Brooks Ghost 17 vs Brooks Ghost 18:
Which to Choose

Under the foot these two are nearly indistinguishable. Both run on Brooks' DNA Loft v3 foam, both carry a 12mm heel-to-toe drop, both are plate-free, and both deliver the same firm-but-controlled, planted transition that rolls quietly from heel to toe without any aggressive rocker pushing you forward. Cushioning, stability, responsiveness, and pace all land in the same place on our scale, and both are neutral shoes with a wide, posting-free platform that stays reassuringly stable for the category. Weight is effectively a wash — the Ghost 18 comes in at 289g in a men's US 9 and the Ghost 17 at about 290g — and stack heights are within a millimeter or two of each other, so neither feels lower or more substantial than the other. The one genuine, tangible upgrade is the upper: the Ghost 18 moves to a triple jacquard engineered mesh with a soft flat-knit tongue and an Ortholite X-60 sockliner, which shed the somewhat stiff, over-structured hold of the Ghost 17 in favor of a softer, more accommodating, slightly more premium wrap. Ride-wise there's a faint sense that the 18's heel is a touch smoother and more forgiving, but the muted, unspringy rebound that defines both shoes is unchanged — push either past a steady effort and the foam goes flat rather than lively. In practice: same engine, gently refreshed cabin.
