yeah that's what was nice about the 155s.  you got the awesome steel toe piece and you also got a more normal and versatile din range.  now with the new ones you have to get the 10-18 bindings if you want the steel toe.  there are plenty of people who could use the steel toe and have no business using a 10-18 binding.  it would have been smart for them to make the 140's available with the steel toe piece.
