New Balance Fresh Foam X Hierro v9 ($155)
Introduction
The New Balance Fresh Foam X Hierro v9 is the latest version of a popular trail running shoe that has been delivering both comfort and performance for years. With some noticeable updates including a Vibram MegaGrip Traction Lugoutsole and more stack height, it has a clear focus on comfort and cushioning, the Hierro v9 promises to be an ideal companion for longer and less technical trail runs. I have tested the shoe extensively and would like to share my experiences and impressions with you.
Pro & Cons
Pros:
- Comfortable cushioning: The FreshFoam X midsole provides a very comfortable and soft ride, ideal for longer runs.
- Improved grip: The Vibram MegaGrip Traction Lugs offer significantly better grip on various surfaces compared to its predecessor.
- More cushioning: Increase in stack height of 4mm at the heel and 6mm at the forefoot
- Space in the forefoot: Plenty of room for runners with wider feet, which increases comfort.
- Stability: The bathtub design ensures that the foot sits securely in the midsole.
- Design updates: The removal of the "rear spoiler" reduces dirt splashes
Cons:
- Weight: At 329 g in size 44.5, the shoe is comparatively heavier, which can be noticeable at longer distances.
- Loose fit: The shoe offers too little support in the midfoot area for narrower feet.

First impressions, fit and upper
With a weight of 329 g in size EU 44.5/US 10.5, the Hierro v9 weighs 23 g more than its predecessor with to consider more stack height of cushion. Despite the increase in weight, the shoe impresses with sensible design changes.
The upper material has been subtly changed.
Lacing loops have been revised and are now reminiscent of the Venym. The laces themselves are now also very stretchy and slightly shorter, which means there are no longer as much length left over after tying.
The heel pull on loop is practical.
There are fewer overlays giving the design a cleaner and more modern look.
One of the most striking changes is the absence of the so-called "rear spoiler" - the protruding outsole on the heel, which previously tended to kick up dirt rather than offer any functional benefit.
In addition, the forefoot area offers plenty of space, which is a plus point especially for runners with wider feet. However, the support in the midfoot area could be better. The shoe was a little too loose for my narrower foot, which affected the fit. On a positive note, the tongue is stitched to the side, which prevents it from slipping and ensures a stable fit.
Midsole and Platform
The midsole of the Hierro v9 has been upgraded: This latest Fresh Foam X foam now provides even softer and more comfortable cushioning. With an increase in stack height of 2 mm in the heel and 4mm at the forefoot midsole stack height to 42mm heel / 38mm forefoot, the shoe is now for sure a maximum cushioning model. With the predecessors, especially the Hierro 6 and 7, I found the cushioning in the forefoot to be a little too thin. The Hierro 8 brought improvements, but the v9 goes one better and offers more than enough cushioning. The foot sits securely in the midsole instead of just on it - a so-called bathtub design that also provides better stability.
Outsole
A highlight of the Hierro v9 is the new outsole with Vibram Traction Lugs. These provide a significantly improved grip compared to its predecessor, the Hierro v8.
Whether on wet or dry trails - the traction leaves nothing to be desired and provides a high level of safety, even in difficult conditions. This improvement is a real step forward and makes the shoe particularly attractive for trail runners who value a secure grip.
Ride
The Hierro v9 is designed for comfort. Due to the increased cushioning and slightly higher weight, the shoe is mainly suitable for easy trails and less technical terrain. It rolls smoothly on moderate and firm surfaces and provides an extremely comfortable ride. For technical trails, however, the shoe lacks reactivity. If you are looking for a shoe for demanding terrain, you won't find it here - but the Hierro v9 is perfect for relaxed, long runs on easy trails.
Conclusions and recommendations
The New Balance Fresh Foam X Hierro v9 is an all-round trail running shoe for anyone who values comfort and cushioning. With its improved midsole, the new Vibram outsole and the sensible adjustments to the upper material, the shoe offers a very pleasant running experience on less technical trails. The shoe's greatest strengths lie in its soft cushioning and secure grip, while the shoe is not as strong in terms of being stable, reactive and agile at faster paces. If you are looking for a comfortable shoe for long, relaxed trail runs, the Hierro v9 is the perfect choice.

3 Comparisons
NB Fresh Foam Hierro v8 (RTR Review)
The v9 is now a real maximum cushioning shoe for the trails. Compared to the v8, it loses a little in stability for more technical terrain. But now I know where to place it. With the v8, I still had the impression that it wanted to be a maximum cushioning shoe, but wasn't quite there yet.
Saucony Xodus Ultra 3 (RTR Review)
Both shoes are quite similar. I think the Hierro is slightly ahead in terms of the outsole and grip. The midsole of the Xodus Ultra is also a little less soft, which makes it a little more stable. All in all, however, there is not much difference between the two.
Hoka Speedgoat 6 (RTR Review)
The SG 6 rolls a little better thanks to its stronger rocker, but both are very similar in terms of feel. Where they differ the most is in the fit. The SG 6 offers better support around the midfoot and is significantly narrower in the toe area. The Hierro is much more generous there. The Speedgoat 6 also has a significant weight advantage at about the same stack height.

Since he stopped playing soccer, running has become his main sport to stay fit. He now runs between 60 and 80 kilometers per week, 5-6 times a week. Apart from a local relay race, he rarely runs races. Markus runs both on the trail and on the road and is an absolute gear geek. Besides running, he spends most of his free time hiking, especially in the mountains, where his interest in equipment also comes into play.

I have never worn the Hierro line as they just weren't wide enough, even in the wide width. Had all versions of Fresh Foam X Trail More and really enjoyed they, and this seem a lot like that shoe from the look of it. I would even say maybe taking its place. Great review and just wondering if you have worn any Topo trail shoes and how it would compare?
I fear I'm going to be in a minority in being disappointed this shoe has gained stack height. I didn't buy earlier versions because the lugs looked too minimal, but decided to give v8 a go, because it's so difficult to find shoes with sub-max cushion that can handle winter trails [i]and[/i] tarmac. This new version would be too much shoe for me. Disappointed that I'll have to start the search for a versatile door-to-technical trail shoe again so soon. Maybe the Scarpa Golden Gate?? It feels as if shoes are becoming increasingly specialised and the versatile, middle of the road (or trail!) shoes that are appreciated by recreational runners without deep pockets are being squeezed out of the market.
I miss a comparison with the other NB maximalist shoe:
