The name is a bit of a giveaway; the Ultra Fastpack III Shoes are engineered for pacey through-hikes, when you're blurring the boundaries between trail running and hiking. For this reason they're made from a lightweight, abrasion-resistant woven upper that's optimised for hot-footing it along rough and rugged trails. And for 2020 we've harnessed breathable-waterproof FUTURELIGHT™ technology. The membrane will breathe as hard as you do when pacing it up a steep ascent. Unlike paved roads, trails can be dusty, rocky, gravelly or wet, slippery, boggy and muddy; the Ultra Fastpack III Shoes take all this in their stride. They feature a gusseted tongue for keeping debris at bay; TPU toe caps minimise the chance of stubbing toes and losing toenails; and the Vibram® Megagrip soles provide traction in all conditions. For cruising-speed comfort you've got OrthoLite™ insoles that retain their cushioning power despite a real pounding. Dual-density FastFoam™ in the midsole provides responsiveness, inherent stability and arch support. EVA foam rubber creates a soft yet energy-returning landing and ESS shanks create torsional rigidity and support over uneven ground.
