Fantastic Steel Tip shoe for my husbands work.  We did have one problem the he wears a size 10 and when they came they were too small.  So we ordered an 11, they were too big.  Originally I found them and did not have an option of a half size until a 10.5 came available. The 10.5 fits perfectly.  Even though we had to return two, the right size was well worth the wait for this great shoe.  It is made very well.  My husband said for a Steel Tip it is comfortable and provides great support. He is on his feet for 12 hours at night standing.
I only can recommend a half size bigger than your normal size from the start.  I wish that was on the reviews I had available.  Overall very pleased.
