Asics MetaSpeed™ Sky Paris Red First, red is the color of racing intent in every language. The Asics MetaSpeed™ Sky Paris Red pairs that urgency with Asics' best stride-length optimization platform — FF TURBO PLUS foam and carbon geometry for the marathon course of one of the world's great running cities. Additionally, this is the MetaSpeed Sky Paris for runners who arrive at the start line already in race mode. The colorway of commitment, on the platform of performance. FF TURBO PLUS (PEBA) + Stride-Length Carbon Geometry: Asics Racing Science Additionally, fF TURBO PLUS is Asics' PEBA-based racing foam — lightweight, explosive, and tuned for the specific energy demands of marathon racing. The MetaSpeed Sky Paris uses a carbon plate geometry optimized for stride-length runners — typically mid-foot to heel strikers who accelerate by extending their stride rather than increasing cadence. The result is a racing shoe that amplifies the runner's natural mechanics. Race mesh upper: featherlight adaptive fit. ASICSGRIP rubber outsole. 171 g. 5 mm drop. 39.5 mm heel stack. Built for stride-length runners targeting marathon and half-marathon PRs. For Who? For runners whose natural mechanics favor stride length.
