Ultrafly 6

Stability2026-02-01 · US · ReleaseChecked 2026-11-08

A lightly supportive road shoe for daily runs and walks. Ultrafly 6 adds cushioning and extends its medial post around the heel compared with Ultrafly 5. The multi-density ZipFoam midsole pairs a softer foot-facing layer with a firmer base. Broader outsole rubber coverage targets durability and traction, while breathable upper materials and a roomy toe box accommodate natural toe spread.
