Insulated boots....

Figured in a round about way they are shop equipment so.....

A while back there was a thread about boots....abodyjoe made mention of the Timberland boots he wears, but they are not insulated. Been working on thinning the sides of our roads. Right now the road is covered with a 3/4" thick sheet of ice that will probably be there until March or so...The boots I am wearing now, an older pair of Dunham boots just are not cutting it....my feet are like blocks of ice after standing in the snow/ice for a couple of hours....So what do you folks wear to keep your feet warm & toasty while outdoors.....

I realize that good foot ware is not cheap, have not spent under $150 on a pair of uninsulated boots in a very long time so don't be bashful if what you suggest is going to cost some coin.....
