Our Verdict
Brooks Glycerin Max 2
Brooks Ghost Max 4
The Brooks Glycerin Max 2 is a better shoe for most runners than the Brooks Ghost Max 4. Its taller stack delivers superior impact protection and rolls much more smoothly, delivering the true, luxurious max-cushion experience that's missing from the Ghost Max 4. However, the Ghost Max 4 is much lighter, lower to the ground, and far more stable, so it's the more approachable pick for beginners or those with stricter support needs who still want decent protection underfoot.
