Can I go straight from the Nike Structure 23 to the Structure 25 and skip the Structure 24?

Yes, but going Structure 23 to Structure 25 means taking one change in a single step: the Structure 25 is where the ride moved. The drop also goes 8 mm to 10 mm across the jump, so give it a week of easy running.

How much did the weight change across these two updates?

0.5 oz on in total, 10.2 oz to 10.7 oz in a men's US 9. The Structure 24 took it to 11 oz first.

Is the Structure 24 the better buy than either of these?

On paper it splits them: 11 oz against 10.2 oz for the Structure 23 and 10.7 oz for the Structure 25, on a 22 mm heel and a $120 list price. Whether that is worth chasing depends on what the Structure 24 update actually did, which the section above works through.

Did the Structure get taller between the Structure 23 and the Structure 25?

Heel stack went 22 mm to 37 mm, by way of 22 mm on the Structure 24. Drop moved 8 mm to 10 mm, which is the change your calves and Achilles notice.

Where does the Structure 25 sit in the Structure lineup now?

Two versions on from the Structure 23, and already replaced itself: the Structure 26 arrived in 2025. If you are shopping old stock anyway, price the Structure 25 against it before deciding.

THE SHORT ANSWER

Two updates and 3 years separate the Nike Structure 23 from the Structure 25. Net change: 0.5 oz heavier, 15 mm more heel stack, a drop change from 8 mm to 10 mm, a new midsole, $20 more at list. The Structure 25 is where the character changed, and that is the update Structure 23 owners notice first.

Or buy the Structure 24 instead?

The Structure 24 is the value play if you find it discounted. It carries most of what the Structure 25 added while selling as an older model, and moving one version at a time is the smaller adjustment.
