Every spec, side by side
| Spec | Lone Peak 5 | Lone Peak 6 |
|---|---|---|
| FIT AND WEIGHT | ||
| Weight | 10.6 oz | 9.7 oz |
| Close to an ounce a shoe, almost all of it from deleting the stitched overlays. Altra publishes Lone Peak weights at a men's 10.5, so its own figures read heavier than these; both numbers here are men's 9. | ||
| Widths | D, 2E | D, 2E |
| Upper | Engineered mesh with stitched overlays and drain perforations | Engineered mesh with bonded TPU overlays and laser-cut drain holes |
| Lighter, and the reason thru-hikers name the 6 as the year their shoes fell apart. The drain holes were cut too large. One hiker reported watching several pairs enter the Hundred Mile Wilderness new and come out in shreds, and a reviewer with more than 10,000 Lone Peak miles went through three pairs in 800. | ||

| Forefoot stack | 25 mm | 25 mm |
| Drop | 0 mm | 0 mm |
| MATERIALS | ||
| Midsole | Altra EGO | Altra EGO |
| Plate | Embedded full-length TPU StoneGuard | Embedded full-length TPU StoneGuard |
| VALUE | ||
| List price at launch | $130 | $140 |
| OTHER CHANGES | ||
| Fit | Runs long, loose through the midfoot | Runs about half a size shorter, locked through the midfoot |
| iRunFar found a men's 8.5 in the 5 fit like a 9, and the 6 corrected it. Longtime Altra buyers called that a relief. Anyone who had sized down to cope with the 5 had to size back up. | ||
| Outsole | MaxTrac with TrailClaw | MaxTrac with TrailClaw, carried over |
| The one thing the 6 did not touch. iRunFar described it as the exact same look and feel as the 5, and owners reported the tread wearing down well before the rest of the shoe. | ||
