Claim 0:
1. A track pad comprising:
a shoe member including a ground engaging surface, and defining a track chain traveling direction, a lateral direction perpendicular to the track chain traveling direction, and a vertical direction perpendicular to both the lateral direction, and the track chain traveling direction, the shoe member further defining a first lateral end, a second lateral end, a front end along the track chain traveling direction, and a rear end along the track chain traveling direction, a lateral distance from the first lateral end to the second lateral end, and a width from the front end to the rear end along the track chain traveling direction that is greater than the lateral distance; and
a first link member extending upwardly from the shoe member including
a first lug member extending from the first link member in a first direction parallel to the track chain traveling direction, a second lug member and a third lug member both extending from the first link member in a second direction opposite of the first direction;

wherein the track pad defines a first side cavity that extends from the first lateral end toward the second lateral end, the first side cavity being asymmetrical about a midplane of the track pad extending from the first lateral end to the second lateral end, the first side cavity jogging
increasingly from the front end toward the rear end along the track chain traveling direction, and
downwardly from the first lateral end toward the ground engaging surface.
