FOOTWEAR COMPRISING A DYNAMIC MATERIAL EXHIBITING TOPOGRAPHIC TRANSFORMATION
An upper of an article of footwear including a dynamic material configured for topographic transformation to alter at least one of a fit, an insulation, or a ventilation, of the article of footwear.
1 . An article of footwear comprising:
a sole structure, and
an upper coupled to the sole structure,
wherein the upper comprises a dynamic material,
wherein the dynamic material is configured to exhibit a topographic transformation along a first axis in response to a tension or torgue being applied to the dynamic material along a second axis orthogonal to the first axis, and
wherein the topographic transformation alters at least one of a fit, an insulation, or a ventilation, of the article of footwear.
2 . The article of footwear of claim 1 , wherein the dynamic material comprises a plurality of layers coupled by a plurality of ribs, each of the plurality of ribs being configured to fold.
3 . The article of footwear of claim 2 , wherein the ribs are linearly aligned.
4 . The article of footwear of claim 2 , wherein the ribs are radially aligned.
5 . The article of footwear of claim 2 , wherein at least one of the layers comprises an aperture to provide the ventilation in connection with the topographic transformation.
6 . The article of footwear of claim 1 , wherein the dynamic material comprises a plurality of angled slits configured to expand along the first axis as an auxetic structure.
7 . An article of footwear comprising:
a sole structure, and
an upper coupled to the sole structure,
wherein the upper comprises a dynamic material,
wherein the dynamic material is configured to exhibit an increase in a thickness in response to an increase in length or width, and
wherein the increase in the thickness alters at least one of a fit, an insulation, or a ventilation, of the article of footwear.
8 . The article of footwear of claim 7 , wherein the dynamic material comprises a plurality of layers coupled by a plurality of ribs, each of the plurality of ribs being configured to fold.
9 . The article of footwear of claim 8 , wherein the ribs are linearly aligned.
10 . The article of footwear of claim 8 , wherein the ribs are radially aligned.
11 . The article of footwear of claim 8 , wherein at least one of the layers comprises an aperture to provide the ventilation in connection with the increase in the thickness.
12 . The article of footwear of claim 7 , wherein the dynamic material comprises a plurality of angled slits such that the dynamic material is configured to behave as an auxetic structure.
13 . A dynamic material for use in the upper of an article of footwear,
wherein the dynamic material is configured to exhibit a topographic transformation in a first plane in response to a tension or torque being applied to the dynamic material in a second plane out of the first plane, and
wherein the topographic transformation alters at least one of a fit, an insulation, or a ventilation, of the article of footwear.
14 . The dynamic material of claim 13 comprising a plurality of layers coupled by a plurality of ribs, each of the plurality of ribs being configured to fold.
15 . The dynamic material of claim 14 , wherein the ribs are linearly aligned.
16 . The dynamic material of claim 14 , wherein the ribs are radially aligned.
17 . The dynamic material of claim 14 , wherein at least one of the layers comprises an aperture to provide the ventilation in connection with the topographic transformation.
18 . The dynamic material of claim 13 , wherein the dynamic material comprises a plurality of angled slits configured to expand in the first plane as an auxetic structure.
