I recently bought a pair of the latest version of the New Balance Fresh Foam Hierro. This v4 was released early this 2019 and I couldn’t find a lot of reviews on it yet. But since it was stocked at the local shoe store, I had the time to fit it and was happy with how it caressed my foot. So I got the pair with the help of my friend Nik, and I broke it in on a fast hike through Mt. Ulap and an ultramarathon up Mt. Apo. Here are my impressions.
