If you have to be in wet conditions, I'd go leather. I worked for years in a soap plant, all kinds of nasty chemicals on the floor, sometimes inches deep. Only leather Wolverines would fit me and hold up. Where I am now, no water, cheaper (nylon) Wolverines, not as good of a boot. The better pairs would go two years in rotten service, this pair is two years in mild. My next pair will be a properly broken in leather Wolverine, no matter what they cost.
