On Cloudmonster 2 'Undyed Frost' (3ME10122035)

On Cloudmonster 2 'Undyed Frost'

The On Cloudmonster 2 in Undyed Frost is the most considered colorway in the series — and the one that requires the least color to say the most. While Triple Black commits to total darkness and Black Frost introduces cold contrast, Undyed Frost begins somewhere before color entirely: with the material itself, in its natural state, before the dye bath, before the process. What remains is something rare in performance footwear — a shoe that looks like it was made from the landscape rather than painted to match it.

Undyed Frost Colorway

Undyed is not a color — it is the absence of artificial color. On's undyed materials retain the natural hue of the fiber: a warm, raw off-white that varies subtly across the upper, carrying the texture and character of the yarn itself. No two pairs are exactly alike. This is not a flaw — it is the point. Frost then arrives as the one deliberate accent: the same icy blue-white that appears in Black Frost, but here it reads entirely differently — not as contrast against darkness, but as a crystalline complement to the natural warmth of the undyed base. Together, Undyed and Frost create a palette that is simultaneously the most minimal and the most materially rich in the Cloudmonster 2 lineup.

Sustainability Note

The undyed upper eliminates the dyeing process entirely, reducing water consumption and chemical use in production. This is On's commitment to material honesty — a shoe that performs at the highest level while carrying a lighter environmental footprint.
