Can I go straight from the Brooks Ghost 15 to the Ghost 17 and skip the Ghost 16?

Yes, but going Ghost 15 to Ghost 17 means taking one change in a single step: the Ghost 17 is where the ride moved. The drop also goes 12 mm to 10 mm across the jump, so give it a week of easy running.

How much did the weight change across these two updates?

0.4 oz on in total, 9.8 oz to 10.2 oz in a men's US 9. Almost all of it came in the second update; the Ghost 16 weighed 9.8 oz.

Is the Ghost 16 the better buy than either of these?

On paper it splits them: 9.8 oz against 9.8 oz for the Ghost 15 and 10.2 oz for the Ghost 17, on a 35.5 mm heel and a $140 list price. Whether that is worth chasing depends on what the Ghost 16 update actually did, which the section above works through.

Did the Ghost get taller between the Ghost 15 and the Ghost 17?

Heel stack went 35 mm to 36 mm, by way of 35.5 mm on the Ghost 16. Drop moved 12 mm to 10 mm, which is the change your calves and Achilles notice.

Where does the Ghost 17 sit in the Ghost lineup now?

Two versions on from the Ghost 15, and already replaced itself: the Ghost 18 arrived in 2026. If you are shopping old stock anyway, price the Ghost 17 against it before deciding.

Two updates and 3 years separate the Brooks Ghost 15 from the Ghost 17. Net change: 0.4 oz heavier, 1 mm more heel stack, a drop change from 12 mm to 10 mm, a new midsole, $10 more at list. The Ghost 17 is where the character changed, and that is the update Ghost 15 owners notice first.

Or buy the Ghost 16 instead?

The Ghost 16 is the value play if you find it discounted. It carries most of what the Ghost 17 added while selling as an older model, and moving one version at a time is the smaller adjustment.
