Our Verdict: 7.8/10
The Altra Olympus 6 is a maximalist trail running shoe built for ultra-distance adventures and long hiking days. With its signature zero-drop platform and foot-shaped toe box, this shoe delivers superior comfort for extended trail sessions.
While it’s heavier than most trail runners, the trade-off comes with superior cushioning, rock-solid stability, and legendary Vibram grip that keeps you upright on challenging terrain.
After testing the Olympus 6 across varied trail conditions, I found it excels as a protective, confidence-inspiring shoe for runners who prioritize comfort over speed.
The 33mm stack height provides serious underfoot protection, while the wide platform design creates remarkable stability even on technical trails.
However, the significant weight penalty and basic midsole foam technology hold it back from being truly excellent at this price point.
Altra Olympus 6 Key Features
- Traction: Vibram Megagrip outsole with updated lug pattern delivers premium grip on wet and dry surfaces, making you feel glued to the trail even on technical terrain
- Comfort: 33mm zero-drop stack height provides maximum cushioning for ultra-distance adventures, though the basic EVA foam lacks energy return compared to modern alternatives
- Breathability: Improved engineered mesh upper offers better ventilation than previous models, but still struggles in hot weather due to extensive overlay coverage
- Weight: At 12.5 oz (354g) for men’s size 9, this is significantly heavier than most trail runners, impacting climbing performance and overall agility
- Waterproofing: Standard version is non-waterproof with good drainage; GTX variants available for wet conditions but add weight and reduce breathability
- Support: Zero-drop platform with ultra-wide base creates remarkable stability and natural foot positioning, perfect for runners transitioning from traditional shoes
- Fit and Sizing: Original FootShape design provides generous toe box space but runs small in length; most runners need to size up half a size for proper fit
- Durability: Reinforced construction with 360-degree overlays addresses the previous model’s durability issues, built to withstand hundreds of trail miles

CONS
Altra Olympus 6 Pricing
The Altra Olympus 6 retails for $175, positioning it in the premium trail running shoe category. While this isn’t the most expensive trail shoe available, it’s certainly not budget-friendly either.
When you compare it to other maximalist trail options, the pricing becomes more questionable given the basic midsole technology.
| Altra Olympus 6 | HOKA Stinson 7 | New Balance More Trail v3 | Brooks Caldera 7 | |
|---|---|---|---|---|
| Price | $175 | $170 | $160 | $150 |
| Weight (Men’s 9) | 12.5 oz | 12.1 oz | 12.8 oz | 10.9 oz |
| Stack Height | 33mm/33mm | 37mm/32mm | 36mm/32mm | 30mm/26mm |
| Drop | 0mm | 5mm | 4mm | 4mm |
**As of June 2025. Pricing may vary by retailer.
The Olympus 6 sits right in the middle price-wise, but when you factor in the dated midsole foam technology, it feels overpriced. Brands like Brooks and New Balance offer more advanced foam compounds at lower price points.
That said, if you specifically need the zero-drop platform and foot-shaped toe box that Altra provides, you’re paying for specialized features that other brands simply don’t offer.
One positive aspect is that you can often find the Olympus 6 on sale at major retailers like REI and Running Warehouse, especially as newer models are released.
The shoe also qualifies for REI’s generous return policy, giving you ample time to test whether it works for your feet and running style.
Verdict: 6/10
Altra Olympus 6 Initial Impression
Getting into the Olympus 6 reveals both its strengths and quirks. The first thing you notice is the substantial build quality – this shoe feels like it could survive an apocalypse.
The engineered mesh upper has a premium feel, and the reinforced overlays suggest this shoe means business for serious trail adventures.
However, the fit presents some challenges. The shoe runs slightly small in length, so many runners need to size up by half a size.
The signature FootShape toe box provides incredible room for your toes to spread naturally, but the midfoot area can feel restrictive due to internal support overlays. This creates an odd sensation where your toes have tons of space while your midfoot feels locked down.
The Achilles pillow, while intended to improve comfort, creates fit issues for many runners. Some testers reported it makes the heel feel shallow and unstable, leading to concerns about the foot sliding out during runs.
