Can I go straight from the Brooks Cascadia 17 to the Cascadia 19 and skip the Cascadia 18?

Yes. Going Cascadia 17 to Cascadia 19 skips the Cascadia 18, and neither update changed the ride, so you land on the same shoe two refinements later. The midsole is the one real difference: DNA Loft v2 to DNA Loft v3, supercritical.

How much did the weight change across these two updates?

0.5 oz off in total, 11.3 oz to 10.8 oz in a men's US 9. The Cascadia 18 took it to 10.9 oz first.

Is the Cascadia 18 the better buy than either of these?

On paper it splits them: 10.9 oz against 11.3 oz for the Cascadia 17 and 10.8 oz for the Cascadia 19, on a 33 mm heel and a $140 list price. Whether that is worth chasing depends on what the Cascadia 18 update actually did, which the section above works through.

Did the Cascadia get taller between the Cascadia 17 and the Cascadia 19?

Heel stack went 33 mm to 35 mm, by way of 33 mm on the Cascadia 18. Drop moved 8 mm to 6 mm, which is the change your calves and Achilles notice.

Where does the Cascadia 19 sit in the Cascadia lineup now?

Two versions on from the Cascadia 17, and already replaced itself: the Cascadia 20 arrived in 2026. If you are shopping old stock anyway, price the Cascadia 19 against it before deciding.

THE SHORT ANSWER

Two updates and 2 years separate the Brooks Cascadia 17 from the Cascadia 19. Net change: 0.5 oz lighter, 2 mm more heel stack, a drop change from 8 mm to 6 mm, a new midsole, $10 more at list. Neither update in between changed what the Cascadia is, so this is the same shoe refined twice rather than a new one.

Or buy the Cascadia 18 instead?

The Cascadia 18 is the value play if you find it discounted. It carries most of what the Cascadia 19 added while selling as an older model, and moving one version at a time is the smaller adjustment.
