Altra Olympus 275 Hiit Low Review: A Zero-Drop Trail Shoe That Wins You Over

Introduction

The Altra Olympus 275 Hiit Low is a zero-drop trail shoe built for technical terrain, and it arrives with a few meaningful updates under the hood. The midsole is an updated Altra Ego Max foam that is 15% lighter and 10% softer than the previous version, aiming to keep longer sessions comfortable. On paper it costs £175 or $200, weighs 278 g (9.8 oz) for men in a size 8, and keeps the 0 mm drop Altra is known for. After extended testing, this one earned genuine enthusiasm rather than polite respect.

Specs at a Glance

• Price: £175 / $200
• Weight: 278 g / 9.8 oz (men’s size 8)
• Drop: 0 mm
• Midsole: updated Altra Ego Max (15% lighter, 10% softer than before)
• Outsole: Vibram Mega Grip with a traction lug design

Fit and Comfort

Fit is one of Altra’s biggest selling points, and this shoe is no exception. The toe box is genuinely wide, with plenty of wiggle room in the forefoot and around the big toe. The midfoot is forgiving too, which makes this a very sensible choice if you have wider feet.

Despite the roominess, the upper still delivers a solid lockdown, which matters when you are moving quickly down technical descents. There is a soft collar around the ankle that helps keep debris out, and a fairly rigid but comfortable tongue. The recommendation is simple: stay true to your size, because the fit is dialed in.

The upper uses Altra’s Matrix one-piece woven construction carried over from the original Olympus 275, built to hold up under repeated technical use, with a squeeze sleeve woven straight into the upper to keep debris out. In practice it feels breathable, comfortable, and secure all at once.

Ride and Outsole Performance

This is where the shoe genuinely surprised. Zero-drop shoes do not work for everyone, and previous experience with Altra’s foams has often been mixed. The updated Ego Max midsole changes that. It is soft but stable, with a really wide base lending itself nicely to a natural, rolling feel underfoot. It does not deliver loads of bounce, but it delivers comfort, and it feels easy to pick up the pace on harder ground.

The Vibram Mega Grip traction lug outsole is a highlight. The lugs are not particularly large, but the design is excellent: it grips well across climbs and descents, adapts as conditions change underfoot, and does not get in the way on hard ground or road the way bigger-lugged trail shoes can. It rides smoothly on tarmac for stretches and still protects your feet from pointed rocks. One caveat: very wet mud was not tested during this period, so extreme mud performance remains an open question.

Long Run and Versatility

Testing runs varied from about 10 to 25 km across mixed terrain: climbs, rocky sections, muddy bits, fields, and plenty of road linking it all together. The shoe handled all of it comfortably. Short easy runs feel padded and pleasant, while long runs are clearly where this shoe is aimed, returning a lot of comfort from the Ego Max foam over long, slow, consistent-pace efforts.

If you are considering ultra training across varied terrain, this is a very sensible candidate precisely because it is so comfortable to run in for extended periods. It is not the fastest shoe around and is not designed to be; it is designed for comfort.

Who Should Buy It

If you are already an Altra fan, you will likely enjoy this: the wide toe box, the splayed-toes feel, and now a foam that finally feels like it works with the shoe’s wide base and zero-drop geometry. If you are not an Altra fan, this could be the gateway shoe. For many testers who have struggled with previous Altra models, this is the first one that genuinely turned their head.

Buying Advice

At £175 or $200, this is a pricey trail shoe, but the extra cost feels justified. There is simply more to this shoe than in many cheaper options: the foam quality, the outsole design, the woven upper, and the overall balance of the ride all add up. The main trade-offs are the price, the zero-drop geometry that will not suit everyone, and an outsole that is excellent on most terrain but unproven in really wet mud.

It is worth thinking about how you run, too. If your week is mostly short, fast efforts, other shoes may serve you better. If your happy place is long, comfortable miles over mixed ground, this shoe makes a compelling case.

Conclusion

The Altra Olympus 275 Hiit Low is a big win: a comfortable, balanced, surprisingly easy-to-run zero-drop trail shoe with a great foam, an excellent Vibram outsole, and the roomy fit Altra is famous for. It is not built for speed, but for long, comfortable, consistent trail running it is hard to beat, and it is the kind of shoe that keeps getting chosen even when it is not being tested.
