  • the upper cushioning member 130 also defines an upper portion 116a of the posterior projection 116. As shown, the upper portion 116a is formed where the top side 118 and the peripheral side 122 extend beyond the footbed 142 at the second end 114. Here, a distance from a portion of the peripheral side 122 on the medial side 16 and a portion of the peripheral side 122 on the lateral side 18 define a width of the projection 116 that tapers along a direction from the footbed 142 to the second end 114.

  • the upper side 150 of the lower cushioning member 132 includes a lower pocket 152 configured to receive a lower portion of the plate 110 when the sole structure 100 is assembled. Because the lower cushioning member 132 may be formed as a fragmentary structure including the anterior segment 134 and the posterior segment 136 spaced apart from each other by the gap 138, a first portion of the lower pocket 152 may be formed in the upper surface 150 of the anterior segment 134 and a second portion of the lower pocket 152 may be formed in the upper surface of the posterior segment 136.
  • the anterior segment 134 of the lower cushioning member 132 is disposed adjacent to the first end 112 of the cushioning element 106.
