Which is lighter, the Brooks Adrenaline GTS 23 or the Adrenaline GTS 24?

Neither by a meaningful margin. Both weigh about 10.1 oz in a men's US 9.

Do the Brooks Adrenaline GTS 23 and Adrenaline GTS 24 come in the same widths?

Yes. Both run in B, D, 2E, 4E for men's sizes, so a width that fit in the Adrenaline GTS 23 carries over to the Adrenaline GTS 24.

How do the stack heights compare?

36 mm heel and 24 mm forefoot on the Brooks Adrenaline GTS 23, against 39 mm and 27 mm on the Adrenaline GTS 24. That is 3 mm more under the heel and 3 mm more under the forefoot. See the stack height note in the table above: the published figures changed convention mid-lineage.

Is the Adrenaline GTS 24 still the newest Adrenaline GTS?

No. The Adrenaline GTS 25 replaced it in 2025, so the Adrenaline GTS 24 now sells as an older model and usually below its $140 list price.
