Abstract
The invention is an article of footwear having a sole comprised of one or more support elements formed of a resilient, compressible material. The support elements are designed such that the positions of one or more bands that encircle the exterior surface of the support elements may be altered such that the deflection characteristics of the support elements are changed. In order to facilitate the repositioning of the bands, the support element includes an access indentation defined by the exterior surface or flanges that are secured to each band.
Claims5
A method for modifying properties of a sole of an article of footwear, the method comprising steps of:
- positioning a band in a first location with respect to an exterior surface of a support element of the sole to provide the support element with a first stiffness, the band having a configuration that extends around the support element;
- and
- repositioning the band to a second location with respect to the exterior surface to provide the support element with a second stiffness,
- wherein the steps of positioning and repositioning include grasping a flange that extends outward from the band.
A method for modifying properties of a sole of an article of footwear, the method comprising steps of:
- positioning a first band and a second band with respect to an exterior surface of a support element of the sole to provide the support element with a first stiffness, the first band and the second band having a configuration that extends around the support element;
- and
- repositioning the first band and the second band with respect to the exterior surface to provide the support element with a second stiffness,
- wherein the steps of positioning and repositioning include utilizing an access indentation formed in the exterior surface to facilitate movement of the first band and the second band.
A method for modifying properties of a sole of an article of footwear, the method comprising steps of:
- positioning a first band with respect to an exterior surface of a first support element of the sole to select a stiffness for the first support element, the first band having a configuration that extends around the first support element;
- positioning a second band with respect to an exterior surface of a second support element of the sole to select a stiffness for the second support element, the second band having a configuration that extends around the second support element;
- positioning a third band with respect to an exterior surface of a third support element of the sole to select a stiffness for the third support element, the third band having a configuration that extends around the third support element;
- positioning a fourth band with respect to an exterior surface of a fourth support element of the sole to select a stiffness for the fourth support element, the fourth band having a configuration that extends around the fourth support element;
- and
- repositioning at least one of the first band, the second band, the third band, and the fourth band to modify a stiffness of the sole,
- wherein the steps of positioning and repositioning include grasping flanges that extends outward from the bands.
