Brooks Ghost 14 GTX Black / Blackened Pearl / Aquaglass A lightweight GORE-TEX® Invisible Fit membrane is bonded directly to the upper for a light, flexible fit. The new, softer midsole and Segmented Crash Pad team up for easier flow from landing to toe-off. No matter how your foot strikes the ground, smooth transitions ensure comfort. If we got it right, you shouldn’t even notice transitions. Updated midsole is now 100% DNA LOFT cushioning for an even softer, smoother ride. DNA LOFT is our softest cushioning, yet remains durable and doesn’t feel too squishy. Our cushioning technologies all start with DNA because they react to your unique stride.
