Positive

After three months, an older ultra runner loves the Hierro v9 for the protection it gives on long days.

Positive

A runner was very pleased with the Hierro v9's comfort over a 50K trail race with 2500 m of climbing.

Positive

About 50 km through a muddy UK winter, from easy runs to a 20 km long run, on hard-packed trails, mud and icy pavement. They found it a comfortable, protective shoe with plenty of cushioning and grip that coped with most conditions, but it is a big shoe, not nimble, and not for fell running or fast efforts. Toes hit the front on downhills, so they would go half a size up. Suits easy, relaxed trail and road-to-trail running.

Positive

A plush, protective shoe that shines over long distances and ran her through a 100 km ultra: ample cushion, a breathable upper and a grippy Vibram outsole. The roomy fit suits swollen feet. The midfoot was loose for her and she had to re-cinch it at ~60 km. Not the most agile on technical trails.
