Article of footwear having a polygon lug sole pattern
Articles of footwear, including athletic footwear, include one or more of: (a) an upper; (b) a sole structure including a midsole and an outsole, the outsole having a plurality of polygonal lugs arranged about a base surface of the outsole. The outsole may include one or more regions wherein the characteristics of a portion of the lugs within a region differ from the characteristics of a portion of the lugs in another region. The lugs may differ, for example based on size, construction and/or spacing between the lugs. Methods of manufacturing such articles of footwear also are disclosed.
1. An article of footwear, comprising:
an upper;
a midole connected to the upper; and
an outsole connected to the midsole, the outsole including:
a first region including a first plurality of polygonal lugs extending downward from a base surface and forming at least a portion of a ground contacting surface, the first region being arranged in a central portion of the outsole; and
a second region including a second plurality of polygonal lugs extending downward from the base surface and forming at least a portion of the ground contacting surface, the second region being arranged around a periphery of the central portion,
the first plurality of polygonal lugs having a hollow construction and a first wall thickness and the second plurality of polygonal lugs having a hollow construction and a second wall thickness different from the first wall thickness.
2. The article of footwear of claim 1 , wherein the plurality of lugs in the first region have a first spacing arrangement.
3. The article of footwear of claim 2 , wherein the plurality of lugs in the second region have a second spacing arrangement different from the first spacing arrangement.
4. The article of footwear of claim 3 , wherein the first spacing arrangement includes more closely positioned lugs than the second spacing arrangement.
5. The article of footwear of claim 4 , wherein at least a portion of the plurality of lugs in the first region are spaced at least 1 mm apart.
6. The article of footwear of claim 4 , wherein at least a portion of the plurality of lugs in the second region are spaced at least 1.5 mm apart.
7. The article of footwear of claim 1 , wherein at least one of the plurality of lugs of the first region has a size different from at least one of the plurality of lugs in the second region.
8. The article of footwear of claim 7 , wherein at least one of the lugs of the first region is larger than at least one of the lugs of the second region.
9. The article of footwear of claim 7 , wherein the plurality of lugs in the first region are between 2 mm and 7 mm wide.
10. The article of footwear of claim 7 , wherein the plurality of lugs in the second region are between 1 mm and 5 mm wide.
11. The article of footwear of claim 1 , wherein the first wall thickness is greater than the second wall thickness.
12. The article of footwear of claim 1 , wherein the first wall thickness is between 3 mm and 20 millimeters.
13. The article of footwear of claim 1 , wherein the second wall thickness is between 1 mm and 5 millimeters.
14. The article of footwear of claim 1 , wherein distal ends of the plurality of lugs in the first region opposite the base surface are not in contact with each other.
15. The article of footwear of claim 14 , wherein the distal ends of the plurality of lugs in the second region opposite the base surface are not in contact with each other.
16. The article of footwear of claim 1 , wherein the plurality of lugs in the first and second region have a uniform shape.
17. The article of footwear of claim 1 , wherein at least some of the plurality of lugs in the first and second regions are hexagonal.
18. The article of footwear of claim 1 , further including a third region including a plurality of polygonal lugs extending downward from the base surface and forming at least a portion of the ground contacting surface, the third region being arranged in a toe region of the article of footwear.
19. The article of footwear of claim 18 , wherein at least a portion of the plurality of lugs of the third region are substantially similar in size to at least a portion of the plurality of lugs of the first region.
20. The article of footwear of claim 18 , wherein at least a portion of the plurality of lugs of the third region are substantially similar in size to at least a portion of the plurality of lugs of the second region.
21. The article of footwear of claim 18 , wherein the plurality of lugs in the third region have a third spacing arrangement.