Others experienced blisters and hot spots where the pillow rubbed against their ankle bone.
| Fit Aspect | Rating | Notes |
|---|---|---|
| Length | Runs Small | Size up 0.5 for most runners |
| Width | Very Wide | Original FootShape fit accommodates wide feet |
| Toe Box | Excellent | Generous space for natural toe splay |
| Midfoot | Restrictive | Overlays can feel tight on wider feet |
| Heel | Mixed | Achilles pillow causes issues for some |
The lacing system works well once you dial in the fit. The thick, hiking boot-style laces feel durable but add unnecessary weight.
A heel-lock lacing technique helps address some of the heel fit concerns, though you need to be careful with the shortened tongue design that doesn’t extend as high as previous models.
Verdict: 6.5/10
Altra Olympus 6 Traction
The Vibram Megagrip outsole is where the Olympus 6 truly excels.
From a user perspective, this sticky rubber compound makes you feel practically glued to the trail, whether you’re navigating wet granite slabs or loose scree fields.
The updated lug pattern features more aggressive treads in the forefoot that bite into climbs, while the heel maintains proven split-channel design for downhill stability.
During extensive testing across varied terrain, the traction never left me questioning my footing. Even on steep, wet rock faces where other shoes would slip, the Megagrip held firm.
The 5mm lug depth strikes the perfect balance – deep enough for serious grip without feeling clunky on harder surfaces.
| Trail Surface | Altra Olympus 6 | HOKA Stinson 7 | New Balance More Trail v3 | Brooks Caldera 7 |
|---|---|---|---|---|
| Dry Rock | Excellent | Very Good | Good | Very Good |
| Wet Rock | Excellent | Good | Fair | Good |
| Mud | Very Good | Good | Very Good | Very Good |
| Loose Dirt | Excellent | Very Good | Good | Very Good |
| Hard Pack | Very Good | Excellent | Very Good | Excellent |
The main drawback is that the wide platform occasionally catches on rock edges during technical scrambling, making precise foot placement more challenging than with narrower designs.
Verdict: 9/10
Altra Olympus 6 Comfort
The 33mm stack height delivers serious underfoot protection that makes long trail days feel manageable.
From a comfort standpoint, you’ll appreciate how the thick midsole absorbs sharp rocks and roots, creating a buffer between your feet and whatever the trail throws at you. The premium Achilles pillow adds heel comfort, though it can cause fit issues for some runners.
| Comfort Feature | Altra Olympus 6 | HOKA Stinson 7 | New Balance More Trail v3 | Brooks Caldera 7 |
|---|---|---|---|---|
| Stack Height | 33mm/33mm | 37mm/32mm | 36mm/32mm | 30mm/26mm |
| Midsole Type | CMEVA | CMEVA | Fresh Foam X | DNA Loft v2 |
| Energy Return | Low | Moderate | High | High |
| Underfoot Feel | Firm/Protective | Soft/Plush | Bouncy/Responsive | Balanced |
However, the compression-molded EVA foam feels dated compared to modern alternatives. While comfortable for extended periods, it lacks the bouncy energy return that makes running feel effortless.
The foam has a firm, utilitarian character that prioritizes protection over performance.
Temperature sensitivity is another concern – the EVA becomes noticeably firmer in cold conditions, changing the ride quality between morning and midday runs.
Verdict: 7/10
Altra Olympus 6 Breathability
The engineered mesh upper represents a clear improvement over the Olympus 5, allowing more airflow through the tongue and toe areas. You’ll notice better ventilation during moderate conditions, but don’t expect stellar performance in hot summer weather.
| Breathability Aspect | Altra Olympus 6 | HOKA Stinson 7 | New Balance More Trail v3 | Brooks Caldera 7 |
|---|---|---|---|---|
| Upper Material | Engineered Mesh | Engineered Mesh | Synthetic/Mesh | Engineered Mesh |
| Overlay Coverage | Extensive | Moderate | Minimal | Moderate |
| Hot Weather Performance | Fair | Good | Very Good | Good |
| Moisture Management | Average | Good | Excellent | Very Good |
The extensive overlay coverage limits airflow compared to more minimalist trail shoe designs. During hot summer testing, heat buildup became noticeable after extended periods, making this less ideal for warm-climate runners or those who tend to overheat.
