Do not lose the width detail at checkout
The title names size 11 without a Wide suffix. Another Second Shift listing supplies Black 11 Wide. If your previous pair was wide, choosing this brown offer by size number alone could overlook the width selection. Conversely, a buyer who does not need extra volume should not assume the Wide offer is an upgrade. Check the complete size-and-width combination after changing any seller option.
What stays consistent in the comparison
These offers are variants of the same named CAT model rather than separate recommendations for different trades. The official Second Shift source describes an industrial lace-up with steel-toe, EH and slip-resistant features. Match the exact boot to that documentation before using the safety properties in a purchasing decision; the marketplace size label is not the safety label.
A change of length versus a change of format
Dark Brown 10.5 is the adjacent nominal length in this group. Compare it only if your measured length or on-foot result gives a reason; sizing down to tighten the heel can leave the protected forefoot crowded. If the repeated issue is lack of adjustment through the ankle, keep a lace-up in the comparison instead of switching to a fixed-volume pull-on solely for faster entry.
Second Shift and Pit Boss are both recognizable lace-up work-boot directions, but their shared format does not guarantee matching lasts. A cross-brand comparison should investigate a different shape, not assume that both size 11 labels describe the same interior.
