Ideal for road running, cross training, the gym or wherever you might want to take them! Predecessor: Ghost 12 BALANCED, SOFT CUSHIONING: BioMoGo DNA and DNA LOFT cushioning work together to provide a just-right softness underfoot without losing responsiveness and durability - yet it feels lighter than ever.

SOFT, SECURE, FIT: The newly engineered mesh and 3D Fit Print practically disappears on your foot with strategically placed stretch and structure.
