Which is lighter, the Asics Gel-Cumulus 21 or the Gel-Cumulus 22?

Neither by a meaningful margin. Both weigh about 10.1 oz in a men's US 9.

Do the Asics Gel-Cumulus 21 and Gel-Cumulus 22 come in the same widths?

Yes. Both run in D, 2E, 4E for men's sizes, so a width that fit in the Gel-Cumulus 21 carries over to the Gel-Cumulus 22.

How do the stack heights compare?

29 mm heel and 19 mm forefoot on the Asics Gel-Cumulus 21, against 23 mm and 13 mm on the Gel-Cumulus 22. That is 6 mm less under the heel and 6 mm less under the forefoot. See the stack height note in the table above: the published figures changed convention mid-lineage.

Is the Gel-Cumulus 22 still the newest Gel-Cumulus?

No. The Gel-Cumulus 23 replaced it in 2021, so the Gel-Cumulus 22 now sells as an older model and usually below its $120 list price.

THE SHORT ANSWER

Whichever your size still exists in. The Gel-Cumulus 21 is discontinued at retail, so remaining pairs sell against a thinning size run, while the Gel-Cumulus 22 has a full one.

	Not 6 mm of foam removed. Asics restated its stack figures on a lower basis across the range in 2020, the same shift the Gel-Nimbus records show a year later. The drop holds at 10 mm and the platform is carried over, so the at-a-glance chip on this handoff overstates the change.
