No claim is made to the dashed line regions on the shoe sole, including the inner diamond tread-region and the shoe upper portions shown as the dashed lines. Dashed lines indicate disclaimed portions forming no part of the claimed design, and the break-lines (dash-dot-dash) indicate the boundaries of the claimed portions. No claim is made to the top portion or side portions of the shoe, other than in claimed-lining in any of the figures, and this is shown as an environmental illustration only to aid the public.
