Positive

With narrow feet, the Hierro v9 feels great with no toebox tightness.

Positive

Tested from an 8-mile run in 95-degree Maui heat to snowy Eastern Washington, mostly on hard-packed trails. They like the roomy but secure fit, breathable mesh upper, smooth rocker, protective feel on jagged rocks and grippy outsole, with only minor slipping in deep mud. The ground feel is muted, which will not suit those wanting feedback, and the breathable upper is not sealed off for winter, so waterproof socks are suggested in mud. A solid pick for newer trail runners and mixed road-and-trail routes.

A 180 lb runner has enjoyed the Hierro v9 for all their trail runs; the wide version fits the toebox perfectly.

Positive

A 115 kg runner with narrow feet found the Hierro v9 fits perfectly with strong cushioning for forest and light trails.

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.

Blog · Tom’s Guide – Nick Harris-Fry · summarized

Positive

A comfortable, grippy road-to-trail shoe that he could also use as a daily trainer, bringing a cushioned road-shoe feel off-road with added stability. No lug wear after 40 miles. Not for nimble running on technical mountain trails.
