I've had leather boots leak with sno-seal and I've had leather boots that were exceptionally water-resistant when using sno-seal. (I'm loath to use the term "waterproof" with anything but rubber/neoprene) I am not sure why one pair fails and another stays dry. I think design and seam placement, and how these effect ware and tear, plays a role.
All one can do is try it and see what happens if one doesn't already have something else working for them.
