A well fitted pair of waterproof shoes/boots can't be underestimated, when appropriate. Mostly boots, tho. Keep a spare change of shoes/boots in your vehicle. Preferably, next to a fresh change of clothes, socks and underwear, of course. People get opinionated about steel toes. Depends on the place you work and what you're working with. If it's too heavy, skip the steel. Firemen don't like cutting them off. Neither do medical workers. You won't mind the cutting part, you'll be too busy screaming or passed out.

As a young kid I worked in dad's garden during the heat of the summer, often barefoot. I think between the rich soil and cow manure, my feet grew a few extra sizes because of it. I wore a size 12 by age 13. IIRC, started wearing sneakers in the garden after that and my feet stopped growing at size 13.

Remember from the 1960s-early 1970s?

these things are getting nasty, but it's kinda like an experiment of how hard i can push these bastards.
