Old-School Style, Modern Tech. Tracing its lineage directly to the OG Clifton 1, the Clifton One9 takes old-school upper styling with an open-hole mesh underlay and gives it a fresh spin with the Clifton 9's supreme comfort and iconic tooling. Retro style doesn't mean sacrificing maximal comfort for everyday wear. The black and 'Aster Flower' upper is constructed from a porous mesh underlay, while TPU film overlays and synthetic toe cap and heel counters add structural support. Underfoot, advanced cushioning brings premium comfort to the retro-inspired design.
