[This review was collected as part of a promotion.] I found them very comfortable and felt confident on trail terrain. They grip the surface well, both at the toe and the end of the foot, providing security. I've gotten them wet and they've soaked through mud, and they dried quickly.
[This review was collected as part of a promotion.] I recently picked up the New Balance Fresh Foam X Hierro v9 for trail running, and they’ve been a solid choice, especially in snowy and leafy conditions. The traction holds up well, offering great stability without feeling overly rigid, which is perfect for mixed terrain. One thing to note — they run a little tight in the toe box. I had to go up a full size for a comfortable fit, so I’d recommend sizing up if you prefer a bit more room up front. What really impressed me was how resistant to staining these are. After muddy, wet runs, they clean up incredibly easily, which is a huge plus for anyone hitting the trails regularly. Overall, they’ve proven reliable, durable, and comfortable once you get the sizing right. A great option for trail runners looking for performance and practicality.
These shoes are fashionable and functional. I wear them to work, the gym, for walking/jogging, and I wear them with my daily outfits because they’re stylish too. I’m a huge fan!! I feel like I’m walking on clouds, my feet love the extra cushion, and I’m grateful for the toe protection, especially for the type of work I do.
[This review was collected as part of a promotion.] They are excellent for long trail runs in hard surfaces they offer great support and protection
Have been excited to retire my much-loved NB Hierro v7 trail running shoes that served me sooooo many great miles of trail jaunts. Was even more excited that the Hierro v9 was being offered in all-black color-way. 😎 I ordered the same size as my v7 pair. I was stoked to receive them this week and maybe should have trusted my gut response when I tried them on and felt they were definitely not the same as the v7’s… The v9’s immediately felt a little tighter than my previous pair in the same size and much more foam-y in the stack. I decided to go ahead and keep them and hope they could be better in real action. I took them on a familiar trail run (3 miles, 900’ elev change, very rocky) and was not as pleased as I’d hoped for this new pair of Hierros. The cushion/sole is soft and thick and makes my feet float around in the shoe. At one point I rolled my ankle and barely avoided a bad situation. The width seems less than the v7‘s too and I felt my outer toes becoming numb from this first wear. Annnd the shoelaces are weak compared to previous v7. On the plus side: the lug pattern and the vibram sole are amazing, and the upper mesh is breathable.
[This review was collected as part of a promotion.] These NB Hierro V9 are great for trail running. I jogged 5 miles on the trail during winter/a little snow. They have a good grip. I love them already. Can’t wait for the spring trail run. Good cushioning and traction. It is very comfortable and roomy toe box. Since They have a Vibram Megagrip. I wear them for snow days as well.
[This review was collected as part of a promotion.] The outsole is grippy and i really like the cushioning! Suitable for long trails and hybrid.
These shoes are amazing! The fit and the support are unmatched. The grip/traction when hiking is what you’d expect and want from a hiking shoe. I highly recommend these shoes for anyone that’s looking for a pair of trail runners/ hiking shoes!
[This review was collected as part of a promotion.] Great responsiveness. I felt safe being on the trails and on fresh snow. My feet felt stable in my Hierros despite of change in drastic elevations. No pain or discomfort after being in them for nearly a day of activities!
I really like it, it's easy to walk because the shoe wide.. I'm looking for one more in the future.
