The Brooks Revel 9 and the Brooks Ghost 18 are two neutral training shoes from Brooks, but they don’t play in the same category.
The Revel 9 is the entry-level option, built to get you started without breaking the bank. The Ghost 18 is the series’ premium safe bet, more polished across the board.
The Revel 9 is lighter (20 g / 0.7 oz less) and lower (-3 mm).
Both have a 10 mm drop.
So the Ghost packs more foam underfoot than the Revel.
The difference mostly comes down to the foam. The Revel 9 debuts DNA LOFT v2, lighter and a bit firmer, decent but without the softness of the tier above. The Ghost 18 moves to DNA LOFT v3, nitrogen-infused, softer and more comfortable: it stays a step above in cushioning, comfort and responsiveness.
In terms of ride feel, the Revel 9 is firm and stable, great for getting started or for tight budgets. The Ghost 18 is more versatile and more comfortable, at home anywhere from easy runs to daily training.
Both mesh uppers fit well. The Revel 9 is more breathable; the Ghost 18 has the more refined finish.
Revel 9 or Ghost 18: which should you choose?
It’s a question of budget. The Revel 9 is enough to get started, or as an affordable training pair that does the job.
The Ghost 18 is noticeably pricier, about $50 more, but it’s worth the gap as soon as you run regularly.
Bottom line: the Revel for the budget, the Ghost for versatility over the long haul.
