Benefits of technology

[0009]In another embodiment, an internal shank for an article of footwear may include a base having a heel portion and a toe portion, the base adapted to be molded within a sole of the article of footwear. A first cut is disposed through the toe portion of the base and extends along a first axis, the first cut separating a first platform and a second platform of the base. A second cut is disposed through the toe portion of the base adjacent to the first cut and extends along a second axis, the second cut separating a third platform of the base from the second platform of the base. A third cut is disposed through the toe portion of the base adjacent to the second cut and extends along a third axis, the third cut separating a fourth platform of the base from the...

Problems solved by technology

Designing footwear to balance both athleticism and wearability has proven a source of difficulty when utilizing conventional footwear design characteristics.
As the athleticism of a shoe or sport sandal increases, the wearability or comfort level of such apparel often can diminish.
Any slippage or movement of the foot within the shoe results in a loss of athleticism for the user since the footwear is not optimally transmitting the forces from the user's foot to the ground below.
Unfortunately, such a tightly secured fitment can be both uncomfortable and unhealthy for the user over extended time periods due to the constriction of their foot.
Unfortunately, footwear with toe pockets have several undesirable consequences.
Indeed, the footwear acts similar to a second skin...

Embodiment Construction

[0028]In reference to FIG. 1, a top view of an article of footwear (e.g., a sandal) 100 is shown. The footwear 100 has a sole with a heel end or portion 102 and a toe end or portion 104. During use, a wearer of the footwear 100 positions his or her foot so that the heel of their foot contacts the sole of the footwear 100 at the heel end 102 and the toes of their foot contact the sole of the footwear 100 at the toe end 104. The sole may include a topsole 106 and a midsole 152, as discussed in greater detail herein.

[0029]The midsole 152 of the footwear 100 has a plurality of cuts (120, 122, 124, 126) disposed at the toe end 104 of the footwear 100. The cuts (120, 122, 124, 126) are positioned from the outer edge of the toe end 104 of the footwear 100 and extend inwards towards the heel end 102 of the footwear, as discussed in greater detail herein. Thus, the plurality of cuts (120, 122, 124, 126) form a plurality of planar platforms (131, 133, 135, 137, 139), as discussed in greater d...

Abstract

An article of footwear for increased athleticism utilizing independently articulating toe platforms. The footwear includes a first toe platform and a second toe platform disposed in a toe portion of the footwear that are either physically separated from one another via a cut in the toe portion or a flexible segment extending through the toe portion. A toe post is configured to engage between a first toe of a user's foot and a second toe of the user's foot. The first toe is configured to contact the first toe platform and the second toe is configured to contact the second toe platform. Additional toe platforms and/or toe posts may be utilized. The footwear may include a topsole, a midsole and an outsole. A stiffening agent may be disposed between the midsole and the outsole for resisting bending of the footwear and/or for helping protect the user's foot from external objects.

Description

BACKGROUND[0001]1. Field[0002]The present invention relates generally to footwear and improvements thereto and more particularly pertains to athletic footwear with independent toe articulation and improvements thereto.[0003]2. Description of the Related Art[0004]Designing footwear to balance both athleticism and wearability has proven a source of difficulty when utilizing conventional footwear design characteristics. As the athleticism of a shoe or sport sandal increases, the wearability or comfort level of such apparel often can diminish. During athletic movement, the foot of a user may be rapidly shifting, twisting or flexing in order to make frictional contact with the ground through the footwear in order to either propel the user in a desired direction or to abruptly halt the user. Any slippage or movement of the foot within the shoe results in a loss of athleticism for the user since the footwear is not optimally transmitting the forces from the user's foot to the ground below....
