Fantastic boot for just about an weather - especially cold
This is my third set of Timberland PRO boots - but this is my first Rigmaster Wellingtons. So far these are my favorite for field work where they need to be taken off and on (going into and out of a clean office regularly) - they are easy to get in and out of but they aren't too loose. They are perfect for cold weather, better than the other Timberlands that I own. They get a bit warm indoors and on hot days but I'm never sweltering. By now I've gotten used to the warmth and it doesn't bother met at all, even after hours of surveying on broken rock in the field during +70 degree weather. Absolutely no water has gotten through my boots and I'm frequently walking through ankle-deep water, snow, and mud. My only gripe has to do with the ladder lock - I work almost entirely in a rough terrain environment without few ladders, it tends to get hung up very easily on rocks. I'm sure for anyone working around ladders it's fantastic, but for hiking it's obnoxious.Update (8-2-16): I bought these about a year and half ago, and they are just now starting to wear out. The threads are starting to pop near the heel patch on both boots. There's still plenty of tread on the sole and the tips are pretty worn down but serviceable. I'm ordering my second pair of Rigmaster today to replace the ones I wore out. All things said, these are the best work boots I've ever owned. Great traction, very comfortable, easy to pull on and take off (unlike those monster Matterhorns common in mining).They are totally water proof. I was skeptical about buying "wellington" pull up boots, since lace-up boots and Xtratufs are industry standard for mining - but both are uncomfortable and a pain to put on. I have big calves, small ankles, and big heels. Those dimensions make the Extratuffs cut into my calves and the lace up boots are a pain to take on and off, especially after they have some miles on them. These wellington pull up boots were perfect - easy to take on and off, snug when I'm hiking in the pit, and I've never had water issues since I wasn't plodding through more than 8 inches of water.They are also insulated just well enough to be good for working for several hours in the arctic circle but breathable enough for working in moderate to warm temperatures without getting too hot. I wouldn't recommend these for desert weather as they do have about 600g per boot of Thinsulate, so you'll want to go with an boot that lacks insulation for that, naturally. I bring it up because the description for most Timberland boots doesn't mention if they are insulated or not, and how much insulation they have.I liked my last pair enough that I hate to retire them - but they are just boots afterall. Two thumbs up. I highly recommend these boots for anyone working in colder environments.
