A size alternative within a similar listing group
This record and the brown/black/tan size 11 page describe the same broad format. They do not establish separate model generations. If replacing a known pair, use its label or style number to confirm the match instead of relying on color and the waterproof keyword.
Plan around the actual exposure
Use the related size 11 page to locate another size of a similarly described boot. For wet work, confirm the opening height and care instructions as well as the seller’s waterproof claim. Occasional rain and water entering above the collar are different exposures.
