1. An apparatus comprises:
a heel section having an upper heel portion positioned substantially over a lower heel portion; a mid-foot section having a top mid-foot portion positioned substantially over a lower mid-foot portion; and a toe section having an upper toe portion positioned substantially over a lower toe portion, wherein:
the upper heel portion, the upper mid-foot portion, and the upper toe portion collectively have a first geometric shape having a first slope along an inner edge of the apparatus from a front edge of the apparatus to approximately a rear edge of the apparatus, a second slope from the inner edge of the apparatus to an outer edge of the apparatus, and a third slope along the outer edge of the apparatus from the front edge of the apparatus to the approximately a rear edge of the apparatus, wherein the first slope is greater than the third slope, and wherein the second slope has a variable angle from the front edge of the apparatus to the approximate rear edge of the apparatus that is based on a difference between the first slope and the third slope; andthe lower heel portion, the lower mid-foot portion, and the lower toe portion collectively have a second geometric shape having a fourth slope along the inner edge of the apparatus from the front edge of the apparatus to the approximately a rear edge of the apparatus, a fifth slope from the inner edge of the apparatus to an outer edge of the apparatus, and a sixth slope along the outer edge of the apparatus from the front edge of the apparatus to the approximately a rear edge of the apparatus, wherein the fourth slope is greater than the sixth slope, and wherein the fifth slope has a second variable angle from the front edge of the apparatus to the approximately a rear edge of the apparatus that is based on a difference between the fourth slope and the sixth slope. |
