I've always worn a size 11 in boots as an adult and have worn Dingo boots most of my 50 years.
These boots came in fitting narrow and too long. I was able to add an insole for a better fit and dampen the leather to stretch out side to side.
Unfortunately, after wearing these lightly for only a month, the rivets in the harness are popping out or the heads have come off.
Overall, the boot itself is durable.
If and when I order these again, I will order a 10.5 Wide
