Ok... I bought the ridge line for living outdoors in the winter.  I bought these Rigmasters since I likewise plan to find outdoor work in the winter, hopefully ranch work.  that means more than likely working with icy water, cleaning stalls, moving bales, and working around very large animals with hard stepping hooves.  all of which i know from experience can become painfully unpleasant under cold conditions with wimpy footwear.

I bought these in a 7.5 which is a half-size up from my normal boot size.  I typically run a 6.5 to 7 in shoes and lean toward 7 in boots.  I heard these run a little small, and i wanted to wear them with a thick wool sock (the Wigwam Merino Comfort Hiker 2-pack which I also recommend based on comfort and fit).  the 7.5 is perfect with the sock.  They fit much like the Ridge Line.

Appear sturdy yet are very lightweight for a work boot and appear well-insulated, we'll see.

The grommets at the top are just grommets, no option to lace through as with the Ridge Line, but they are nice and high and i don't think will cause problems (laces coming loose).

Maybe cowboy boots for summer, we'll see what the locals do!

Will update if my opinion changes when winter and work hit.
