a body having a heel portion, a sole portion, a toe portion, a top-line portion, and a face portion, wherein said sole portion extends rearwardly from a lower end of said face portion; wherein the face portion includes an ideal striking location that defines the origin of a coordinate system in which an x-axis is tangential to the face portion at the ideal striking location and is parallel to a ground plane when the body is in a normal address position, a y-axis extends perpendicular to the x-axis and is also parallel to the ground plane, and a z-axis extends perpendicular to the ground plane, wherein a positive x-axis extends toward the heel portion from the origin, a positive y-axis extends rearwardly from the origin, and a positive z-axis extends upwardly from the origin; wherein the body includes a central region in which −25 mm<x<25 mm; wherein the sole portion that is contained within the central region includes a forward sole region located adjacent to the face portion and a sole bar located rearward of the forward sole region, with the forward sole region defining a wall having a minimum forward sole thickness TFS and the sole bar defining a body having a maximum sole bar thickness TSB, such that 0.05<TFS/TSB<0.4; wherein the sole bar defines a first channel extending in a substantially heel-to-toe direction of the sole portion and having a first channel opening located on a bottom surface of the sole bar. |
