Overview The Men's 001A is Norda's optimally-cushioned ultra distance trail shoe, built around an all-new Arnitel midsole that delivers responsive, long-haul cushioning without the weight penalty of traditional foam. The upper is constructed from bio-based Dyneema - one of the most durable fibres available - wrapped around a last shaped for sustained effort over technical terrain. Where the original 001 set the template, the 001A refines it for runners who log serious miles on the trail. Details Features Arnitel bio-based midsole tuned for ultra-distance cushioning and energy return over extended efforts. Bio-based Dyneema upper provides cut and abrasion resistance at a fraction of the weight of conventional materials. Vibram outsole compound delivers multi-surface grip on wet rock, rooted singletrack, and packed dirt. Low-profile construction keeps the foot close to the ground for proprioceptive feedback on technical terrain. Seamless upper geometry reduces hot spots and pressure points during high-mileage days. Reinforced toe box and heel counter protect against trail debris without adding bulk.
