1. A sole structure for an article of footwear comprising:
- a first midsole element formed from a first material having a first degree of compressibility;
wherein the first midsole element has an upper are with a depression;
a second midsole element formed from a second material having a second degree of compressibility less than the first degree of compressibility, the second midsole element having an upper surface and an opposite lower surface, the lower surface being positioned adjacent to the upper area of the first midsole element, the second material contacting the upper area of the first midsole element, the second midsole element defining a plurality of apertures that extend from the upper surface to the lower surface and completely through the second midsole element, a lower portion of each of the apertures being located adjacent to the upper area of the first midsole element; and
wherein the sole structure has a heel region;
wherein the second midsole element includes a protrusion that extends downward from the lower surface of the second midsole element and into the depression in the upper area of the first midsole element, the protrusion being located at a central portion of the heel region of the sole structure, and wherein at least one of the apertures extends through the protrusion.

Abstract
A sole structure of an article of footwear includes a foam element and a non-foam element with different compressibilities. The foam element is positioned adjacent to the non-foam element. The non-foam element may define a plurality of apertures, with ends of at least a portion of the apertures being located adjacent to a lower area of the foam element. The non-foam element may also form a protrusion that may be located in a central area of the non-foam element and extends into the foam element. In addition, a portion of the non-foam element that forms a side of the sole structure may define an indentation.

12. A sole structure for an article of footwear comprising:
-
a first midsole element formed from a first material having a first degree of compressibility; a second midsole element formed from a second material having a second degree of compressibility less than the first degree of compressibility, the first midsole element having an upper surface and an opposite lower surface, the lower surface being positioned adjacent to an upper surface of the second midsole element, the first material contacting the upper surface of the second midsole element; and wherein the upper surface of the second midsole element defines a series of protrusions extending in a direction from a lateral side to a medial side of the sole structure; wherein the lower surface of the first midsole element defines a series of depressions extending in the direction from the lateral side to the medial side of the sole structure;
wherein each of the protrusions of the series of protrusions extends into a respective one of the depressions of the series of depressions establishing a wavy interface extending in the direction from the lateral side to the medial side of the sole structure, the series of protrusions and the series of depressions being located at a portion of a heel region of the sole structure. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
