Upgrading the Ultra Fastpack with Futurelight technology, this hiking shoe helps you log more miles, faster, and with more comfort. An abrasion-resistant mesh upper with TPU overlays offers the support of a burlier boot without the extra weight, and a FutureLight membrane keeps wet weather at bay while allowing your foot to breathe. The FastFoam midsole provides the right combination of cushioning and support, with high-energy return at a low weight, and the Ortholite X35 Hybrid footbed further absorbs impact for fresh feet through the miles. To ensure reliable traction on any surface, TNF rounded this boot out with a grippy and durable Vibram MegaGrip outsole.
