Yes they do,,???
Kulien, Viberg, Buffalo, White, Wesco. Are all waterproof if kept oiled and taken care of.
Unless the boots are rubber, they are only water resistant. If you don't believe me, try standing in a foot of water for an hour or so. Any material that breathes is also water permeable.
I agree with Glen here. I started wearing Kuliens when I was falling timber on the west coast, and worked in the rain primarily, especially in Southeast Alaska(13 feet of rain average per year). I couldn't stand rubber boots, as I like the toughness and stability of leathers, especially cork (caulked) boots. I mostly ran wesco, off the shelf, corks in Montany and Idaho, but they were no match for west coast wetness, no matter how much I greased them. The leather that Kulien uses is premium, and if kept oiled or greased regularly, they are badass. Not once did my feet get wet even in my four years in Alaska. Now that I am a tree climber, and need vibram soles, the kuliens have only gotten my feet wet when I am doing a tree job by a ditch and am constantly wading in the water and it gets over the top of them...no bs, if it was just a few inches of water, and I was not standing in it for hours, my feet would not get wet. The vibram soles on them however, seem to be wearing out way too fast, so with the price that I paid for them, and with winter coming on (I wanted some insulation for warmth) I decided to try a custom built pair of Wesco "highliners"

My Brother, who is a west coast timber faller, had tried a custom pair of their cork boots with the cambrelle and thinsulate lining, and said he loved them...which is another reason I decided to give them a try. Here are the specs of the boots that I ordered, and will be receiving them in a couple of weeks:CUSTOM FIT HIGHLINER®
STYLE BK9716CT100R (Size: Send Me A Form)
+Single-Tone:Black
+16" Height
+Side Flaps (standard)
+Lace-To-Toe
+Cambrelle with Thinsulate Lining

+Standard Heel Height
+Brass Hooks & Eyelets
+Lightweight Black Upper Stitching
+Black Kevlar Heavy Upper Stitching
+Black Kevlar Outsole Stitching
+Black Nylon Laces
+Rush Fee
They were $838! Now, keep in mind that these are custom built for my feet, with an added heel length on the right boot, with a rush order fee of $125. The guys in the custom fit department were very helpful in choosing my options. I will report back when I get them, and have a chance to try them out for a while, but I am optomistic that they will be badass.
In the old days a product called 'Shoe Goo'. I'm surprised the retailers selling arborist supplies haven't caught on to this. A special light-weight boot with carpet soles would be a God Send for the arborist trimming in a wet canopy a lot.
I use shoo goo all the time, for just about any application. If I really want something to hold in the right application, I use either freesole, or sealall. Sealall even works for gluing the annoying caps on piggyback gas jugs, as it is fuel resistant.
