Abstract
Footwear and its method of construction are provided. An insole forepart is attached to the bottom of the sock liner. An upper having a vamp lining with a toe part is provided where toe part is stitched to the sock liner such that the vamp lining and the sock liner together define a volume for receiving a wearer's foot. A steel toe is positioned substantially around the toe part of the vamp lining. An outsole having a forward portion formed of a material having a first resiliency characteristic is provided. A stiffener is positioned between the forward portion of the outsole and the insole forepart where the stiffener is formed of a material having a second resiliency characteristic less than the first resiliency characteristic.
Claims8
A method for construction of footwear comprising the steps of:
- attaching an insole forepart to the bottom of the sock liner;
- providing an upper having a vamp lining with a toe part, stitching toe part to the sock liner such that the vamp lining and the sock liner together define a volume for receiving a wearer's foot;
- positioning a steel toe substantially around the toe part of the vamp lining;
- providing an outsole having a forward portion formed of a material having a first resiliency characteristic;
- positioning a stiffener between the forward portion of the outsole and the insole forepart, the stiffener formed of a material having a second resiliency characteristic less than the first resiliency characteristic;
- placing a flange of the steel toe between the insole and the stiffener for supporting the steel toe;
- and
- opanka stitching at least the forward portion of the outsole to the upper.
A footwear construction comprising:
- a sock liner with an insole forepart attached to the bottom of the sock liner;
- an upper having a vamp lining with a toe part, stitching toe part to the sock liner such that the vamp lining and the sock liner together define a volume for receiving a wearer's foot;
- a steel toe positioned substantially around the toe part of the vamp lining;
- an outsole having a forward portion formed of a material having a first resiliency characteristic, the forward portion opanka-stitched to the upper;
- a stiffener between the forward portion of the outsole and the insole forepart, the stiffener formed of a material having a second resiliency characteristic less than the first resiliency characteristic;
- and
- said steel toe having a flange, said flange placed between said insole and said stiffener;
- wherein said stiffener further provides support to said steel toe.
The footwear construction wherein the stiffener has a plurality of ribs formed in a surface of the stiffener that is attached to the outsole.
A method for providing a shoe, comprising the steps of:
- providing an outsole having a forward portion;
- placing an insole above the forward portion;
- positioning a stiffener between the forward portion and the insole for providing rigidity to the shoe;
- placing a flange of a steel toe between the inside and the stiffener;
- wherein the stiffener further provides support to the steel toe;
- forming the stiffener such that a toe part does not readily bend in a downward direction with respect to a remaining portion of the shoe and to provide flexible support to allow the toe part to bend in an upward direction with respect to the remaining portion of the shoe;
- forming a plurality of ribs in a surface of the stiffener that contacts the outsole;
- forming the stiffener with a set of indentations along the surface of the stiffener that contacts the outsole.
