THE SHORT ANSWER
Two updates and 2 years separate the Asics Gel-Cumulus 23 from the Gel-Cumulus 25. Net change: 0.4 oz lighter, 14.5 mm more heel stack, a drop change from 10 mm to 8 mm, a new midsole, $20 more at list. The Gel-Cumulus 24 is where the character changed, and that is the update Gel-Cumulus 23 owners notice first.

Or buy the Gel-Cumulus 24 instead?
The Gel-Cumulus 24 is worth a look only if you want the ride it introduced, because that is the update that changed the shoe. Buying it to soften the jump does not work: you would be adapting to the same change either way, just at an older spec.

Questions runners ask
- Can I go straight from the Asics Gel-Cumulus 23 to the Gel-Cumulus 25 and skip the Gel-Cumulus 24?
- Yes, but going Gel-Cumulus 23 to Gel-Cumulus 25 means taking one change in a single step: the Gel-Cumulus 24 is where the ride moved. The drop also goes 10 mm to 8 mm across the jump, so give it a week of easy running.
- How much did the weight change across these two updates?
- 0.4 oz off in total, 9.9 oz to 9.5 oz in a men's US 9. The Gel-Cumulus 24 took it to 10.1 oz first.
- Is the Gel-Cumulus 24 the better buy than either of these?
- On paper it splits them: 10.1 oz against 9.9 oz for the Gel-Cumulus 23 and 9.5 oz for the Gel-Cumulus 25, on a 24 mm heel and a $130 list price. Whether that is worth chasing depends on what the Gel-Cumulus 24 update actually did, which the section above works through.
- Did the Gel-Cumulus get taller between the Gel-Cumulus 23 and the Gel-Cumulus 25?
- Heel stack went 23 mm to 37.5 mm, by way of 24 mm on the Gel-Cumulus 24. Drop moved 10 mm to 8 mm, which is the change your calves and Achilles notice.
- Where does the Gel-Cumulus 25 sit in the Gel-Cumulus lineup now?
- Two versions on from the Gel-Cumulus 23, and already replaced itself: the Gel-Cumulus 26 arrived in 2024. If you are shopping old stock anyway, price the Gel-Cumulus 25 against it before deciding.
