Abstract
Abstract The specification describes a shoe, particularly of the moccasin type, having a sole body which is shaped, as viewed from above, substantially to conform to the shape of the foot so that it has a so-called "natural" shape. The sole of the shoe is lasted so that the upper surface has zero arching and located under the front portion and under the heel portion are downwardly extending projections, the two projections extending downwardly the same height from the upper surface so that, in use, the upper surface is parallel to the ground on which the shoe is placed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
166 words
A shoe comprising an upper and a sole, the sole including a sole body having upper and lower surfaces, the shape of the sole body, as viewed from above, being approximately that of the foot of a wearer, a front portion, an arch portion and a heel portion of the sole, two downwardly extending projections extending across the width of the lower surface of said sole body, the projections being produced by variations in the thickness of the sole body, the first of said projections being located under the heel portion of the sole body adjacent the arch portion and the second of said projections being located under the front portion at the location of the ball of the foot of the wearer, the projections being of substantially equal height from said upper surface, the upper surface of the sole body in the arch and heel portions being curveless in the longitudinal direction and having a longitudinal axis in said portions extending in a horizontal plane.
Claim 2
Dependent Claim
166 words
A shoe comprising an upper and a sole, the sole including a sole body having upper and lower surfaces, the shape of the sole body, as viewed from above, being approximately that of the foot of a wearer, a front portion, an arch portion and a heel portion of the sole, two downwardly extending projections extending across the width of the lower surface of said sole body, the projections being produced by variations in the thickness of the sole body, the first of said projections being located under the heel portion of the sole body adjacent the arch portion and the second of said projections being located under the front portion at the location of the ball of the foot of the wearer, the projections being of substantially equal height from said upper surface, the upper surface of the sole body in the arch and heel portions being curveless in the longitudinal direction and having a longitudinal axis in said portions extending in a horizontal plane.
Claim 3
Dependent Claim
14 words
A shoe according to claim 1, wherein the projections are of curved dome-shaped configuration.
Claim 4
Dependent Claim
22 words
A shoe according to claim 2, wherein the angle subtended by said curved portions of said projections is between 150° and 160°.
Claim 5
Dependent Claim
28 words
A shoe according to claim 1, wherein the underside of the heel and the outsole front portion blend in a continuous line on either side of said projections.
Claim 6
Dependent Claim
49 words
A shoe according to claim 1, wherein the sides of the projections facing towards one another and towards the arch portion extend at a steeper angle to the upper surface than the sides which face away from one another towards the front part and heel part of the shoe.
Claim 7
Dependent Claim
20 words
A shoe according to claim 1, wherein the sole and heel portions of the upper are moulded onto the sole.
Claim 8
Dependent Claim
159 words
A shoe sole comprising a sole body having upper and lower surfaces, the shape of the sole body, as viewed from above, being approximately that of the foot of a wearer, a front portion, an ankle portion and a heel portion of the sole, two downwardly extending projections extending across the width of the lower surface of said sole body, the projections being produced by variations in the thickness of the sole body, the first of said projections being located under the heel portion of the sole body adjacent the ankle portion and the second of said projections being located under the front portion at the location of the ball of the foot of the wearer, the projections being of substantially equal height from said upper surface, the upper surface of the sole body in the ankle and heel portions being curveless in the longitudinal direction and having a longitudinal axis in said portions extending in a horizontal plane.
Claim 9
Dependent Claim
159 words
A shoe sole comprising a sole body having upper and lower surfaces, the shape of the sole body, as viewed from above, being approximately that of the foot of a wearer, a front portion, an ankle portion and a heel portion of the sole, two downwardly extending projections extending across the width of the lower surface of said sole body, the projections being produced by variations in the thickness of the sole body, the first of said projections being located under the heel portion of the sole body adjacent the ankle portion and the second of said projections being located under the front portion at the location of the ball of the foot of the wearer, the projections being of substantially equal height from said upper surface, the upper surface of the sole body in the ankle and heel portions being curveless in the longitudinal direction and having a longitudinal axis in said portions extending in a horizontal plane.
Claim 10
Dependent Claim
116 words
A shoe sole according to claim 7 wherein the lower surface of the sole body from the projection located under the heel extends in a substantially continuous line to the back of the heel portion, reducing the thickness thereof at the back of the heel, and the lower surface of the sole body from the projection located under the ball of the foot extends in a substantially continuous line to the toe of the sole reducing the thickness thereof at the toe end, and there is formed between the two projections an arch portion wherein the thickness of the sole is reduced along the entire extent thereof, giving the sole the appearance of having a heel.
Claim 11
Dependent Claim
115 words
A shoe according to claim 1, wherein the lower surface of the sole body from the projection located under the heel extends in a substantially continuous line to the back of the heel portion, reducing the thickness thereof at the back of the heel, and the lower surface of the sole body from the projection located under the ball of the foot extends in a substantially continuous line to the toe of the sole reducing the thickness thereof at the toe end, and there is formed between the two projections an arch portion wherein the thickness of the sole is reduced along the entire extent thereof, giving the sole the appearance of having a heel.
