Can I go straight from the Brooks Cascadia 16 to the Cascadia 18 and skip the Cascadia 17?

Yes. Going Cascadia 16 to Cascadia 18 skips the Cascadia 17, and neither update changed the ride, so you land on the same shoe two refinements later. Even the midsole carried over as DNA Loft v2.

How much did the weight change across these two updates?

0.4 oz on in total, 10.5 oz to 10.9 oz in a men's US 9. The Cascadia 17 took it to 11.3 oz first.

Is the Cascadia 17 the better buy than either of these?

On paper it splits them: 11.3 oz against 10.5 oz for the Cascadia 16 and 10.9 oz for the Cascadia 18, on a 33 mm heel and a $140 list price. Whether that is worth chasing depends on what the Cascadia 17 update actually did, which the section above works through.

Where does the Cascadia 18 sit in the Cascadia lineup now?

Two versions on from the Cascadia 16, and already replaced itself: the Cascadia 19 arrived in 2025. If you are shopping old stock anyway, price the Cascadia 18 against it before deciding.

THE SHORT ANSWER

Two updates and 3 years separate the Brooks Cascadia 16 from the Cascadia 18. Net change: 0.4 oz heavier, $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 17 instead?

The Cascadia 17 is the value play if you find it discounted. It carries most of what the Cascadia 18 added while selling as an older model, and moving one version at a time is the smaller adjustment.
