Query: Greatest boot I have ever owned

I grew up in Buffalo, NY I have been thru lots of winter boots. I have destroyed, lost and abused many winter boots. I'm 60 years old now and still live to play in the snow. I do not ski. I purchased my Sorel boots in January 2000. We went to the winter fest in Ottawa Canada. The temp was 10F most days. We walked all around Ottawa for 5 days, my feet stayed warm and dry. Last winter I went to Montreal. I got there in the middle of the worst snow storm to hit in 34 years. I walked all around "Old City Montreal" for 3 days. Again my feet stayed warm and dry, At nite the temp went down to 15F. I coat the boots twice with "Neets Foot Oil" at the start of every winter. Water has never gotten into my feet. I gave a pair of Sorel boots to 3 other people. They also love them. They are The best winter boots I have ever owned.George J. Dvorak IIParkesburg, PA