The thick construction that provides durability also traps heat and moisture more than lighter alternatives.
Verdict: 6/10
Altra Olympus 6 Weight
At 12.5 ounces for a men’s size 9, the Olympus 6 sits firmly in heavyweight territory. From a performance perspective, you’ll definitely feel this weight during climbs and longer runs where every ounce matters.
| Weight Comparison | Weight (Men’s 9) | Performance Impact |
|---|---|---|
| Altra Olympus 6 | 12.5 oz | Heavy – impacts climbing |
| HOKA Stinson 7 | 12.1 oz | Heavy – similar performance penalty |
| New Balance More Trail v3 | 12.8 oz | Heaviest – most noticeable on climbs |
| Brooks Caldera 7 | 10.9 oz | Moderate – better climbing performance |
The substantial mass becomes particularly noticeable when transitioning from lighter trail shoes.
| Shoe Category | Average Weight | Olympus 6 Weight | Difference |
|---|---|---|---|
| Racing Trail Shoes | 8-9 oz | 12.5 oz | +40-55% |
| Standard Trail Shoes | 9-11 oz | 12.5 oz | +15-35% |
| Maximalist Trail Shoes | 11-13 oz | 12.5 oz | -5% to +15% |
The weight comes from the substantial midsole, reinforced upper, and burly construction throughout. While this contributes to durability and protection, it significantly impacts agility and climbing efficiency compared to lighter alternatives.
Verdict: 5/10
Altra Olympus 6 Waterproofing
The standard Olympus 6 is non-waterproof, which works well for most trail conditions. The mesh upper drains reasonably quickly after water crossings, and the open design prevents the swampy feeling that waterproof shoes can create during extended efforts.
| Waterproof Options | Altra Olympus 6 | HOKA Stinson 7 | New Balance More Trail v3 | Brooks Caldera 7 |
|---|---|---|---|---|
| Standard Version | Non-waterproof | Non-waterproof | Non-waterproof | Non-waterproof |
| Waterproof Option | GTX variants available | No | No | No |
| Drainage | Good | Very Good | Excellent | Good |
| Wet Weather Performance | Fair (GTX: Good) | Fair | Good | Fair |
Altra offers GTX variants for wet conditions, but these add weight and reduce breathability. For most trail runners, the standard version provides the best balance of comfort and versatility.
Verdict: 7/10
Altra Olympus 6 Support
This is where the Olympus 6 truly shines. The zero-drop platform keeps your center of gravity low while promoting natural foot positioning. The ultra-wide base creates remarkable stability that inspires confidence on technical terrain, even with the high stack height.
| Support Feature | Altra Olympus 6 | HOKA Stinson 7 | New Balance More Trail v3 | Brooks Caldera 7 |
|---|---|---|---|---|
| Drop | 0mm | 5mm | 4mm | 4mm |
| Platform Width | Very Wide | Wide | Wide | Moderate |
| Lateral Support | Excellent | Very Good | Good | Good |
| Heel Counter | Firm | Moderate | Moderate | Firm |
The internal support cage through the midfoot adds structure without feeling overly rigid. Combined with the substantial midsole sidewalls, this creates a platform that makes you feel planted and secure on challenging trails.
The trade-off is reduced nimbleness during quick direction changes or technical scrambling where agility matters more than stability.
Verdict: 9/10
Altra Olympus 6 Fit and Sizing
The Olympus 6 runs small in length, so you’ll likely need to size up by half a size for proper fit.
The signature FootShape toe box provides incredible room for natural toe splay, but the midfoot can feel restrictive due to internal overlays.
The Achilles pillow, while intended to improve comfort, creates fit challenges for many runners.
