Can I go straight from the Altra Lone Peak 7 to the Lone Peak 9 and skip the Lone Peak 8?

Yes. Going Lone Peak 7 to Lone Peak 9 skips the Lone Peak 8, and neither update changed the ride, so you land on the same shoe two refinements later. The midsole is the one real difference: Altra EGO to Updated Altra EGO.

How much did the weight change across these two updates?

0.6 oz off in total, 11 oz to 10.4 oz in a men's US 9. The Lone Peak 8 took it to 10.7 oz first.

Is the Lone Peak 8 the better buy than either of these?

On paper it splits them: 10.7 oz against 11 oz for the Lone Peak 7 and 10.4 oz for the Lone Peak 9, on a 25 mm heel and a $140 list price. Whether that is worth chasing depends on what the Lone Peak 8 update actually did, which the section above works through.

Where does the Lone Peak 9 sit in the Lone Peak lineup now?

It is the current model, two versions on from the Lone Peak 7 and the newest one you can buy at full retail.

THE SHORT ANSWER

Two updates and 2 years separate the Altra Lone Peak 7 from the Lone Peak 9. Net change: 0.6 oz lighter, a new midsole, $10 less at list. Neither update in between changed what the Lone Peak is, so this is the same shoe refined twice rather than a new one.

Or buy the Lone Peak 8 instead?

The Lone Peak 8 is the value play if you find it discounted. It carries most of what the Lone Peak 9 added while selling as an older model, and moving one version at a time is the smaller adjustment.
