SkechersGhenter Bronaugh mens Work Shoe

Are these actually called “food service?”

I’m pregnant and my feet swell, what size should I get if I’m naturally a 9?

Do they come in any other colors besides black? Would like navy blue for wearing with blue jeans.

I seen a review that these are fake skechers and not slip resistant! Is that true? Can i wear these working in a resturant 8+ hours?
