Refined, same shoe
THE SHORT ANSWER
Both are still stocked, so this is a real choice: the Timp 5 is the lighter shoe by 0.7 oz, and older models usually sell under list once a successor ships. The Timp 5 also lists $10 lower.

Every spec, side by side
| Spec | Timp 5 | Timp 6 |
|---|---|---|
| FIT AND WEIGHT | ||
| Weight | 9.5 oz | 10.2 oz |
| Both RunRepeat lab figures at a men's 9, so this 0.7 oz is measured on one scale. Ignore Altra's own pair, which reads 9.8 oz for the 5 and 11.45 oz for the 6: that 1.65 oz gap is a change in how Altra quotes weight, not a change in the shoe. Running Warehouse weighed the 6 at 9.9 oz. | ||
| Widths | D | D |
| Upper | Engineered mesh with structured midfoot overlays | Soft rolled mesh, 85 percent recycled PET, with fewer midfoot overlays and a semi-rigid toe cap |
| The reason the 6 exists. Barefoot Run Review's read on the 5 was too structured for wider, deeper feet and too rigid in the midfoot; its read on the 6 is fewer overlays in the midfoot, a more flexible upper, and a better balance between fit and feel. RunRepeat's calipers agree: toebox width 79.6 mm on the 5, 81.9 mm on the 6. | ||
| CUSHIONING GEOMETRY | ||
| Heel stack | 29 mm | 30 mm |
| Altra's own spec, and small enough to be a real change rather than a re-quote: RunRepeat's lab read 30.0 mm at the heel and 29.2 mm at the forefoot. Zero drop holds, as it has for every Timp. | ||
| Forefoot stack | 29 mm | 30 mm |
| Drop | 0 mm | 0 mm |
| MATERIALS | ||
| Midsole | Altra EGO MAX, updated formula | Altra EGO MAX, updated formula |
| VALUE | ||
| List price at launch | $155 | $165 |
| Up $10, and both RunRepeat and Believe in the Run flagged it. BITR graded the 6 a C on value and put it next to the $150 Saucony Peregrine 16. | ||
| OTHER CHANGES | ||
| Outsole | Vibram Megagrip | Vibram Megagrip, tread recut for more forefoot grip |
| Grippier, and enough lug that Section Hiker called the 6 a trail-only shoe where the 5 could handle the road section to the trailhead. | ||

Questions runners ask
- Which is lighter, the Altra Timp 5 or the Timp 6?
- The Altra Timp 5, by 0.7 oz in a men's US 9 (9.5 oz vs 10.2 oz).
- Did the price change between the Altra Timp 5 and the Timp 6?
- Yes. List price went up $10, from $155 to $165. Street prices differ: the older shoe usually sells under list once its successor ships.
- Do the Altra Timp 5 and Timp 6 come in the same widths?
- Yes. Both run in D for men's sizes, so a width that fit in the Timp 5 carries over to the Timp 6.
- How do the stack heights compare?
- 29 mm heel and 29 mm forefoot on the Altra Timp 5, against 30 mm and 30 mm on the Timp 6. That is 1 mm more under the heel and 1 mm more under the forefoot. See the stack height note in the table above: the published figures changed convention mid-lineage.
- Is the Timp 6 still the newest Timp?
- Yes. The Timp 6 is the current Altra Timp, listing at $165 at launch.
