The NEW BALANCE M Hierro V9 (2E) BLACK is a men’s trail running shoe built for rugged off-road terrain with a wide (2E) fit that offers extra room and comfort. It features a dual-density Fresh Foam X midsole for plush cushioning and smooth landings, paired with a Vibram® MegaGrip outsole that delivers aggressive traction and secure grip on wet, muddy, or rocky surfaces. The breathable engineered mesh upper includes protective overlays and a gusseted tongue to keep out debris, while the low 4 mm heel-to-toe drop encourages a natural stride. This combination makes the shoe supportive and comfortable for long trail runs and varied terrain.
