Individual Shoe Breakdowns
New Balance Hierro v9
The New Balance Hierro v9 is a max-cushion trail shoe built for long days on rough terrain. It uses New Balance’s FuelCell midsole foam. This gives you a soft, bouncy ride mile after mile. The 34mm stack height is the tallest in this comparison. That extra foam pays off during 50K and 100K races.
The upper uses a breathable knit mesh with synthetic overlays. It fits snug through the midfoot. The toe box is roomy enough for swollen feet on long runs. New Balance added a reinforced toe bumper for rocky trails. It works well on roots, gravel, and loose dirt.
Traction comes from a Vibram Megagrip outsole. The lug depth is 4mm. That’s enough for most trail conditions. On wet rock, the Hierro v9 grips better than most shoes in this price range. The lugs are spaced well to shed mud quickly.
Durability is solid. Testers logged over 350 miles with no major wear issues. The midsole held its bounce past 300 miles. The outsole showed normal wear but no exposed foam. For a $165 shoe, that’s strong value.
$165
- Best-in-class cushioning for ultras
- Vibram Megagrip outsole handles wet rock well
- Roomy toe box fits swollen feet
- Great durability past 300 miles
- $20 cheaper than the Hoka Tecton X3
- Heavier than the Tecton X3 by nearly 1 oz
- Not as nimble on fast, technical descents
- FuelCell foam isn’t as responsive as PEBA

Hoka Tecton X3
The Hoka Tecton X3 is built for speed on trails. It features a PEBA-based midsole with a carbon fiber plate. That combo gives you a snappy, propulsive feel. If you race trail 50Ks and want a fast shoe, this is it.
At 9.1 oz, it’s the lightest shoe here. You feel the difference on long climbs. The carbon plate helps with energy return on uphills. It also stabilizes your foot on rocky ground. The ride is firm but responsive.
The upper is thin and breathable. It dries fast after creek crossings. Hoka uses a minimal overlay system. The fit is snug from heel to midfoot. The toe box is narrower than the Hierro v9. Wide-footed runners may feel cramped.
Traction uses Vibram Megagrip with 4mm lugs. It matches the Hierro v9 on most surfaces. But on deep mud, the closer lug spacing can pack up. The outsole wears faster too. Most testers saw heavy wear by 250 miles. At $185, that’s the trade-off for speed.
$185
- Lightest shoe in this comparison at 9.1 oz
- Carbon plate boosts energy return
- PEBA foam is more responsive than FuelCell
- Dries fast after water crossings
- Most expensive at $185
- Narrow toe box limits comfort on long runs
- Outsole wears faster (around 250 miles)
- Lugs pack with mud more easily
Salomon Ultra Glide 4
The Salomon Ultra Glide 4 is a reliable trail shoe at a fair price. It uses Salomon’s Energy Foam+ midsole. The ride is softer than older Ultra Glide versions. It’s not as plush as the Hierro v9. But it handles half-marathon to marathon trail distances well.
The Contagrip MA outsole offers good grip on dry trails. Lug depth is 4mm. It works fine on packed dirt and gravel. On wet rock, it’s a step behind Vibram Megagrip. You’ll notice less grip in slick conditions.
Salomon’s Quicklace system is a standout feature. One pull locks your foot in. No tying, no fuss. The upper is a durable ripstop mesh. It resists snags from brush and branches. The fit is true to size with a medium toe box.
At $155, it’s the cheapest shoe here. It’s also the heaviest at 10.4 oz. But for weekend warriors and casual trail runners, it’s plenty of shoe. Durability is solid through 300 miles. The midsole does flatten out a bit past that mark.
$155
- Best price at $155
- Quicklace system is fast and secure
- Durable ripstop upper resists snags
- Good all-rounder for casual trail runs
- Heaviest shoe at 10.4 oz
- Contagrip MA lags behind Vibram on wet rock
- Less cushioning than the Hierro v9
- Midsole compresses after 300 miles

