Altra has been selling zero drop since 2011 without ever winning everyone over. The Timp 5 shifts things a little: it finally swaps the in-house rubber for Vibram Megagrip, sheds weight and keeps its rule-breaking DNA. RunMorph put under the microscope the version that finally delivers the grip the Timp line had been waiting for.

The Altra Timp 5 is a versatile zero drop trail shoe built for runnable paths and mid-distance trail, with a Vibram Megagrip outsole that finally fixes the line's biggest weakness. The cushioning is generous in volume but stays firm, and energy return lags behind, so it suits easy endurance miles better than all-out performance. It's aimed first at runners already converted to zero drop or ready to make a gradual transition, not at those chasing a lively ride.
Altra has built a loyal fan base around a simple promise: zero drop, a wide toe box and a more natural stride. The flip side has long been the in-house rubber, which often fell short on wet ground against the category's heavyweights. The Timp 5 changes that: it's the first Timp to get a Vibram Megagrip outsole, the market benchmark for grip on every surface. On paper, this is the kind of update that can move an entire line from "likable but could be better" to "seriously recommendable."
It joins an Altra lineup RunMorph has already covered well, alongside the Lone Peak 9+, lighter and more minimalist, and the Olympus, built for ultras. The Timp sits right in the middle: more cushioning volume than the Lone Peak, less bulk than the Olympus, designed for runnable to moderately technical trail over distances from 10 km up to the trail marathon.
RunMorph tip: if you've never run in zero drop, don't make the Timp 5 your first pair for a marathon goal. Switching to zero drop takes several weeks of short easy runs to prepare, or you'll load your Achilles tendons and calves in a way your body isn't used to yet.

The outsole switch isn't cosmetic. Independent lab measurements show just 0.9 mm of wear on the standardized test protocol, a result that puts the Timp 5 near the top of the 143 trail shoes compared on this criterion. In practice, the grip holds on wet rock and roots, two surfaces where the old Altra rubber showed its limits. The 3.0 mm lugs stay modest: perfect for runnable paths and non-technical singletrack, marginal in deep mud, where 4 to 5 mm lugs would do the job better.
RunMorph cross-checked the Timp 5's independent measurement sheet (full lab protocol: cushioning, energy return, stability, durability) against field reports published by Runnea and several other specialist French trail sources, to set the hard data against real-world use.
On cushioning, the independent measurements leave no doubt: heel shock absorption comes in at 115 SA, below the 124 SA average recorded across 114 trail shoes compared. The feel described in the reviews matches: cushioning that looks voluminous (28.6 mm of stack height) but leans firm rather than soft, in line with the "ground connection" spirit Altra claims. On energy return, the figure is even harsher: 51.8% against an average of 56.7%, which clearly places the Timp 5 among easy endurance shoes rather than propulsive ones. The French scores we consulted (Runnea: lightness 8/10, cushioning 8/10, response 8/10, stability 7/10) remain good in absolute terms but agree on a comfortable, reliable shoe rather than a lively one.
Stability, on the other hand, gets a thumbs-up across the board: torsional rigidity rated 4/5 in independent testing, paired with an "exceptionally stable" feel even for runners with mild pronation, a point field reports confirm without reservation. The wide fit also wins unanimous praise, especially for feet that struggle in the competition's narrow toe boxes, but one review flags a narrower heel width (82.7 mm against a 90.6 mm average), less suited to heavy heel landings.
| Altra Timp 5 | Hoka Speedgoat 7 | |
|---|---|---|
| Drop | 0 mm (zero drop) | 4 mm |
| Weight | 269 g measured | ~257 g depending on size |
| Outsole | Vibram Megagrip, 3.0 mm lugs | Vibram Megagrip, 5 mm lugs |
| Ideal terrain | Runnable to moderately technical | Moderately to very technical |
| Stride profile | Midfoot / forefoot, firm | Heel to midfoot, softer |
| Price | €155 | €165 |
Both shoes target the same versatile use, but with opposite philosophies. The Timp 5 imposes a more natural stride and a more direct ground feel, which calls for an adaptation phase if you don't already run in zero drop. The Speedgoat 7 is easier to get along with out of the box, with its classic 4 mm drop and deeper lugs that handle technical and muddy terrain better. The choice comes down less to pure performance than to your personal tolerance for zero drop.

The Timp 5 delivers on its promise: it's a comfortable, stable, versatile shoe that finally has the grip to match. But it remains a zero drop specialist's shoe, not a universal entry point. If your stride is already adapted, it ticks every box for a reliable long run pair on runnable to moderately technical paths.
The Altra Timp 5 fixes the line's biggest flaw with a Vibram Megagrip outsole that lives up to its promise in independent testing. It remains an easy endurance shoe, though, not a lively one: energy return and shock absorption both measure below their category average, and comfort and stability only partly make up for it. 8.2/10: a good versatile zero drop shoe for runners already converted, not a reason to change your running philosophy overnight.
