Which is lighter, the Nike Structure 24 or the Structure 25?

The Structure 25, by 0.3 oz in a men's US 9 (10.7 oz vs 11 oz).

Did the price change between the Nike Structure 24 and the Structure 25?

Yes. List price went up $20, from $120 to $140. Street prices differ: the older shoe usually sells under list once its successor ships.

Do the Nike Structure 24 and Structure 25 come in the same widths?

Yes. Both run in D, 2E, 4E for men's sizes, so a width that fit in the Structure 24 carries over to the Structure 25.

How do the stack heights compare?

22 mm heel and 14 mm forefoot on the Nike Structure 24, against 37 mm and 27 mm on the Structure 25. That is 15 mm more under the heel and 13 mm more under the forefoot. See the stack height note in the table above: the published figures changed convention mid-lineage.

Is the Structure 25 still the newest Structure?

No. The Structure 26 replaced it in 2025, so the Structure 25 now sells as an older model and usually below its $140 list price.

Whichever your size still exists in. The Structure 24 is discontinued at retail, so remaining pairs sell against a thinning size run, while the Structure 25 has a full one. The Structure 24 also lists $20 lower.
