I'm a retired surveyor, worked in the mountains, worked on big heavy construction sites, owned a ranch with cattle, rode horses, packed with horses and shanks mare, hunted in 5 states, been on my feet most of my working career and retirement. I have 4 pairs of White's, Smoke Jumpers, worn by most wildfire crews, mine don't have the fire rating, and Packers for ranching and riding. White's is now owned by the a Japanese company, that also owns LaCross and Danner. The employees at White's (Spokane, WA.)said nothing has changed. They have added a few different models that I'm not familiar. They also are expensive, but they rebuild them, if used just for recreation they'll be around a lot of years. Check'em out on the internet. I have a pair of Nick's, also in Spokane, bought a pair of custom fitted Packers didn't fit from the git go, they had my money, and would do absolutely nothing to make it right.
