Can I go straight from the Brooks Adrenaline GTS 21 to the Adrenaline GTS 23 and skip the Adrenaline GTS 22?

Yes. Going Adrenaline GTS 21 to Adrenaline GTS 23 skips the Adrenaline GTS 22, and neither update changed the ride, so you land on the same shoe two refinements later. The midsole is the one real difference: Full-length DNA Loft over a BioMoGo DNA base to DNA Loft v2 foam.

How much did the weight change across these two updates?

0.3 oz off in total, 10.4 oz to 10.1 oz in a men's US 9. The Adrenaline GTS 22 took it to 10.2 oz first.

Is the Adrenaline GTS 22 the better buy than either of these?

On paper it splits them: 10.2 oz against 10.4 oz for the Adrenaline GTS 21 and 10.1 oz for the Adrenaline GTS 23, on a 36 mm heel and a $140 list price. Whether that is worth chasing depends on what the Adrenaline GTS 22 update actually did, which the section above works through.

Where does the Adrenaline GTS 23 sit in the Adrenaline GTS lineup now?

Two versions on from the Adrenaline GTS 21, and already replaced itself: the Adrenaline GTS 24 arrived in 2024. If you are shopping old stock anyway, price the Adrenaline GTS 23 against it before deciding.

THE SHORT ANSWER

Two updates and 3 years separate the Brooks Adrenaline GTS 21 from the Adrenaline GTS 23. Net change: 0.3 oz lighter, a new midsole, $10 more at list. Neither update in between changed what the Adrenaline GTS is, so this is the same shoe refined twice rather than a new one.

Or buy the Adrenaline GTS 22 instead?

The Adrenaline GTS 22 is the value play if you find it discounted. It carries most of what the Adrenaline GTS 23 added while selling as an older model, and moving one version at a time is the smaller adjustment.
