Does anyone have good advice on how to keep the water out of full leather boots? My trusty Scarpas (not Goretex lined) always wet out after a couple of hours. I 'm not talking about Lake District bog walking, just ordinary grass and muddy, puddled tracks. Despite my assiduous application of waterproofing after each use, they always let the damp through. I have used only something called "Hydrobloc" provided by a local outdoors shop - it's a translucent waxy paste made by Zamberlan and was supposed to be just what I needed, but it doesn't work. I think I need some heavy duty stuff - any suggestions?
