Abstract
An article of footwear includes a sole structure effective to increase traction on a support surface and including first and second sets of lugs. The first lugs can bend or move so as to decrease in dimension a greater amount in comparison to the second lugs in response to a force being applied to each of the first lugs and the second lugs.
Claims13
An article of footwear comprising:
- a sole structure to engage a ground surface, the sole structure comprising:
- a first portion including a first top surface, a first bottom surface, and a plurality of first lugs, each first lug extending from the first bottom surface of the first portion to a first free end, wherein a first distance is defined between the first bottom surface of the first portion and the first free end of each first lug;
- a second portion including a second top surface, a second bottom surface, and a plurality of second lugs, each second lug extending from the second bottom surface of the second portion to a second free end, wherein a second distance is defined between the first bottom surface of the first portion to the second free end of each second lug;
- wherein:
- the first distance is greater than the second distance;
- each first lug has a first durometer, each second lug has a second durometer, and the second durometer is greater than the first durometer;
- and
- each first lug is compressible during use of the article of footwear, in which a wearer of the article of footwear engages the ground surface with the sole structure, such that each first lug compresses to decrease the first distance to a third distance defined between the first bottom surface of the first portion to the first free end of each first lug.

- wherein each first lug has a first durometer, each second lug has a second durometer,
- and the second durometer is greater than the first durometer;
- and in response to a force being applied to each of the first lugs and the second lugs:
- each first lug bends or moves so as to decrease in a length dimension from the first distance to a third distance defined between the first bottom surface of the first portion to the first free end of each first lug;
- and
- each first lug widens in dimension at the first free end of each first lug.
