Ghost Amp

Speed TrainerPlanned release 2026-07-15US

Ghost Amp is a lightweight road trainer built on the Ghost 18 last for daily miles and uptempo sessions. Nitrogen-infused DNA HYPE blends EVA cushioning with PEBA responsiveness, while a denser SpringRamp foam layer under the forefoot adds a springier toe-off without a carbon plate. A warp-knit upper secures the foot, and zoned rubber at the heel and forefoot protects high-wear areas while limiting outsole weight.

Show source notes

Release note: Achilles' August 26 announcement schedules sequential Japan sales from late August 2026, with some colors due mid-September. Use August at month precision, not the publication day as first sale. The historical July 15 US schedule is retained separately as planned timing; actual first-sale days remain unconfirmed.
Source note: Brooks US supports USD 150, 255.1 g, a 6 mm drop, DNA HYPE and SpringRamp; the exact Japan BRM4973 page lists JPY 19,800 and 250 g at 27 cm. Achilles supplies the late-August Japan schedule. Historical Fleet Feet specifications support 36/30 mm stack, zoned rubber and a non-carbon SpringRamp, but its normal route failed today. The manufacturer's 225 g / 27 cm and 28-22 mm sole-thickness figures remain an unresolved sample and measurement-scope issue, not replacements.
