1. A sole for an article of footwear, comprising:
- an undulating foam midsole having a heel portion, a forefoot portion, a medial sidewall and a lateral sidewall,wherein the midsole is sinusoidal along at least a portion of a length of the midsole such that a plurality of spaced apart peaks extend across an entire width of the midsole from the medial sidewall to the lateral sidewall and a plurality of spaced apart troughs extend across the entire width of the midsole from the medial sidewall to the lateral sidewall,wherein more than one peak of the plurality of peaks have a greater height at the medial and lateral sidewalls of the midsole than in an area between the medial and lateral sidewalls,wherein more than one peak of the plurality of peaks have a gap devoid of material disposed directly below each of the peaks, wherein the gaps each extend across the entire width of the midsole,wherein at least one trough of the plurality of troughs has a gap devoid of material disposed directly above the at least one trough, wherein the at least one gap extends across the entire width of the midsole,wherein at least a portion of an outer face of a trough of the plurality of troughs along at least one of the medial sidewall and the lateral sidewall is nonplanar to an apex of a directly adjacent peak of the plurality of peaks, andwherein the midsole extends across an entire width of the sole; and
a plate disposed on the midsole, wherein at least one apex of a peak of the plurality of peaks extends above a bottom surface of the plate and contacts both a medial side surface and a lateral side surface of the plate.
