I worked as a forester for the Forest Service adjacent to Yellowstone Park for 3 years and the Idaho Department of Lands for 5 years, spending 90% of my time in the field, wet or dry. I always wore a pair of leather White's boots, made in Spokane,WA. Tried many different brands of waterproof concoctions. SnowSeal worked the best but had a bad effect on any threads. I finally mixed SnowSeal with Mink oil and that worked. Now the bee's wax and pine tar mix is very popular. It's one thing to get leather wet once in a while vs leather boots walking in wet weather day in and day out, to find a good waterproof material. Old timers made their own, 40% bear fat,40% mutton tallow, 20% pine tar. Hard to find that today.
