Our Verdict
Brooks Ghost 18
Brooks Ghost Amp
The Brooks Ghost Amp is the more versatile younger sibling of the Brooks Ghost 18, and it's the better shoe for most runners. It's more cushioned, more energetic, and more fun underfoot across everything from easy runs to longer efforts. Though the Ghost 18 is slightly more stable overall, most runners won't notice the difference, and its heavier build and duller midsole mean it can't match the Amp's livelier ride or broader performance range.
