I am pretty sure I looked on the Redwing site above before I ordered the ones I got today and sent an e-mail but don't think I got a note back. Could be a mistake on my part.
Either way, I got the black Tibet today and just HATE the black color.....I know Color don't matter.
I have this boot on now and can't imagine needing or wanting anything any stiffer or higher than this.
May give you a call tomorrow.
Thanks for the info,
Archer
