I wire these Boots years ago as a Teen and again when I worked as an Aircraft Tech and on both occasions they served me well.  But for many years I couldn't find a pair to replace the worn out Boots.  Until now and after reading the Amazon reviews on them stating that they run large on fit I ordered a 9.5 instead of the 10 I usually wear.  Well thanks Amazon Reviewers you were spot on the 9.5 fits great and the Boots are just as comfortable as I remember them being. So comfortable to walk or work in and I'm back in business
