New Balance’s Hierro is designed for life on the trails, and it’s in its sixth generation now, which means more tech developments than ever. This pair retains the Fresh Foam cushioning and Vibram® outsole from previous versions — because you shouldn’t fix what isn’t broken — but the mesh upper is reworked with TPU threads to provide targeted support where it’s needed. - Textile Uppers - Heel Pull - Fresh Foam Midsole - Vibram® Outsole
