Can I go straight from the Asics Gel-Cumulus 25 to the Gel-Cumulus 27 and skip the Gel-Cumulus 26?

Yes, but going Gel-Cumulus 25 to Gel-Cumulus 27 means taking one change in a single step: the Gel-Cumulus 26 is where the ride moved. Drop holds at 8 mm, so the difference is foam and fit rather than geometry: FF Blast Plus with a re-engineered PureGEL heel insert to FF Blast Plus Eco over a firmer EVA carrier, with a PureGEL heel insert.

How much did the weight change across these two updates?

0.2 oz off in total, 9.5 oz to 9.3 oz in a men's US 9. The Gel-Cumulus 26 took it to 9 oz first.

Is the Gel-Cumulus 26 the better buy than either of these?

On paper it splits them: 9 oz against 9.5 oz for the Gel-Cumulus 25 and 9.3 oz for the Gel-Cumulus 27, on a 38.5 mm heel and a $140 list price. Whether that is worth chasing depends on what the Gel-Cumulus 26 update actually did, which the section above works through.

Did the Gel-Cumulus get taller between the Gel-Cumulus 25 and the Gel-Cumulus 27?

Heel stack went 37.5 mm to 38.5 mm, by way of 38.5 mm on the Gel-Cumulus 26. Drop held at 8 mm throughout, so the extra foam sits under both ends.

Where does the Gel-Cumulus 27 sit in the Gel-Cumulus lineup now?

Two versions on from the Gel-Cumulus 25, and already replaced itself: the Gel-Cumulus 28 arrived in 2026. If you are shopping old stock anyway, price the Gel-Cumulus 27 against it before deciding.

THE SHORT ANSWER

Two updates and 2 years separate the Asics Gel-Cumulus 25 from the Gel-Cumulus 27. Net change: 0.2 oz lighter, 1 mm more heel stack, a new midsole. The Gel-Cumulus 26 is where the character changed, and that is the update Gel-Cumulus 25 owners notice first.

Or buy the Gel-Cumulus 26 instead?

The Gel-Cumulus 26 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.
