The Brooks Ghost 18 and the Brooks Ghost Max 4 are two neutral training shoes from Brooks, but they are not after the same feel. The Ghost 18 is the standard versatile option, true to the series. The Ghost Max 4 is the max-cushion version, taller and softer.
The first difference is the geometry. The Ghost Max 4 sits taller, with a 40 / 34 mm stack versus 36 / 26 mm for the Ghost 18.
To maximize cushioning, the drop is lower on the Max (6 mm versus 10 mm for the standard version).
On weight, the difference is a tiny 5 g / 0.2 oz despite the Max’s extra height.
Both share DNA LOFT v3 foam. The Ghost 18 runs a balanced version that leans firm, for a stable ride. The Ghost Max 4 goes with a softer, nitrogen-infused foam, and above all a pronounced rocker (GlideRoll) that rolls the stride forward: the feel is plusher and more protective, at the cost of some responsiveness.
The Ghost 18 is the do-it-all shoe: great for beginners and daily training alike, it delivers in every scenario. The Ghost Max 4 is more for easy runs, recovery days and long distances, where its max cushioning and wide, stable base shine.
Both mesh uppers are comfortable. The Ghost 18 fits true to size; the Ghost Max 4 offers a roomier fit.
Ghost 18 or Ghost Max 4: which should you choose?
For most runners, the Ghost 18 is the more versatile choice, for beginners and daily training alike.
The Ghost Max 4 only makes sense if you put comfort and protection first on easy runs.
The short version: the Ghost 18 to do it all, the Ghost Max 4 for the plush feel.
