ARTICLE OF FOOTWEAR WITH MIDSOLE HAVING HIGHER DENSITY PERIPHERAL PORTION

摘要

An article of footwear (10) includes an upper (12) and a sole assembly (14). The sole assembly includes a central member (30) of a first material having a first density with its medial (16) and lateral (18) sides having surface irregularities. A medial member (32) extends along a medial side of the central member and beneath a portion of the central member, and has a surface irregularity configured to mate and interlock with a surface irregularity of the central member. The medial member is formed of a second material having a density greater than the first density. A lateral member extends along a lateral side of the central member and beneath a portion of the central member, and has a surface irregularity configured to mate and interlock with a surface irregularity of the central member. The lateral member (34) is formed of a third material having a density greater than the first density.