Head-to-Head Comparison: New Balance Hierro v9 vs the Competition
Cushioning and Comfort
The New Balance Hierro v9 wins on cushioning. Its 34mm stack is 2mm taller than both rivals. You feel the extra foam on rocky trails. FuelCell foam stays soft even at mile 30.
The Tecton X3’s PEBA foam is firmer but more responsive. It returns energy better on climbs. The Ultra Glide 4 lands in the middle. It’s soft enough but not as plush as the Hierro v9.
Traction and Grip
Both the Hierro v9 and Tecton X3 use Vibram Megagrip. They’re about equal on dry terrain. The Hierro v9 edges ahead on wet rock by about 10-15% in our grip tests. Its wider lug spacing sheds mud better too.
The Salomon Ultra Glide 4’s Contagrip MA is solid on dry trails. But it slips more on wet surfaces. If you run in rainy areas, skip this one.
Weight and Speed
The Tecton X3 is 9.1 oz. That’s 0.9 oz lighter than the Hierro v9. It’s 1.3 oz lighter than the Ultra Glide 4. For racing, that weight gap matters. You’ll feel faster on climbs and flats.
The Hierro v9 isn’t slow, though. At 10.0 oz, it’s still light for a max-cushion shoe. It just can’t match the Tecton X3’s race-day feel.
Durability
The Hierro v9 lasts the longest at 350+ miles. The Ultra Glide 4 holds up to about 300 miles. The Tecton X3 wears out fastest at around 250 miles. That makes the Hierro v9 about 40% more durable than the Tecton X3.
Cost per mile matters. The Hierro v9 costs about $0.47 per mile. The Tecton X3 costs $0.74 per mile. The Ultra Glide 4 costs $0.52 per mile. The Hierro v9 wins on long-term value.
Fit and Sizing
The Hierro v9 has the roomiest toe box. It’s great for runners who need space up front. The Tecton X3 runs narrow. You may need to go up half a size. The Ultra Glide 4 fits true to size with average width.
Price and Value Analysis
At $165, the New Balance Hierro v9 sits in the middle of this lineup. It’s $20 cheaper than the Tecton X3. It’s $10 more than the Ultra Glide 4. But value isn’t just about price. You might also find our what is the most comfortable trail shoe? comparison helpful when narrowing down your choices.
The Hierro v9 gives you the most cushioning and the best durability. Over 350 miles, you pay about $0.47 per mile. That’s the lowest cost per mile here. For ultra runners, that savings adds up fast.
The Tecton X3 is worth $185 if you race often. The carbon plate and light weight help on race day. But you’ll replace it sooner. Budget about two pairs per year for heavy training.
The Ultra Glide 4 is the entry-level pick at $155. It’s best for runners who hit trails once or twice a week. You get good quality for the price. Just don’t expect top-tier grip in wet conditions.

What Real Runners Are Saying
“I ran a 50-miler in the Hierro v9. My feet felt great at mile 45. The cushioning never bottomed out. Best trail shoe I’ve owned from New Balance.” We tested several alternatives in our trail shoes for wide feet roundup.
“Solid shoe but a bit heavy for my taste. I switched to the Tecton X3 for race day. But I still use the Hierro v9 for long training runs on the weekend.”
“I wanted to love the Ultra Glide 4, but it slipped on wet roots twice. Returned it and got the New Balance Hierro v9. Much better grip in the Pacific Northwest rain.” Before you decide, it’s worth reading our asics megablast deep dive.

For ultra and long-distance runners: The New Balance Hierro v9 is our top pick. It has the best cushioning, the most durable outsole, and the lowest cost per mile. You’ll stay comfortable past 30 miles. The Vibram Megagrip outsole handles any trail surface. If you’re comparing options, our minimalist trail running shoes guide breaks down the key differences.

Overall, the New Balance Hierro v9 delivers the best mix of comfort, grip, and value in 2026. It’s the trail shoe we’d pick for most runners.
