Customer Images

Here's what customers have to say

The shoes are described as lightweight, responsive, and providing excellent support and stability, suitable for both trail running and hiking. However, some customers have noted issues with the fit, particularly those with wider feet, as the shoes run narrow even in the wide version. A few comments also mention the shoes feeling too high-stacked or unstable on uneven ground. Most customers seem satisfied with the durability, though a small number have reported the midsole breaking down or the shoes becoming deformed after moderate use. The laces have also been criticized by some as being too short.

The Most Comfort Trail Shoes

After run this shoes on trail in Malaysia for 55 km, I like how the comfortable it is in the Fresh Foam. It just gives me some bouncy & comfort when went for long trail run. It is hybrid shoes that suitable for terrain in Malaysia. Just concern on the sizing. Before purchased, I did a lot of study & reviewed from others who already tried the Hierro V9. They said it little bit narrow or snug in toebox part. I went for 0.5 half size up & it was wise choose because it give my toe some room to move

not even close !!!

This shoe collapses inward in the forefoot. The heel is so sloppy and unstable. This shoe is absolute garbage compared to the More Trail v3. I have gone back to La Sportiva Prodigio Pro and Max.

A delight for wide feet

We purchased these shoes in as wide as they come for my husband’s 4E feet. He can’t stop raving about them. He says they are the first shoe in his 48 years that was comfortable out of the box. They even accommodate his orthotics. We will buy more to have on hand.

Beautiful and comfortable!

I bought these to replace a pair of MoreTrailV3's. I'm an older runner and was worried these might not be cushioned enough, but I have been very impressed. They feel very comfortable underfoot, and also more stable and supportive. Extremely comfortable from the first run. I also love the colour!

Who is picking these colors?

Please come out with a decent color for the Fresh Foam X Hierro v9. The current 90's minivan, nothing but beige, and Pepto puke colors are ridiculous. We can't even get black anymore. This will be the first year I'm not buying a new pair of Hierro's in 5 years.

Very soft soles

Soles are very soft with a little too much give, build quality very good but toe box a bit tight

Comfort and style

Fresh Foam is the best and most comfortable shoe I have found. Walking or running is easier and more comfortable. These are also such an unusual color, so bonus points for style
