what is the difference between ghost 11 and ghost 12?
Brooks Ghost 11 vs Brooks Ghost 12 One difference between the two shoes is the look of the upper. ... Both the Ghost 11 and the Ghost 12 use DNA Loft and BioMoGo DNA foam in the midsole, so the feel didn't change from that iteration to this. You still get a ride that's soft but not mushy, responsive but not hard.
