's Hierro trail weapon is back and ready for more in it's 9th generation. Packing more cushioning thanks to the Fresh Foam X midsole and more traction thanks to a lugged Vibram® outsole—the Hierro is equipped for whatever nature can throw at it.

The engineered mesh upper has been refined with a more comfortable and secure fit along with abrasion-resistant 'Toe Protect' TPU bumper whilst the burly heel pull-tab allows for easy on/off.

Under-foot a thick midsole sporting 42mm of NB's Fresh Foam X cushioning soaks-up undulating terrain while the Vibram® Megagrip outsole has 6mm lugs for excellent traction in all conditions.
