The Arcteryx Norvan LD 3 GTX is a lightweight, long distance GORE-TEX waterproof running shoe for high milage comfort in cold and wet conditions. It features a breathable yet exceptionally hydrophobic and hard wearing Cordura upper mesh which also easily folds down for space saving when packing. It has a Vibram MegaGrip outsole with aggressive 4mm lugs designed to perform in all terrain in both the wet and dry, combined with a Vibram LiteBase midsole to reduce the overall weight. The integrated sockliner is designed to keep dirt and debris out of the shoe whilst providing comfortable support for your foot. The midsole includes an anti fatigue insert and has a 9mm drop with a total 18mm stack height to maximise comfort on runs that last all day.
