Add the fifth version of the Altra Olympus to your running shoe rotation if you want a protective and comfy shoe for: 

  • long, slow runs on the trails 
  • backpacking and hiking

Who should NOT buy it

For its hefty £170 price, the Olympus 5 has some serious durability issues. If you want a shoe that will last you a long time and is less expensive, we are of the opinion that the Altra Lone Peak 6 will fit you just right. And if you don't want any of that lace bite, you're better off with the Altra Superior 6.

Altra Olympus 5 vs. 4

The newer iteration of the Olympus introduces the following updates:

  • roomier toe box
  • more padded heel for better lockdown 
  • pull tab added for easy on and off
  • snugger, more secure fit

You'll forget about the miles 

And that's because this trail shoe is super comfortable.

Based on our durometer measurements, the foam on the Altra Olympus 5 is moderately soft. It is 20% softer than the average of trail running shoes, to be specific.

Disclaimer: We take the measurement 5 times to ensure accuracy. The photo shows one of them.

When exposed to cold temperatures, the shoe's cushioning firms up a little more than other foam types. It becomes 36.3% more rigid.

There's nothing quite like the Olympus 5's protection

Apart from its comfy and well-cushioned ride, the Altra Olympus 5 also has more beef to it. So much so that you don't have to worry about the rocks and debris beneath you.

This Altra shoe has an average stack height in the heel (33 mm) compared to other running shoes but is significantly thicker in the forefoot: 31 mm over the average 24 mm.

Disclaimer: We include the insole thickness in our stack measurements. The insole in the Altra Olympus 5 is 5.3 mm, which is 0.8 mm thicker than the average.

altra-olympus-5-insole

Despite the brand's statement that all of its shoes have a 0-mm drop, the Olympus 5 comes with a 2-mm heel-to-toe differential, based on our measurements: 33 mm (heel) - 31 mm (forefoot) = 2 mm.

Great airflow for a trail runner

You can see how easily the smoke comes through the shoe's upper in multiple places, not just the toebox.

We also checked the upper fabric transparency with a light test.

The Olympus 5 adds some flavour to your run

Why? Because it has an additional kick and energy return. Upon landing, the shoe feels like an armchair but on the take-off, it delivers a truly impressive amount of energy return.

Flexibility is sacrificed though

With all that amount of cushioning, we expected that the Altra Olympus 5 would be far from a minimalist shoe in terms of flexibility.

But the shoe is full of surprises! And our force gauge test showed that the Olympus requires the same amount of force to bend to a 90-degree angle as the average.

Disclaimer: The video shows 1 out of 5 takes that we make with the flexibility measurement tool to ensure accuracy.

We also gave the shoe's torsional flexibility 3 out of 5 (5 being the stiffest) in our subjective assessment.

Don't worry about your feet slipping

We have thoroughly enjoyed the stable and planted steps ensured by the shoe. Its base is very wide, so you don't have to worry about missteps.

The shoe's forefoot width (110.8 mm) is average compared to other running shoes (111.7 mm). But what makes it impressive is the heel width (100.2 mm) which is 11.5(!)mm wider than the average.

altra-olympus-5-heel-width

On top of this, the shoe's midsole also has raised sidewalls.

altra-olympus-5-raised-sidewalls-stability

This is a huge step for the Olympus, especially because the fourth version lacked this kind of support.

The heel hold deserves applause

In version 4 of the Altra Olympus, the heel lockdown was also quite disappointing. But this issue has been addressed in the newer iteration.

With the more generously padded heel counter, we experienced zero slippage!

Altra nails the fit in the Olympus 5

The Altra Olympus 5's fit is fantastic!

The midfoot and heel areas are very snug-fitting whereas the toebox offers an enormous amount of space.

The fully gusseted tongue also contributes to the locked-in feel.

altra-olympus-5-gusseted-tongue

The toebox is a true Altra

This means that it offers plenty of toe space. Black toenails are a thing of the past with the Olympus 5.

The forefoot in this Altra shoe is indeed much wider than most running shoes. We measured its widest part at 103.4 mm, which is nearly 5 mm wider than the average. Not to mention the wide and squared shape of the toebox!

Reflective elements keep you visible

The laces and lines around the collar are made reflective so that you can run more confidently in low-light conditions.

It's easy to put on and take off

Thanks to the added pull tab, it's now easy to slide the Olympus 5 on and off.

altra-olympus-5-pull-tab

Ugh, that annoying lace bite

Unfortunately, the laces kept cutting into our skin in this Altra shoe.

This is surprising because we actually measured the tongue thickness to be 7.4 mm. This is thicker than the average 5.8 mm.

altra-olympus-5-tongue-thickness

Perhaps this is because the padding doesn't extend all the way up the tongue.

altra-olympus-5-tongue

This is £180? 

Because its durability says otherwise. The outsole, although Vibram, sucks because it doesn't hold up well. It started peeling away from the sole after only a few runs!

altra-olympus-5-outsole-thickness

We also discovered that the shoe has thinner-than-average rubber layers and lugs. The Vibram outsole is 2.8 mm, 0.7 mm thinner than the average. The lugs (3.0 mm) are also a bit smaller than the average (3.5 mm). That means it takes less abrasion to wear through the shoe's outsole.

At least it bites

On the bright side, the outsole does stick to the ground. It performs and grips well.

Whether on wet or dry roads or wet and dry trails, the Altra Olympus 5 clings.

Convenient gaitor attachment

There is a Velcro piece at the back which is very handy for fixing your gaitor.
