Can I go straight from the Asics Gel-Nimbus 23 to the Gel-Nimbus 25 and skip the Gel-Nimbus 24?

Yes, but going Gel-Nimbus 23 to Gel-Nimbus 25 means taking one change in a single step: the Gel-Nimbus 25 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?

0.7 oz off in total, 10.9 oz to 10.2 oz in a men's US 9. The Gel-Nimbus 24 took it to 10.2 oz first.

Is the Gel-Nimbus 24 the better buy than either of these?

On paper it splits them: 10.2 oz against 10.9 oz for the Gel-Nimbus 23 and 10.2 oz for the Gel-Nimbus 25, on a 26 mm heel and a $160 list price. Availability decides it: Amazon's Gel-Nimbus 24 stock is gone in both men's and women's sizes, so it is not a live option.

Did the Gel-Nimbus get taller between the Gel-Nimbus 23 and the Gel-Nimbus 25?

Heel stack went 25 mm to 41.5 mm, by way of 26 mm on the Gel-Nimbus 24. Drop moved 10 mm to 8 mm, which is the change your calves and Achilles notice.

Where does the Gel-Nimbus 25 sit in the Gel-Nimbus lineup now?

Two versions on from the Gel-Nimbus 23, and already replaced itself: the Gel-Nimbus 26 arrived in 2024. If you are shopping old stock anyway, price the Gel-Nimbus 25 against it before deciding.
