Abstract
A shoe insole includes a semi-rigid shell for providing a wearer with extended comfort. The semi-rigid shell includes a notch which is located on the outward side of the wearer's foot and accommodates pronation of the foot during use. Additionally, the semi-rigid shell includes an extended side portion which is located opposite of the notch side on an inner side of the wearer's foot. The semi-rigid shell is shorter in length than the length of a shoe sole and slightly shorter in width and may be combined with an insole comfort cover to provide cushion between the wearer's foot and the semi-rigid shell.

A semi-rigid shell for a shoe insole, comprising:
- a unitary composition of semi-rigid material having a length that is less than a total length of the shoe insole;
- wherein the unitary composition includes a first extended side that extends at least 30 mm up an inner side of a wearer's foot at a highest point in a direction perpendicular to the shoe insole at a first edge and slopes down on either side of the highest point, said first extended side is opposite of a second non-extended edge;
- and
- further wherein, along a second edge of the second non-extended side opposite the first edge on an outside of a wearer's foot, the unitary composition includes a notch that extends into the width of the second non-extended edge by at least approximately 10 mm.
A tri-layer shoe insole comprising:
- a first layer formed of a semi-rigid material and having a first length and first width that are less than a tri-layer shoe sole length and width, wherein the first layer includes a first extended side that extends at least 30 mm up the inner side of a wearer's foot at a highest point in a direction perpendicular to the tri-layer shoe insole at a first edge and slopes down on either side of the highest point, said first extended side is opposite of a second non-extended edge;
- the first layer further including a notch located along a second edge of the second non-extended side opposite the first edge, wherein the notch extends into a width of the second non-extended edge by at least approximately 10 mm;
- a second layer contacted to the first layer, the second layer being formed of a flexible material and having a second length and a second width that are approximately equal to the tri-layer shoe insole length and width;
- and
- a third layer contacted to the second layer, the third layer being formed of a wicking material and having a third length and a third width that are approximately equal to the shoe insole length and width.
A shoe support insole, comprising:
- a semi-rigid shell of unitary composition of semi-rigid material;
- and
- a shell cover, wherein the shell cover is approximately equal in length and width to a length and width of a shoe's insole and the semi-rigid shell's dimensions are less than the length of the shell cover and less than the width of the shell cover;
- wherein the unitary composition includes a first extended side that extends at least 30 mm up the inner side of a wearer's foot at a highest point in a direction perpendicular to the shoe insole at a first edge and slopes down on either side of the highest point, said first extended side is opposite of a second non-extended edge;
- and
- further wherein, along a second edge of the second non-extended side opposite the first edge, the unitary composition includes a notch that extends into the width of the second non-extended edge by at least approximately 10 mm.
