Mo:

I bought a pair of Muck's last year....after buying 2 pair of LaCrosse's. I bought LaCrosse uninsulated and a pair of 1200gram.

The mucks "breathe"....and they're warmer than the 1200grams. They have neoprene uppers and rubber lowers.....and though I don't have too many issues with my feet sweating in regular shoes....I notice they don't sweat NEARLY as much as they do in the LaCrosse's. I have no issues with "stink" in my Mucks.
