Hey all glad to share and see that some of you know these boots already. I don't know about the wescos or danners but my Whites brand new were supple and tuff as hell at the same time right out of the box. The height of the heel was something i needed to get used to. (i'm 5'8" in my socks but i'm pushing 6' in these!!) As far as the stiffness the only thing I had to get used to was the sole that seemed not to bend. But after a couple days of living in them they break in (or maybe that was my feet breaking in) but never get flimsy. they come standard in a height of 10" but they go up to 16".
Despo- Check out their "Lineman". Is that like your old wesco's?
They also make a lined versio called their hunter.
And if you want to go all winter no mercy they have a line called "PACS". I own a pair of these as well. Lets just say Sorell's are turds with a lining compared to these.
