Lighter and more durable than the original, but still delivering award-winning performance and comfort, the Norvan LD is the shoe for long-distance trail runs. Created for daylong runs on shifting terrain, the LD leverages progressive materials and construction to shave grams and elevate durability. The all-season Vibram® Megagrip outsole utilizes their LITEBASE technology, and combines with a new midsole material and lighter, stronger, exceptionally breathable upper to shed weight.
