Abstract
A last having an outer footwear shaping surface is provided wherein the outer footwear shaping surface is constructed and arranged to have a foot length component corresponding to the length measurement of the foot, a width component corresponding to the width line, and curvature angles corresponding to the curvature angles of the foot. An arch-line component, a heel width component, and a foot volume component may also be provided to correspond with the foot.
Claims8
A last for manufacturing footwear for a measured foot, the last constructed and arranged to have an outer footwear shaping surface comprising:
- a) a length component;
- b) a width component;
- and
- c) a curvature angle component;
- wherein the length component, the width component, and the curvature angle component of the outer surface are derived from measurements of the measured foot;
- wherein the length component corresponds to a foot length line of the foot measured along a foot centerline extending between a heel point at the base of the heel and the middle of the tip of the second toe, the foot length line extending from the heel point to an intersection with a foot width line;
- wherein the width component corresponds to a foot width line of the foot measured along a line extending between the widest part of the foot at the first metatarsal head region and the widest part of the foot at the fifth metatarsal head region;
- and
- wherein the curvature angle component corresponds to:
- 1) a lateral curvature angle of the foot measured between the foot centerline and a line extending from the heel point to the widest part of the foot at the fifth metatarsal head region at the foot width line, and 2) a medial curvature angle of the foot measured between the foot centerline and a line extending from the heel point to the widest part of the foot at the first metatarsal head region at the foot width line.
A last for manufacturing footwear to fit feet which have a known combination of dimensions including a foot length measured along a foot centerline extending between a heel point at the base of the heel and the middle of the tip of the second toe, the foot length extending from the heel point to an intersection point with a foot width;
- a foot width measured along a line from the widest part of the foot at the first metatarsal head region to the widest part of the foot at the fifth metatarsal head region;
- a lateral curvature angle measured between the foot centerline and a line extending from the heel point to the widest part of the foot at the fifth metatarsal head region at the foot width;
- and a medial curvature angle measured between the foot centerline and a line extending from the heel point to the widest part of the foot at the first metatarsal head region at the foot width;
- the last having an outer footwear shaping surface constructed and arranged to have a combination of dimensions comprising:
- a) a length component corresponding to said foot length of the foot;
- b) a width component corresponding to said foot width of the foot;
- c) a lateral curvature angle component corresponding to said lateral curvature angle of the foot;
- and
- d) a medial curvature angle component corresponding to said medial curvature angle of the foot.
