On Cloudmonster 2 Unisex Marathon Running Shoes – Mineral | Blueberry

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 Mineral | Blueberry colourway — the coolest-temperature and most tonally refined expression in the Cloudmonster 2 range, a dual cool-colour composition that reads as atmospheric, considered, and quietly striking in contrast to the higher-contrast binary colourways in the family. The upper’s primary body is rendered in a cool mineral green: a desaturated, blue-leaning mint — the green of glacial water seen at depth, of sea glass worn smooth, of the interior of a wave at the moment before it breaks — a green that has more blue in it than warmth, a green that reads as cool and elemental rather than botanical or vivid. The mineral field covers the full upper from toe-box to collar in its muted, atmospheric register, the colour’s low saturation giving it a surface depth and material presence that higher-chroma colours cannot achieve. Against this mineral ground, a horizontal blueberry stripe runs the full lateral perimeter at mid-upper height: a medium, slightly purple-toned blue — the blue of ripe blueberries, of dusk light through thin cloud, of the moment between blue and violet on a clear evening — a blue that is warmer and more present than the mineral’s cool restraint, the stripe as a horizontal chromatic anchor that grounds the mineral’s atmospheric quality with a more decisive colour statement. The ON RUNNING wordmark is printed in clean white on the blueberry stripe, the text at maximum legibility against the stripe’s mid-blue ground. A large white On circular logo anchors the lateral midfoot above the stripe, the brand mark in clean white against the mineral upper — the colourway’s most graphically direct element, the white circle as both a brand declaration and a tonal counterpoint to the cool dual-colour composition. A pale sage-to-cream transition zone at the lower lateral perimeter — where the mineral upper meets the white midsole boundary — introduces a soft, almost imperceptible third tone that prevents the transition from upper to midsole from being abrupt, the lower edge of the upper fading toward the midsole’s white register at close range. Black collar binding and a black-and-white flecked performance lace ground the shoe’s upper in a performance-dark accent at the entry point and lacing system. The pure white Cloudmonster 2 midsole extends cleanly below, the square-aperture CloudTec® Phase architecture in bright white providing the strongest chromatic contrast in the composition: the warm-cool mineral above, the clean white below. A black outsole grounds the composition at contact point. Mineral above. Blueberry at the stripe. White below.
