A sole component attachable to a bottom portion of an upper of an article of footwear, the sole component comprising a one-piece midsole having a medial side, a lateral side, a forefoot region, a midfoot region, and a heel region, the midsole comprising: an upper surface configured to face towards an interior of the article of footwear; a lower surface configured to face towards a ground surface when the article of footwear is in contact with the ground surface; and a sidewall extending around a periphery of the midsole, wherein the sidewall comprises: (i) a first wall portion comprising a plurality of convex elements extending out from the sidewall, wherein the plurality of convex elements provides additional resistance to compression at a region of the midsole proximate the first wall portion, (ii) a second wall portion comprising a plurality of concave elements extending into the sidewall, wherein the plurality of concave elements has a similar shape as the plurality of convex elements and reduces a volume of material at a region of the midsole proximate the second wall portion, and (iii) a transition region (335,345) where the wall elements (165,170) transition from being concave to convex; wherein each of the convex elements and the concave elements extends from a respective base to a respective distal end wall (185, 195), wherein for each element (165, 170) the area of said element (165, 170) at its base differs from the area of said element at its distal end wall (185, 195); and wherein the similar shape of the plurality of concave elements and the plurality of convex elements comprises a portion of a hexagonal polyhedron. an upper surface configured to face towards an interior of the article of footwear; a lower surface configured to face towards a ground surface when the article of footwear is in contact with the ground surface; and a sidewall extending around a periphery of the midsole, wherein the sidewall comprises: (i) a first wall portion comprising a plurality of convex elements extending out from the sidewall, wherein the plurality of convex elements provides additional resistance to compression at a region of the midsole proximate the first wall portion, (ii) a second wall portion comprising a plurality of concave elements extending into the sidewall, wherein the plurality of concave elements has a similar shape as the plurality of convex elements and reduces a volume of material at a region of the midsole proximate the second wall portion, and (iii) a transition region (335,345) where the wall elements (165,170) transition from being concave to convex; (i) a first wall portion comprising a plurality of convex elements extending out from the sidewall, wherein the plurality of convex elements provides additional resistance to compression at a region of the midsole proximate the first wall portion, (ii) a second wall portion comprising a plurality of concave elements extending into the sidewall, wherein the plurality of concave elements has a similar shape as the plurality of convex elements and reduces a volume of material at a region of the midsole proximate the second wall portion, and (iii) a transition region (335,345) where the wall elements (165,170) transition from being concave to convex; wherein each of the convex elements and the concave elements extends from a respective base to a respective distal end wall (185, 195), wherein for each element (165, 170) the area of said element (165, 170) at its base differs from the area of said element at its distal end wall (185, 195); and wherein the similar shape of the plurality of concave elements and the plurality of convex elements comprises a portion of a hexagonal polyhedron.
