Yes We were told Sno Seal is SOP there are a few that do the polyurethane. Most skate manufactures do not recommend any additional waterproofing. This is not in their best interest if the skates last longer, that would equal less skate sales. I was hoping someone here might have experience with shoes or boots that are exposed to lots of moisture on a regular basis. We do dry the blades and skates after each skate both towel dry and have started to cool blow dry as well either hand dryer or hair dryer.. thanks for looking and taking the time to consider my issue.
