361° Flame 4.5 "Miro" — Elite Marathon Racing, Engineered for Speed
The 361° Flame 4.5 "Miro" (672532221-19) is an elite, professional-grade marathon racing shoe from 361°'s top-tier Flame series. Engineered for long-distance efficiency, it combines advanced carbon-plate propulsion with ultra-responsive supercritical cushioning. The sophisticated White/Silver "Miro" aesthetic — associated with birth and protection themes in 361°'s high-end lines — is as refined as the technology beneath it.
Performance Technology
- Propulsion System: QU!KBONE DYNAMIC carbon-fiber plate with a 3D arc-shaped design provides customized support and rolling propulsion through every stage of the gait cycle — from heel strike to toe-off.
- Cushioning: Double-layer QU!KFLAMECQT (FLAMECQT) supercritical foam midsole — nitrogen-infused for extreme energy return, lightweight impact protection, and enhanced springiness over marathon distances.
- Traction & Durability: Segmented RPU (Reactive Polyurethane) outsole — significantly more durable and slip-resistant than traditional rubber, suitable for professional racing and high-speed daily training.
- Advanced Upper: C!LK (Carbon Silk) technology — an ultra-breathable, lightweight fabric that facilitates rapid airflow to keep feet dry during intense marathon efforts.
- Lockdown: MORPHIT lacing system for a precise midfoot wrap, plus a padded tongue to reduce irritation during extended runs.
Design & Geometry
- Colorway: "Miro" — sophisticated White / Silver aesthetic, inspired by birth and protection themes in 361°'s high-end performance line.
- Stack Height: 33mm heel / 27mm forefoot
- Drop: 6mm — promotes a natural, efficient running economy
- Silhouette: Low-cut for unrestricted ankle mobility and aggressive toe-off mechanics

Fit Guide
The Flame 4.5 is built for a performance-oriented, snug lockdown. Most runners find it true to size (TTS). However, because the C!LK Carbon Silk upper has limited stretch compared to standard mesh, runners with wider feet should consider sizing up by 0.5.
