User Review Summary
The Feiyran 4 is the latest advanced carbon‑plated running shoe in 361°’s Feiyran series. It features the upgraded KFLAME CQT midsole, using CO₂ supercritical foaming technology, delivering over 88% energy return and extremely low compression set (only 2–3% loss after 100 km in testing). The midsole uses a sandwich construction: a soft‑responsive top layer, a high‑density bottom layer, and a shovel‑shaped carbon plate in between, providing a strong rolling and propulsive sensation.
The upper is a blend of 50% carbon fiber and 30% eco‑friendly fiber, offering breathability and lightness, with fleece‑like reinforcement strips that enhance lockdown. The outsole uses RPU anti‑slip rubber with zoned abrasion resistance in the forefoot and heel, maintaining stable traction even on wet surfaces.
Overall, the ride is firm, responsive, and stable, suitable for runners pacing under 4:30/km for half‑marathon to full‑marathon racing and speed training. If you’re looking for a carbon‑plated shoe with high rebound, stable propulsion, and advanced performance, the Feiyran 4 is one of the most representative options from 361°.
