Well I am going to get some Mickey Mouse boots.Those are use by the Airborne and are warmest boots i have ever owned.In fact I was on a underground cable crew working out of town.We has dug a ditch the day before and some water has frozen overnight in it.I stood on it and broke threw filling one boot.Thought great,by the time I got back to the motel I was going to lose most of the days pay.I kept working just feeling the sloshing of the water and it was really cold out.Well I finished the work that day.Got back to the motel and emptied the boot out at the door.The water was steaming.No B.S.Certainly just the best boot I have ever owned.
