Background

The present embodiments relate generally to articles of footwear, and, more particularly, to articles of footwear having an upper and a sole structure.

Articles of footwear generally include two primary elements: an upper and a sole structure. The upper may be formed from a variety of materials that are stitched or adhesively bonded together to form a void within the footwear for comfortably and securely receiving a foot. The sole structure is secured to a lower portion of the upper and is generally positioned between the foot and the ground. In many articles of footwear, including the athletic shoe types, the sole structure generally includes an insole, a midsole, and an outsole.

Disclosure of Invention

In one aspect, a sole structure includes a midsole component and an insole component. The midsole component includes a plurality of apertures arranged in an auxetic configuration. The midsole component is shaped to receive the inner base component, and a first density of the midsole component is different than a second density of the inner base component.

In another aspect, an article of footwear includes an upper and a sole structure having a midsole component and an insole component. The midsole component includes an outer surface and an inner surface. The outer surface includes a plurality of apertures arranged in an auxetic configuration. The inner surface includes a central recess that receives the inner sole member. At least one outer bottom component is attached to an outer surface of the midsole component.
