## Abstract

The present invention is intended for use in the high/superhigh-heel shoes. The suggested high-heel shoe comprises a support surface for a wearer's foot comprising a toe portion for receiving a toe portions of the wearer's foot, a forefoot portion for receiving a metatarsal area of the wearer's foot, a midfoot portion corresponding to location of midfoot area of the wearer's foot, and a heel portion for receiving a heel area of the wearer's foot. The forefoot portion of the support surface in zone of its transfer to the midfoot portion comprises two areas located at different distances relative to the support surface plane: a little toe metatarsophalangeal articulation zone supporting area and a big toe metatarsophalangeal articulation zone supporting area. A distance of the little toe metatarsophalangeal articulation zone supporting area to the support surface plane is at least 5 mm larger than a distance of the big toe metatarsophalangeal articulation zone supporting area to the support surface plane. Besides, a surface of the little toe metatarsophalangeal articulation zone supporting area surface is shaped in such a way that at least in one point of it the tangent to the line formed by its intersection with the plane (II) parallel to the plane (I) perpendicular to the support surface plane and passing through the most remote from each other points of the heel portion and the toe portion of the shoe is inclined relative to the support surface plane to an angle not more than 10° in absolute magnitude. Moreover, a tangent in the heel portion to the midfoot portion area transition zone to the line formed by intersection of the support surface with the plane (I) perpendicular to the support surface plane and passing through the most remote from each other points of the heel portion and the toe portion of the shoe is inclined relative to the support surface plane to the angle not exceeding 15 The shape of the foot bearing surface of the suggested shoe improves wearing comfort of the high/superhigh-heel shoes.

## Claims

### Claim 1

A high-heel shoe comprising a support surface for a user's foot comprising:
a toe portion for receiving a toe portion of a wearer's foot; a forefoot portion for receiving a metatarsal area of the wearer's foot;
a midfoot portion corresponding to location of a midfoot area of the wearer's foot; and
a heel portion for receiving a heel area of the wearer's foot, wherein the forefoot portion of the support surface in zone of its transfer to the midfoot portion comprises two areas located at different distances relative to the support surface plane: a little toe metatarsophalangeal articulation zone supporting area and a big toe metatarsophalangeal articulation zone supporting area, wherein a distance of the little toe metatarsophalangeal articulation zone supporting area to the support surface plane is at least 5 mm larger than a distance of the big toe metatarsophalangeal articulation zone supporting area to the support surface plane, and a surface of the little toe metatarsophalangeal articulation zone supporting area is shaped in such a way that at least in one point of it the tangent to the line formed by its intersection with the plane parallel to the plane perpendicular to the support plane and passing through the most remote from each other points of the heel portion and the toe portion of the shoe is inclined relative to the support surface plane to an angle of not more than 10° in absolute magnitude.

### Claim 2 (depends on 1)

The shoe according to claim 1, wherein a tangent in the heel portion to midfoot portion area transition zone to the line formed by intersection of the support surface with the plane perpendicular to the support surface plane and passing through the most remote from each other points of the heel portion and the toe portion of the shoe is inclined relative to the support surface to the angle not exceeding 15°.
