 44 is located along a line on fixed insole 42 corre-sponding to the lower peripheral edge (i.e.
"last bottom") of a shoe last of the least girth fitting the particular girth adjustment range of the shoe 2. The fixed insole 42 has a width dimension along the bottom periphery of a shoe last of the maximum girth of the particular girth adjustment range for which the shoe 20 has been designed. The fixed insole 42 is preferably of the same or similar inelastic flexible woven fabric as that used to form the loose lining 26, and is conventionally attached to the lower periphery of the vamp 24 and forepart 32 as by butt-stitching means 46, both being attached to the unitsole thereunder by direct sole-molding means.
It will be noted that manually operable shoe girth adjustment means equiva-lent to the preferred lacing means disclosed above will include other conventional means such as girth adjustable straps, buckles, hook and loop closures, and like means.
The shoe construction of the present invention is designed to provide an infinitely variable manually operable shoe girth adjustment within its designed girth ranges. Generally this will provide an appropriate girthwise fit to most of the wearers of each length size thereof.
Optionally the shoe may be designed to cover multiple separate girth ranges, if desired. For example, one shoe can be designed for a men's girth range of B-C-D-E, while a second similar design can be designed for a range of greater girths, as D, E, EE and EEE. The specific girth ranges are open to the preferences of the shoe manufactur-er. The specific girth ranges can differ according to the size ranges applicable and the specific customer category, i.e. men, women, or children.
