Arcus is made for long runs or for those that wants more support also at shorter distances. Superior comfort and traction on all winter roads. Arcus BUGrip is the perfect shoe for those looking for extra cushioning, whether it might be for longer runs, recovery runs or when running with a backpack. To enhance the comfort and great running feeling it has a rocker midsole to reduce pressure on the forefoot and heel and aid the momentum forward - giving a smooth stride. The midsole has higher density in the front giving a more responsive toe-off. This gives great comfort on longer runs and yet provides responsiveness and a great running feeling. Combined with a light upper with midfoot lock, the BUGrip outsole has thirteen dynamic studs that provide reliable traction on all winter surfaces.
