Believe it or not, but there are numerous "specialty" standards that footwear, and other clothing can attempt to meet; one of these has to do with not presenting an elestrically conductive path. There is also an opposing standard -one that requires conductivity- intended for anti-static worksites.
As far as "no steel toes",well, I have had jobs on both sides of that issue. Some require, some forbid, most don't really care.
What type of footwear does an electrician need? Something with a moderate amount of ankle support. Something with a firm footbed that will be comfortable during the hours you'll spend on a ladder- yet still has enough flex to allow you to climb and crawl. Something with a sole that has enough 'bite' to give you traction, buy won't collect mud or mark floors. Something that breathes in the summer, yet has room for extra socks in the winter.
Keep in mind that far more electricians are injured in trips and falls, than are ever hurt by electrical shock.
