The timeline is the story here. On announced the Cloudmonster 3 in late February and launched it on March 5 at $190, the flagship of its max-cushion road line. Eight months later the shoe sits in the maker’s last-season sale, and the Twilight with White colourway is $120 on On’s US store. A current-generation trainer, cut by $70 before its first birthday.
Purple gets the deep cut. The quieter colourways cost more.

On rates the shoe’s own tech on its product page, and the ratings sketch the brief. Cushioning sits at medium, responsiveness at medium-high, stability at medium. In plain terms, this is the soft, bouncy end of the daily-trainer shelf rather than the firm, racy end, and the sale price now matches that brief instead of fighting it.
Three layers of CloudTec under the foot
The Cloudmonster name has always meant the biggest stack in On’s road range, and the 3 pushes it further. Its midsole runs three layers of CloudTec pods where the Cloudmonster 2 ran two, and the whole stack is dual-density Helion foam.

The softer layer takes the landing. The firmer one keeps the ride from going vague at mile eight. It’s a neutral shoe, built for everyday road miles rather than correction.
Those pods are hollow, and they run the full length of the shoe. It’s why the midsole looks like a row of cutouts from the side, and why the Monster has never been a shoe that blends in.
A nylon-blend Speedboard sits inside that foam, and the rocker curve is stronger than the old shoe’s. No carbon plate here.
Land on the pods, roll forward, and let the plate add some snap at toe-off instead of asking your calves to do every bit of the work. The recipe suits a daily trainer, a shoe that has to feel good on the tired Tuesday run as much as the fresh Sunday one.
The numbers stay sensible for something this tall. The stack measures 35 millimeters at the heel and 29 at the forefoot, a 6 millimeter drop. A men’s US 8.5 weighs 295 grams, light for this much foam.
A knit upper, woven in zones
The upper is an engineered knit, and the weave changes across the shoe. It sits tighter through the midfoot, where the foot needs holding, and opener over the toes, where heat builds. On redesigned the tongue and the fit over the 2, and the shoe comes in regular and Wide fits.

One caution on that Wide fit. It’s a separate product on On’s store, and its Twilight colourway runs $130, not $120. The $120 figure belongs to the standard fit alone, so check the fit name on the page before the cart does the math for you.
A women’s version runs alongside the men’s shoe at 240 grams in a US 7, with its own colourways and its own last-season pricing on its own product page. The hardware underneath matches: same triple-layer stack, same Speedboard, same 6 millimeter drop.
The rest of the colour chart
Twilight is the loud one, a deep purple over a white midsole, and it’s the colourway On cut deepest. Ivory with Limelight, Limelight with Seedling and Iceberg with Ivory each run $130, sixty dollars under list. Eclipse with Frost and Eclipse with Ivory sit at $150. One quirk worth knowing: On’s last-season page lists the shoe at $130 flat, and the Twilight product page itself goes $10 lower, so the colourway page is the price that counts.

The math holds up across the whole chart, which isn’t always true of a colourway sale. The $130 pairs are 32 percent under list, and even the $150 Eclipse pairs save $40 on a shoe that launched this year. Twilight is simply where the same arithmetic lands hardest, $70 off because purple is the colourway On needs to move.
None of this is a quiet launch offer on a brand-new shoe. It’s a last-season markdown, and the pricing shows it. Daily trainers wear out on a schedule whether the miles come easy or not, so a fresh pair at this level makes a clean stock-up buy before the old pair goes flat.

If your rotation needs a high-stack daily shoe and purple works for you, Twilight at $120 is the buy. The $130 colourways are the fallback for anyone who wants the same ride in a quieter colour.
