Abstract
A shoe last and a method of using the shoe last to manufacture shoes that minimize the tendency of a wearer's foot to create increased pressure at the area of the ball of a wearer's foot are disclosed herein. The improved heel rest design relieves this pressure at the ball area of the foot by allowing the body weight to be more concentrated at the heel portion of the wearer's foot by redistributing the user's weight toward the heel portion and away from the ball of the foot.

A shoe last for forming a shoe, comprising:
- a body comprising a heel region including a surface and a sole surface, the sole surface comprising at least three distinct planar surfaces, the three distinct planar surface comprising:
- a toe box portion;
- a heel portion;
- and
- an arch support portion positioned between the toe box portion and the heel portion,
- wherein the heel region and the heel portion of the sole surface define a first angle therebetween, the surface of heel region and the arch support portion defining a second angle therebetween, the surface of the heel portion and the arch support portion defining a third angle therebetween, the second and the third angles being different, and wherein the heel portion of the sole surface has a concave shape.

A method of manufacturing a shoe, comprising:
- providing a shoe last, comprising:
- a body comprising a heel region including a surface and a sole surface, the sole surface comprising at least three distinct planar surfaces, the three distinct planar surface comprising:
- a toe box portion;
- a heel portion;
- and
- an arch support portion positioned between the toe box portion and the heel portion,
- wherein the heel region and the heel portion of the sole surface define a first angle therebetween, the surface of heel region and the arch support portion defining a second angle therebetween, the surface of the heel portion and the arch support portion defining a third angle therebetween, the second and the third angles being different, and wherein the heel portion of the sole surface has a concave shape;
- and
- forming a shoe by joining portions of the shoe around an exterior of the body of the shoe last,
- wherein the shoe includes a sole surface that is free from angled edges and includes a toe box portion, a heel portion, and an arch support portion, and wherein the heel portion defines a convex shape that corresponds to the concavity of the heel portion of the sole surface of the shoe last.
