I love Boots - Navy/CG source Bates I believe ( Durashock — Wolverine). They are full grain leather and polishable. The USMC MEBs are Nubeck leather, and don’t take polish, just water proof spray. We have Farm, so I am always in boots doing something. My MEBs (in the picture above) are just for special occasions, when I have an important business meeting, or a church dinner.
Gore-Tex (or similar material) waterproofed boots would not have the “Air-Breather” circulation holes on inner arch just above the sole stictching.
The Danner MEBs in the picture above are a Hot Weather version, no Gore Tex, and include the air breather holes. They also come in All Weather GoreTex waterproof, without the breather holes.
The USMC RATs are nearly identical to the MEBs, but come with an outer plastic toe guard, a Steel or no Steel inner, and Temperate (Holes) or All-Weather Gore Tex.
Btw - I don’t think the Marines source the RATs anymore ... Only the MEBs I believe.
