THE SHORT ANSWER
Whichever your size still exists in. The Gel-Cumulus 24 is discontinued at retail, so remaining pairs sell against a thinning size run, while the Gel-Cumulus 25 has a full one. The Gel-Cumulus 24 also lists $10 lower.

Every spec, side by side
| Spec | Gel-Cumulus 24 | Gel-Cumulus 25 |
|---|---|---|
| FIT AND WEIGHT | ||
| Weight | 10.1 oz | 9.5 oz |
| The biggest single-year weight cut in the line, and the change reviewers led with. | ||
| Widths | D, 2E, 4E | D, 2E, 4E |
| Upper | Engineered mesh with a stretchy, slightly snug fit | Engineered mesh with improved ventilation and a thinner tongue |
| The tongue is about 23 percent thinner than the 24, which is the fit change owners of the older shoe notice first. | ||
| CUSHIONING GEOMETRY | ||
| Heel stack | 24 mm | 37.5 mm |
| The largest number on this page and the least real. Asics restated stack heights across its 2023 range on a full-shoe basis, and the Gel-Nimbus records on this site show the same 13 mm jump in the same year. The 25 did gain foam, roughly 15 percent more in the rearfoot per RunRepeat, but nothing like the published figures imply. The drop holds at 8 mm. | ||
| Forefoot stack | 16 mm | 29.5 mm |
| Drop | 8 mm | 8 mm |
| MATERIALS | ||
| Midsole | Full-length FF Blast | FF Blast Plus with a re-engineered PureGEL heel insert |
| FF Blast Plus is the softer, lighter formulation, and PureGEL replaces the old visible GEL unit with a lighter insert you cannot see. Together they are why the 25 is lighter than the 24 despite carrying more foam. | ||
| VALUE | ||
| List price at launch | $130 | $140 |

Questions runners ask
- Which is lighter, the Asics Gel-Cumulus 24 or the Gel-Cumulus 25?
- The Gel-Cumulus 25, by 0.6 oz in a men's US 9 (9.5 oz vs 10.1 oz).
- Did the price change between the Asics Gel-Cumulus 24 and the Gel-Cumulus 25?
- Yes. List price went up $10, from $130 to $140. Street prices differ: the older shoe usually sells under list once its successor ships.
- Do the Asics Gel-Cumulus 24 and Gel-Cumulus 25 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 24 carries over to the Gel-Cumulus 25.
- How do the stack heights compare?
- 24 mm heel and 16 mm forefoot on the Asics Gel-Cumulus 24, against 37.5 mm and 29.5 mm on the Gel-Cumulus 25. That is 13.5 mm more under the heel and 13.5 mm more under the forefoot. See the stack height note in the table above: the published figures changed convention mid-lineage.
- Is the Gel-Cumulus 25 still the newest Gel-Cumulus?
- No. The Gel-Cumulus 26 replaced it in 2024, so the Gel-Cumulus 25 now sells as an older model and usually below its $140 list price.
