Can I go straight from the Saucony Guide 15 to the Guide 17 and skip the Guide 16?

Yes, but going Guide 15 to Guide 17 means taking one change in a single step: the Guide 17 is where the ride moved. The drop also goes 8 mm to 6 mm across the jump, so give it a week of easy running.

How much did the weight change across these two updates?

It nets out. The Guide 15 and the Guide 17 both weigh about 9.5 oz in a men's US 9, though the Guide 16 sat at 9.5 oz in between.

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

On paper it splits them: 9.5 oz against 9.5 oz for the Guide 15 and 9.4 oz for the Guide 17, on a 35 mm heel and a $140 list price. Whether that is worth chasing depends on what the Guide 16 update actually did, which the section above works through.

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

Heel stack went 35 mm to 35 mm, by way of 35 mm on the Guide 16. Drop moved 8 mm to 6 mm, which is the change your calves and Achilles notice.

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

Two versions on from the Guide 15, and already replaced itself: the Guide 18 arrived in 2025. If you are shopping old stock anyway, price the Guide 17 against it before deciding.

THE SHORT ANSWER

Two updates and 2 years separate the Saucony Guide 15 from the Guide 17. Net change: a drop change from 8 mm to 6 mm, a new midsole. The Guide 17 is where the character changed, and that is the update Guide 15 owners notice first.

Or buy the Guide 16 instead?

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