Work boots....do you do construction?
Crocs.... so gay
Rockports and the like...they don't breath although I own two pair for the right occasion and working isn't it.
I wear running shoes,typically New Balance(I have really wide feet and they carrie multiple widths.
Look at it this way,running shoes are designed for impact,heavy and lots of it.Whaddya think we do all day everyday?While I love highly breathable shoes,don't forget about the type of socks you have on.Most these days are overbuilt.When I'm done for the day,they come off as soon as possible.
Even high end running shoes($120.00 and up) normally last about 500 miles.You ever wear a pedometer? In our line of work,the miles add up quick.
Someone mentioned prespray ruining shoes,change your prespray.
