The best pair of water proof boots I've owned were Dunam Duraflex. When I bought my first pair in 60s the store selling them had one in a glass tank with water 4" deep. Boot didn't leak. Treated once a year with Dow Corning , Shoe Saver liquid. They were light and very comfortable. They had only one draw back, the leather was soft. They weren't made for plowing through briar thickets like we have in this area.
