Brooks Ghost 18 vs Brooks Adrenaline GTS 25:
Which to Choose

On paper these two are nearly interchangeable, and that's honest rather than a marketing accident. Both use nitrogen-infused DNA Loft v3 EVA, both skip a propulsion plate, both wear a breathable engineered knit/mesh upper, and both share the same scorecard for cushioning (generous but controlled, not pillowy), responsiveness (modest, smooth over springy), and pace (happiest around 5:30–6:30 min/km, topping out near 5:00 min/km before the weight catches up). Stack heights are effectively the same — the Ghost sits at 37 mm heel / 25 mm forefoot, the Adrenaline at 36 mm heel / 26 mm forefoot — and weight is nearly a wash, with the Ghost at 289 g and the Adrenaline at 295 g in a men's US 9. The two real, measurable differences are drop and stability. The Ghost carries a 12 mm heel-to-toe offset versus the Adrenaline's 10 mm, so the Ghost tilts a touch more heel-friendly and takes a little more load off the calves, while the Adrenaline's slightly lower offset sits marginally flatter. The bigger divergence is structural: the Ghost is a stable neutral platform with no correction built in, whereas the Adrenaline's GuideRails act as quiet guardrails on either side of the heel, keeping an overpronating stride in line — most noticeable late in a run as you fatigue — without the intrusive feel of an old-school medial post. Ride character is otherwise the same story from both: planted, smooth, no-drama transitions that reward consistency and hold you back if you try to run fast.