Some find it makes the heel feel shallow and unstable, while others experience hot spots and blisters where it contacts the ankle.
| Fit Characteristic | Altra Olympus 6 | HOKA Stinson 7 | New Balance More Trail v3 | Brooks Caldera 7 |
|---|---|---|---|---|
| Length Sizing | Runs Small | True to Size | True to Size | True to Size |
| Toe Box Width | Very Wide | Moderate | Wide | Moderate |
| Midfoot Fit | Restrictive | Accommodating | Accommodating | Secure |
| Heel Lockdown | Variable | Good | Very Good | Excellent |
A heel-lock lacing technique helps address some concerns, though you need to work around the shortened tongue design that doesn’t extend as high as previous models.
Verdict: 6.5/10
Altra Olympus 6 Durability
Altra clearly addressed the Olympus 5’s durability issues with reinforced construction throughout. The 360-degree overlays where the upper meets the midsole should prevent premature failure, while the burly toe cap feels bombproof against rocks and roots.
| Durability Feature | Altra Olympus 6 | HOKA Stinson 7 | New Balance More Trail v3 | Brooks Caldera 7 |
|---|---|---|---|---|
| Upper Construction | Reinforced/Heavy Duty | Standard | Standard | Reinforced |
| Outsole Rubber | Vibram (Excellent) | Vibram (Excellent) | Blown Rubber (Good) | TrailTack (Very Good) |
| Expected Lifespan | 400-500 miles | 350-450 miles | 300-400 miles | 350-450 miles |
| High-Wear Protection | Excellent | Good | Fair | Good |
Early testing suggests the Olympus 6 will significantly outlast its predecessor. Multiple testers report minimal wear signs after 100+ miles of varied terrain, indicating this shoe is built for the long haul.
The substantial construction that adds weight also contributes to long-term durability, making this an excellent choice for high-mileage trail runners.
Verdict: 8.5/10

Altra Olympus 6 Review Summary
The Altra Olympus 6 succeeds as a purpose-built ultra-distance trail shoe but falls short of broader appeal.
Its strengths – exceptional stability, maximum cushioning, and bomber construction – make it ideal for long trail adventures where comfort trumps speed. The improved durability addresses major concerns from the previous model.
However, significant drawbacks limit its versatility. The heavyweight impacts performance, while the basic midsole foam feels dated at this price point. Fit issues with the Achilles pillow and restrictive midfoot may frustrate some runners, despite the generous toe box.
This shoe works best for ultra-runners, thru-hikers, and trail enthusiasts who prioritize protection and stability over speed and agility.
If you’re someone who values feeling completely secure and supported on long trail adventures, the Olympus 6 delivers. But if you want a lighter, more responsive trail shoe for faster efforts or varied terrain, you’ll find better options elsewhere.
The Olympus 6 represents solid evolution rather than revolution – it fixes the main issues with its predecessor while maintaining the core characteristics that made the Olympus series popular with distance trail runners.
Salomon Speedcross 6: The Better Altra Olympus 6 Alternative
While the Altra Olympus 6 excels in specific areas, many runners would benefit from considering the Salomon Speedcross 6 as a more versatile alternative.
At $130, it offers better value while addressing several of the Olympus 6’s key weaknesses.
The Speedcross 6 weighs just 9.8 ounces (men’s size 9), making it nearly 3 ounces lighter than the Olympus 6. This weight savings translates to noticeably better climbing performance and reduced fatigue during longer runs.
The aggressive lug pattern provides exceptional traction that rivals the Vibram Megagrip, particularly in muddy conditions where the deeper lugs excel.
Where the Speedcross 6 really shines is energy return. The EnergyCell midsole foam feels far more lively than the Olympus 6’s basic EVA compound, providing bounce and responsiveness that makes running feel more effortless.
The 10mm drop may require an adjustment period for zero-drop devotees, but most runners find it more comfortable for varied terrain.
The main trade-offs are reduced stack height (22mm heel) and a more traditional toe box shape. Runners who specifically need Altra’s foot-shaped design or maximum cushioning won’t find adequate replacements in the Speedcross 6.
But for most trail runners seeking better all-around performance at a lower price, the Salomon option delivers superior value.
