Work shoes - whadya like?

Timely thread, especially with winter coming on.

Billy and I were just talking last night about some more serious work boots. Though I wear tennis shoes through good weather, I've got some hiking boots for the cold. With a new contract for 45 lb.+ a/c vent covers though, I need to consider some steel toes.

I don't really have a problem with sore feet at all, but standing on concrete all day every day takes its toll on my lower back. Any further comments on the boot suggestions offered along those lines? Dr. Scholl's inserts don't really do much for me.

Lots of research to do from this thread, thanks guys! I just hope they have something that won't make me look like a lesbian lumberjack.
