Refined, same shoe

Both are still stocked, so this is a real choice: the Lone Peak 9 is the lighter shoe by 0.3 oz, and older models usually sell under list once a successor ships.

Every spec, side by side
| Spec | Lone Peak 8 | Lone Peak 9 |
|---|---|---|
| FIT AND WEIGHT | ||
| Weight | 10.7 oz | 10.4 oz |
| Widths | D, 2E | D, 2E |
| Upper | Ripstop nylon with no-sew overlays | Recycled ripstop mesh with no-sew overlays |
| The toe rubber the 8 took away comes back, on the inside edge and over the top. iRunFar called the upper more bomber than before. | ||
| CUSHIONING GEOMETRY | ||
| Heel stack | 25 mm | 25 mm |
| Forefoot stack | 25 mm | 25 mm |
| Drop | 0 mm | 0 mm |
| MATERIALS | ||
| Midsole | Altra EGO | Updated Altra EGO |
| Lighter, and stiffer underfoot. Owners describe the 9 as stiff as wood out of the box, which eases but does not disappear. | ||
| Plate | Embedded full-length TPU StoneGuard | Embedded full-length TPU StoneGuard |
| VALUE | ||
| List price at launch | $140 | $140 |
| OTHER CHANGES | ||
| Outsole | MaxTrac, 3.0 mm lugs | MaxTrac with more coverage, 3.8 mm lugs and a flared heel |
| The headline change and the one testers noticed first. Switchback Travel said the rubber held up considerably better than on the 5, 6, 7 and 8. Altra also stopped using the TrailClaw name here. | ||
| Outsole option | MaxTrac only | MaxTrac, or Vibram Megagrip on the 9+ |
| Two months after the 9, Altra released the Lone Peak 9+: the same shoe with the Vibram outsole runners had been asking for since the 6, at $155 rising to $160. It is a parallel model rather than a new version, so it has no record here. Switchback Travel put the obvious objection plainly, that it is a bummer to pay more for the Vibram outsole. | ||
