I have a pair of these boots, the nice soft fawn colored ones, and love them so much that I wore them essentially as rain boots. They became stained by the extreme salt and deicer used by our road crews. I could not bare to send them to Goodwill so I just took the chance and threw then in the washer and then the drier. Now I offer this advice with no guarantee and it might not mess up other things so please use your head, but it worked perfectly for me. I saved my boots. I then hit them with some water proof spray. LIKE NEW inside and out. I hope this hint saves someone some $$$.
