Depends on what I am doing. I most wear boots through. I have some Adidas running shows, some waterproof steel toe Cat boots. I also have an old pair of Docs with a steeltoe, not waterproof through. I have some winterized waterproof boots with extra traction for winter work. Nothing like slipping and falling on the ice a few times to teach you it really is worth paying the extra $80 for a nice pair of boots.
