HunterWomen's Original Tall Rain Boot

I usually wear an 8 do they run true to size? Are they form fitting, that's what I am looking for?

Are the matte boots not water resistent? (see comparison chart for water resistence level).

Im us 6. Which size should i buy ??6 B (M) its ok ???

Why does the description say 100% leather? These are supposed to be plastic rain boots. Are these guaranteed to be the real hunter boots?
