PERFORMANCE FOOTWEAR
The present invention is directed toward footwear including an upper connected to a sole structure. The upper includes two portions formed via compression molding in which textile layers are compressed to form a fabric laminate. One of the upper portions generally defines a seamless heel cup. The other upper portion generally defines a toe cage. The toe cage includes one or more integrated toe guides operable to position a toe of a wearer in a predetermined position within the cavity.

6 . The article of footwear of claim 5 , wherein at least one of the interior layer and the exterior layer comprises fabric.
7 . The article of footwear of claim 1 , wherein the upper comprises a planum portion including a seamless heel cup and a dorsum portion including a seamless toe cap, the toe cap being disposed above the toes of the foot.
8 . The article of footwear of claim 7 , wherein:
the toe cap comprises an undulating surface defined by a plurality of raised areas and recesses; and
the toes of the foot align with the raised areas of the toe cap.
9 . The article of footwear of claim 1 , wherein the toe guide is formed into the upper via compression molding.
10 . The article of footwear of claim 1 , wherein the toe guide is effective to deflect and receives the hallux, thereby separating it from the second toe.
11 . An article of footwear comprising:
a sole structure; and
an upper secured to the sole structure, the upper comprising:
a planum section including a seamless heel cup, and
a dorsum section including a toe cap,
wherein the planum section is connected to the dorsum section, the planum and dorsum sections cooperating to define a cavity operable to receive a foot of a wearer.
12 . The article of footwear of claim 11 , wherein at least one of the planum section and the dorsum section comprises a laminate including an interior layer facing the cavity, an exterior layer forming an exterior of the shoe, and an intermediate layer disposed between interior and exterior layers.
13 . The article of footwear of claim 12 , wherein at least one of the interior layer and the exterior layer comprises fabric.
14 . The article of footwear of claim 12 , wherein:
the interior layer comprises a synthetic fabric including an elastic fiber;
the intermediate layer comprises foam; and
the exterior layer comprises a synthetic fabric including an elastic fiber.
15 . The article of footwear of claim 14 , wherein the laminate is capable of being formed into a three-dimensional shape via compression molding.
16 . The article of footwear of claim 11 , wherein the toe cap is seamless.
17 . The article of footwear of claim 11 , wherein:
the sole structure includes a first, upper-facing surface and a second, ground-facing surface; and
the second surface of the sole structure further comprises a generally transverse groove, the groove defining a flection line of the sole structure.
18 . The article of footwear of claim 11 , wherein:
the toe cap cooperates with the planum portion to form a toe cage; and
the toe cap is a molded structure including a generally horizontal toe cover portion bordered by rim extending toward the sole structure.
19 . An article of footwear comprising:
a sole structure;
an upper coupled to the sole structure;
a toe cage operable to house a plurality of toes; and
a partition extending into the cavity, the partition operable to orient a toe of the plurality of toes in a predetermined position.
20 . The article of footwear of claim 19 , wherein:
the toe cage defines a ceiling; and
the partition extends distally from the ceiling toward the sole structure such that a gap exists between a distal end of the partition and sole structure.
21 . The article of footwear of claim 19 , wherein:
the upper defines a toe cage having a ceiling and a floor; and
the partition extends distally from the ceiling toward the floor such that a gap exists between a distal end of the partition and floor of the toe cage.
22 . The article of footwear of claim 21 , wherein the upper further includes a seamless heel cup.
23 . The article of footwear of claim 19 , wherein the article of footwear includes a hindfoot section, a midfoot section, and a forefoot section, the sections cooperating to define a cavity operable to receive a foot of a wearer.
24 . The article of footwear of claim 19 , wherein the partition is truncated.
