These boots are awesome!  I purchased them to traipse around some hiking trails in the Yukon.  I walked in mud and in puddles...not on purpose mind you, but at times I had no choice.  Nothing penetrated through these boots.  While the rest of me was cold and wet, my feet were warm and dry and comfortable.  They are true to size.  As others have said, they do not smell bad if you go without socks.  They are comfortable to walk in even when hiking all day.

They do have a sort of gamey smell when you buy them.  But if you have been purchasing non vegan shoes all along, you may not notice it.
