Max Cushion2023-08-03 · JP · Online launchChecked 2026-11-04

InfinityRN 4 brings ReactX foam to a cushioned daily road trainer, replacing the earlier React platform. A broad base and rocker-shaped sole support the transition from landing to toe-off. Its redesigned Flyknit upper adds toe room, midfoot support and a padded collar, with a water-resistant liner beneath. A durable Waffle outsole provides traction for everyday mileage.
