Fli-Lyte 4

Daily Trainer2021-08-31 · US · AnnouncedChecked 2026-11-10

Fli-Lyte 4 is a light neutral road trainer for everyday runs and faster sessions, with occasional gym use. This generation introduces ZipFoam and a wider platform. Recycled engineered mesh removes overlays, while loop-style lace stays help hold the tongue in place. A roomy toe box lets the toes spread naturally, and added outsole rubber improves grip and durability.
