Abstract

An article of footwear is provided and includes an upper including a footbed, a midsole attached to the upper and including a heel portion, a lateral side and a medial side. An outsole is attached to the midsole to form a shell having a sidewall that extends along the medial side around the heel portion and along at least part of the lateral side, where the sidewall extends along the upper to a point above a top surface of the footbed. The extension of the sidewall above the footbed provides medial and lateral stability to a wearer's foot and also aligns the foot in the article of footwear.

First claim

What is claimed is:

1. An article of footwear comprising: an upper having a width and including a footbed; a midsole attached to the upper and including a heel portion, a lateral side and a medial side, said midsole including an upper surface and a lower surface, said upper surface extending across the width of the upper, wherein said footbed is on said upper surface of said midsole, said midsole forming a shell having a sidewall that extends along the medial side around the heel portion and along at least part of the lateral side, said sidewall extending along the upper to a point above a top surface of the footbed; and an outsole attached to the midsole; wherein a height of the sidewall on said lateral side is greater than a height of the sidewall on said medial side; wherein the difference of the hardness of said outsole and the hardness of said midsole is at least 10 Asker.

2. The article of footwear of claim 1 , wherein the hardness of the midsole is 45 Asker and the hardness of the outsole is 55 Asker.

3. The article of footwear of claim 1 , wherein said sidewall extends along a periphery of the medial side to a metatarsal head of a foot of wearer's when is worn.

4. A sole for an article of footwear having an upper and a footbed, the sole comprising:
a midsole attached to the upper and including an upper surface and a lower surface, said upper surface extending across a width of the upper, said midsole including a lateral side and a medial side, wherein the footbed is entirely on said upper surface of said midsole and positioned in an interior of the upper; and an outsole attached to the midsole, said midsole forming an integral shell having a sidewall that extends along a periphery of the upper from the medial side to at least part of the lateral side and above a top surface of the footbed, said shell having a longitudinal axis, wherein said sidewall is asymmetrical relative to said longitudinal axis;
wherein a height of the sidewall on said lateral side is greater than a height of the sidewall on said medial side or wherein a height of the sidewall on said medial side is greater than a height of the sidewall on said lateral side; wherein the difference of a hardness of said outsole and the hardness of said midsole is at least 10 Asker.

5. The sole of claim 4 , wherein the hardness of the midsole is 45 Asker an the hardness of the outsole is 55 Asker.

6. The sole of claim 4 , wherein said sidewall extends along the periphery from the medial side to a metatarsal head of a foot of wearer's when is worn.

7. An article of footwear comprising: an upper including an interior space and a footbed positioned within said interior space; and a sole including a midsole and an outsole, said sole being attached to the upper and including a heel portion, a lateral side and a medial side, said sole including an upper surface and a lower surface, said upper end extending across the width of said upper, wherein said footbed is on said upper surface of said sole, said sole forming a shell having a sidewall that extends along the medial side around the heel portion and along at least part of the lateral side, said sidewall extending along the upper to a point above the entire top surface of the footbed; wherein a height of the sidewall on said lateral side is greater than a height of the sidewall on said medial side; wherein the difference of the hardness of said outsole and the hardness of said midsole is at least 10 Asker.

8. The article of footwear of claim 7 , wherein the hardness of the midsole is 45 Asker and the hardness of the outsole is 55 Asker.

9. The article of footwear of claim 7 , wherein said sidewall extends along a periphery of the medial side to a metatarsal head of a foot of wearer's when is worn.
