Can't have dirt yet? What if the shoes are a little dirty to begin with ?

No problem. It mainly depends on whether the outdoor shoes are of the type with mud. You can see these terms on the immigration website.
If time permits, file your application.
Multiple pairs should not be declared, but I was carrying a pair of Cat shoes at the time and he asked me to open the box and check them because they looked like hiking boots.
