The Boreal Ninja, the first-ever slip-lasted shoe, has been updated for 2019 with a number of modern features. It has an aggressive downturned profile with sticky Zenith Ultra rubber and a simple elasticated closure. The last shape cradles the foot and maximizes toe power. The rand supports the foot, while the integrated tongue makes for easy fitting. The unlined synthetic upper makes it super comfortable. The Ninja gives you power in a precise high-performance slipper. A great choice for serious sport climbers.
