Altra Olympus 275 HiLo Women's Trail Running Shoes

Max Cushion. Lightweight MATRYX® Upper. Built to Go Long.

The Altra Olympus 275 HiLo Women's takes the plush, protective platform of the Olympus family and gives it a lighter, more performance-focused edge for long-distance trail running and ultramarathons.

Built around Altra's updated EGO™ MAX midsole, the Olympus 275 HiLo delivers high cushioning for long days on the trail while maintaining Altra's signature 0mm drop and roomy FootShape™ fit. The updated EGO MAX foam is 15% lighter and 10% softer, helping create a smoother, more comfortable ride when the kilometres start adding up.

Where the 275 HiLo really stands apart is its premium MATRYX® one-piece woven upper. Lightweight, durable and supportive, MATRYX gives the shoe a more refined performance feel, while an integrated scree sleeve helps prevent trail debris from finding its way inside.

Underfoot, Vibram® Megagrip with TractionLug™ provides dependable grip across demanding trail terrain.

For ultra runners looking for the cushioning of an Olympus in a lighter package, the Olympus 275 HiLo Women's is built for serious distance.

Updated Altra EGO™ MAX Cushioning

Long-distance trail running demands cushioning that remains comfortable hour after hour.

The Olympus 275 HiLo features Altra's updated EGO™ MAX midsole, engineered to be 15% lighter and 10% softer than the previous version.

That means plenty of underfoot protection without making the shoe feel unnecessarily heavy.

With a substantial 33mm stack height, the Olympus 275 HiLo sits firmly in Altra's high-cushion trail category, making it particularly well suited to:

• Ultramarathons
• Long trail races
• High-volume trail training
• Long-distance hiking
• Fastpacking
• Long days on hard and rocky trails

When comfort becomes increasingly important as the hours accumulate, the Olympus platform is designed to keep protecting your feet.

0mm Drop – Balanced Cushioning from Heel to Toe

The Women's Olympus 275 HiLo features:

Heel Stack: 33mm
Forefoot Stack: 33mm
Heel-to-Toe Drop: 0mm

Altra's 0mm drop platform places your heel and forefoot at the same height from the ground, creating the balanced geometry the brand is known for.

Combined with the high stack, this gives you the unusual combination of maximum-style cushioning with zero-drop geometry.

If you're new to zero-drop running shoes, we recommend transitioning gradually—particularly when moving across from footwear with a significantly higher heel-to-toe drop.

MATRYX® Upper – Lightweight Performance Meets Durability

The upper is one of the defining features of the Olympus 275 HiLo.

Rather than using a conventional engineered mesh construction, Altra uses a premium one-piece MATRYX® woven upper.

MATRYX technology is designed to provide an excellent combination of:

• Lightweight performance
• Durability
• Structure
• Secure foot hold
• Breathability

For long-distance trail runners, this helps reduce unnecessary weight while still providing the security needed when moving over uneven terrain.

It also gives the Olympus 275 HiLo its distinctive premium, race-ready character.

Built-In Scree Sleeve

Tiny stones, sand and trail debris might seem insignificant at the start of a run.

After hours on the trail, they're anything but.

The Olympus 275 HiLo incorporates a built-in scree sleeve, providing additional coverage around the shoe opening to help prevent loose debris from getting inside.

It's a particularly useful addition for:

• Ultramarathons
• Loose gravel trails
• Rocky terrain
• Dry Australian trails
• Long-distance trail racing
• Fastpacking

Less stopping to empty your shoes means more time moving forward.

Vibram® Megagrip with TractionLug™

Underfoot, the Olympus 275 HiLo uses one of the most trusted names in trail traction: Vibram® Megagrip.

Megagrip is designed to provide dependable traction across both wet and dry trail surfaces, giving the Olympus the grip needed for changing terrain.

Altra pairs this with Vibram TractionLug™ technology, designed to enhance traction through the shape and geometry of the outsole lugs.

That combination gives the Olympus 275 HiLo the confidence to tackle:

• Rocky trails
• Loose gravel
• Hard-packed trails
• Technical singletrack
• Wet rock
• Steep climbs and descents
• Long-distance mountain terrain

It's a significant part of what makes the Olympus family such a strong option for long-distance trail running.

Roomy Altra FootShape™ Fit

Long-distance comfort isn't only about cushioning.

Fit matters just as much.

The Olympus 275 HiLo uses Altra's roomy FootShape™ philosophy, giving your toes space to spread naturally rather than squeezing the forefoot into a traditional tapered shoe shape.

That extra room can become increasingly valuable during ultras and long trail adventures, when feet naturally swell after hours of running.

The aim is simple:

Room for the toes. Security where you need it.

For runners who regularly experience forefoot pressure or simply prefer more natural toe space, it's one of the defining benefits of the Olympus platform.

Lightweight for a High-Cushion Trail Shoe

The Women's Olympus 275 HiLo weighs approximately:

249g – Women's US 8.5

That's particularly impressive considering the shoe's 33mm cushioning, Vibram Megagrip outsole and long-distance trail focus.

Reducing weight becomes increasingly meaningful when you're lifting your feet thousands of times over an ultra-distance event.

The combination of the MATRYX upper and updated EGO MAX foam helps the 275 HiLo deliver Olympus-level protection in a lighter package.

Why Choose the Altra Olympus 275 HiLo Women's?

Think of the Olympus 275 HiLo as a more performance-focused expression of what makes the Olympus platform so popular.

You still get the features long-distance runners value—high cushioning, zero-drop geometry, generous toe room and Vibram Megagrip traction—but the MATRYX upper and lighter updated EGO MAX foam help reduce weight.

Choose the Olympus 275 HiLo if you want:

• High cushioning for ultra-distance running
• A lightweight trail shoe despite generous cushioning
• Premium MATRYX upper construction
• Dependable Vibram Megagrip traction
• A roomy, foot-shaped forefoot
• Balanced 0mm-drop geometry
• Integrated protection against trail debris
• A trail shoe designed for long races and big adventures

It's particularly appealing to the runner who loves the protective feel of the Olympus but wants something lighter, sleeker and more performance-oriented.

Olympus 275 HiLo vs Olympus 7

Both shoes share the Olympus DNA, but they offer slightly different experiences.

The Olympus 7 focuses heavily on plush, everyday long-distance trail comfort and durability.

The Olympus 275 HiLo adds a premium MATRYX upper, built-in scree sleeve and significantly lighter construction, making it especially interesting for runners looking towards racing, ultras and faster long-distance adventures.

At approximately 249g for the Women's 275 HiLo versus 274g for the Women's Olympus 7, the 275 HiLo saves around 25g per shoe while retaining the familiar high-cushion Olympus platform.
