Portion of a shoe outsole

FIG. 1 is a bottom plan view of a portion of a shoe outsole showing my new design;

FIG. 2 is a perspective view thereof; and,

FIG. 3 is a rear perspective view thereof.

The broken circles and ovals in the views, along with the broken lines around the full-time illustration of the design, form the boundaries of the claimed design. The broken lines showing the remainder of the shoe illustrate the environment in which the design resides. Neither the broken lines, nor the areas within the circles and ovals, form any part of the claimed design.
