Easy-to-wear functional shoe

1. An easy-to-wear functional shoe having a shoe heel and a sole, the functional shoe comprising:

a support member that supports the shoe heel; and

an elastic member that is coupled to an upper portion of the support member and protrudes inward from the functional shoe,

wherein the support member is substantially perpendicularly directly coupled to the sole at a lower end of the support member,

wherein an amount of a portion of the elastic member protruded from the support member gradually decreases toward side edges of the shoe heel in a plan view of the functional shoe,

wherein the support member has a semicircular arch shape surrounding the shoe heel,

wherein an entire region of the lower end of the support member is coupled to a slot provided in the sole,

wherein the elastic member includes:

a wearing surface that is inclined inward in a direction toward a lower side of the functional shoe; and

a seating surface that is inclined outward in a direction toward the lower side, and surrounds a foot heel,

wherein an upper end of the wearing surface contacts the support member,

a lower end of the wearing surface contacts an upper end of the seating surface, and

a lower end of the seating surface contacts the support member,

wherein the elastic member further includes a protective surface extending downward from both ends of left and right sides of the seating surface, and

wherein an angle formed between the wearing surface and a horizontal line, which is parallel to the ground and passes through a contact point of the wearing surface and the searing surface is smaller than an angle formed between the seating surface and the horizontal line.

2. The easy-to-wear functional shoe of claim 1 , wherein the support member is formed up to an upper end of the shoe heel.

3. The easy-to-wear functional shoe of claim 1 , wherein the elastic member is elastically deformed in a front-rear direction according to an external force caused by being in contact with a foot heel of a wearer.

4. The easy-to-wear functional shoe of claim 1 , wherein the elastic member is made of any one of rubber and urethane.

5. The easy-to-wear functional shoe of claim 1 , wherein the support member is made of a material having hardness sufficient to not allow the shoe heel to fold inward even by an external force applied by a wearer.

6. The easy-to-wear functional shoe of claim 1 , wherein the support member is made of a reinforced plastic material.

7. The easy-to-wear functional shoe of claim 1 , wherein an inclined section extending outward is formed at an upper end of the support member.

8. The easy-to-wear functional shoe of claim 1 , wherein the support member and the elastic member are provided between an inner skin and an outer skin of the shoe heel.

9. The easy-to-wear functional shoe of claim 1 , wherein the support member is made of carbon fiber.

10. The easy-to-wear functional shoe of claim 1 , wherein the support member is substantially a rectangular shape.

11. The easy-to-wear functional shoe of claim 1 , wherein the support member is substantially a rectangular shape with curved upper left and right corners.

12. An easy-to-wear functional shoe having a shoe heel and a sole, the functional shoe comprising:

a support member that supports the shoe heel; and

an elastic member that is coupled to an upper portion of the support member and protrudes inward from the functional shoe,

wherein the support member is substantially perpendicularly directly coupled to the sole at a lower end of the support member,

wherein an amount of a portion of the elastic member protruded from the support member gradually decreases toward side edges of the shoe heel in a plan view of the functional shoe,

wherein the support member has a semicircular arch shape surrounding the shoe heel,

wherein an entire region of the lower end of the support member is coupled to a slot provided in the sole, and

wherein an amount of a portion of the elastic member protruded from the support member at an upper end of the elastic member gradually decreases toward a lower end of the elastic member in a side view of the functional shoe.

13. An easy-to-wear functional shoe having a shoe heel and a sole, the functional shoe comprising:

a support member that supports the shoe heel; and

an elastic member that is coupled to an upper portion of the support member and protrudes inward from the functional shoe,

wherein the support member is substantially perpendicularly directly coupled to the sole at a lower end of the support member,

wherein an amount of a portion of the elastic member protruded from the support member gradually decreases toward side edges of the shoe heel in a plan view of the functional shoe,

wherein the support member has a semicircular arch shape surrounding the shoe heel,

wherein an entire region of the lower end of the support member is coupled to a slot provided in the sole,

wherein the elastic member includes:

a wearing surface that is inclined inward in a direction toward a lower side of the functional shoe; and

a seating surface that is inclined outward in a direction toward the lower side, and surrounds a foot heel,

wherein an upper end of the wearing surface contacts the support member,

a lower end of the wearing surface contacts an upper end of the seating surface, and

a lower end of the seating surface contacts the support member,

wherein the elastic member further includes a protective surface extending downward from both ends of left and right sides of the seating surface, and

wherein the wearing surface has a shape that is convex inward and concave outward.

14. The easy-to-wear functional shoe of claim 13 , wherein the support member comprises an inclined section at the upper portion of the support member, and

an outer surface of the wearing surface has a shape corresponding to an inner surface of the inclined section of the support member.
