The wide Mid in this selection
The EE designation is useful ordering information that is absent from several generic Lansing Mid titles. If you need length 10 with a wider fit, it is a better-defined starting point than an unspecified Lansing offer. EE still does not reveal the cap’s exact shape or the amount of room over the instep.
Dark Olive/Black distinguishes this listing visually from Raven/Tawny Olive. No evidence reviewed establishes a different protective design or a performance advantage from that color change. The KEEN sources cited here document the Lansing Mid family; match the exact style number and label for the color supplied.
A same-size Low comparison
The Cascade Brown/Fired Brick Lansing Low is also listed as 10 EE. It therefore offers a useful format comparison without immediately changing the stated length and width. That does not guarantee identical internal fit, and the Low should not inherit the waterproof claim from this Mid.
Choose between them according to whether the job requires boot coverage and whether the membrane-equipped format addresses your exposure. If you only need a lower shoe for permitted indoor work, a boot is not automatically the better purchase because it lists more features.
Before committing to the wider boot
Check the heel and instep along with forefoot clearance. A broad front can be comfortable while a loose rear allows unwanted movement; going back to a narrow size may simply reintroduce toe pressure. Another last can be a better solution than compromising either end.
A waterproof description is not a cold-weather temperature rating or a chemical-resistance specification. Where either matters, obtain the separate documentation rather than extrapolating from the Lansing name or the boot’s outdoor appearance.
