On Cloudmonster 2 Unisex Marathon Running Shoes – Ivory | Hay

On Cloudmonster 2 – Unisex Marathon Running Shoe

The On Cloudmonster 2 is On’s most cushioned and most energy-returning road running shoe — the second generation of the Cloudmonster platform, rebuilt from the ground up with a redesigned CloudTec® Phase midsole architecture, an upgraded Helion™ superfoam formulation, and a more responsive ride profile that retains every gram of the original’s legendary cushioning presence while delivering a more propulsive, more dynamic step. A shoe built for long-distance training and marathon performance, for runners who want maximum cushion without sacrificing ground feel or forward momentum.

Colorway

This style is offered in the Ivory | Hay colourway — the most tonally complex and most chromatically considered of the Cloudmonster 2 colourways, a three-part composition in ivory, hay-gradient, and deep chocolate that reads as warm, botanical, and quietly sophisticated in a family of otherwise high-contrast performance colourways. The upper’s primary body is rendered in a clean ivory — the warm off-white of unbleached linen, a white with enough warmth to read as organic and natural rather than clinical or optical, the same undyed register that grounds the Undyed | Black and Undyed | Flame but here with slightly more warmth in its undertone, the ivory as the composition’s resolved warm ground. Against this ivory ground, a wide diagonal stripe runs the full lateral perimeter from the rear heel counter to the toe-box edge in a continuous three-stage colour gradient: opening at the rear in a fresh yellow-green — the green of new spring growth, of lime zest, of the first warm morning of the year — transitioning through the mid-stripe into a warm, saturated lemon-yellow at the composition’s chromatic peak, before softening forward into a creamy, warm butter-yellow at the toe end, the gradient arriving at the front of the shoe in a colour close enough to the ivory upper that the two fields begin to merge at close range. The stripe carries the ON RUNNING wordmark in the same gradient register, the text and the colour field as a single architectural element. The colourway’s most unexpected element is the collar: a deep chocolate-brown — a warm, dark, almost purple-brown, the colour of cacao at its most roasted — that frames the shoe’s opening in a register completely outside the ivory-and-hay composition of the upper and stripe. The chocolate collar reads as the colourway’s grounding accent, the warm dark that makes the hay gradient’s lightness legible by contrast, the earth note beneath the spring-and-sun palette above. A lime-green lace — in the same fresh yellow-green as the stripe’s rear opening — threads through the ivory lacing system, the lace’s brightness punctuating the upper’s warmth with a single vivid horizontal note. A dark charcoal On logo anchors the lateral midfoot above the stripe. The ivory Cloudmonster 2 midsole below extends the upper’s warm white field in the same register, slightly warmer than the pure white of the Black | White, the midsole and upper reading as a continuous warm volume. A black outsole grounds the composition at contact point. Ivory above. Hay across the lateral. Chocolate at the collar. Lime at the lace.
