The latest version Boreal Ninja revisits the groundbreaking performance of the original, updated with modern materials and design. It is very asymmetric and downturned to focus weight and power to the toe, for precision and micro-edge performance. The half-length midsole permits enough flex for smearing, and the moulded heel cup and torsion band over the toes maximise control during heel and toe-hooks. It’s slip-on, elasticated fit makes it particularly suited to technical bouldering. The synthetic materials also mean the Ninjas are free from animal products.
