Patent ID: 11805842

Abstract:
Presented are footwear sole structures with split midsole designs having peripheral walls for lateral stability, footwear fabricated with such sole structures, and methods for making/using such footwear and/or sole structures. A sole structure for an article of footwear includes mating first and second midsole sections each having a respective midsole sidewall that extends between and adjoins respective upper and lower midsole surfaces. The first midsole section's lower surface has a first waveform geometry, such as an anteroposterior-undulating curviform wave, and the second midsole section's upper surface has a complementary, mirrored waveform geometry that seats therein and intermeshes with the first waveform geometry. The second midsole section includes one or more peripheral walls that extend upward from the second sidewall; inboard surfaces of the peripheral wall(s) abut outboard surfaces the first sidewall. An outsole, which defines the footwear's ground-contacting surface, is attached to the lower surface of the second midsole section.
