Dayton boot Size 9 -1/2 3E made in canada

New condition Old stock I am US 9-9.5 currently wearing a 8-1/2. Sizing suggestion from Google Depending on the style of boot, men will fit 1 full size down from their North American size. Ladies will generally fit 3 sizes down. In other words, a Man with a North American size 9 foot will fit a Dayton 8. A woman who is normally a North American size 7 will fit a Dayton 4.
