DickiesMen's Work Trousers Slim Fit Tapered Leg Casual Pants

do these fit somewhat similar to skinny pants?

Compared to the original 874 pants, are they more stretchy(giving)? I'm looking for Dickies cut like the originals & more flexible around quads.

What's the difference between this and dickies 830F? Seems like they are both flex, slim tapered, but only difference is this one has a leg pocket.

I wear a 30w in original dickes, but on the skinny fit the 30w was too tight to put on. should i buy a 30w in this model or go larger?
