BrooksMen's Ghost 15 Neutral Running Shoe

How much grip do these have on grass, trails etc?

Curious what color the bottom or base of the shoe is. Is it navy colored or solid black?

Is the bottom of the sneaker navy colored or black? To be clear, I don't mean the underside of the sneaker that touches the ground.

Do they make a 10.5 Wide in the Black and White?
