Mark,
I to have seen them but never tried them,just might be a sleeper.

I do know that with their GUIDE SERIES line they stand behing them 100% no matter what.I bought a pair of boots from them 2-3 years ago after the 2nd year they started to leak so I called them and they said I could get my $ back or replace them.I took the cash and bought another pair of Danners.
