The Arcus is equipped with an integrated Gore-Tex membrane in the upper, and the shoe is both waterproof and comfortable. The Arcus is a good choice for longer runs, recovery runs or when running with a backpack. The moulded midsole provides a responsive feel and increased precision, so that the shoe retains both its shape and feel workout after workout. The BUGrip® outsole has 13 dynamic carbide steel studs for the best possible grip on uneven surfaces.
