I bought Danner Canadian boots and they do not fit my feet. They are size 9.5 and 600 grams. I only wore them for about a week or so around the house, they are like new. I did put Danner boot grease and waterproofing on them. If I did not do that, I would have sent them back. Dumb mistake, but Danner always did fit, so I never tried them on first. $ 280
