Ninja 2018



My vote: None ( 4.8 avg )


Boreal Ninja is a true classic; the original, definitive climbing slipper. Soft, sensitive and sticky.

A premium quality unlined split leather upper with elasticated foot wrap system hugs the foot while retaining maximum sensitivity. A tension band across the forefoot prevents unwanted “bagging” at the toe and adds friction during tricky toe-hook moves.

Sticky FS Quattro™ rubber and soft half midsole mean that the Ninja is incredibly adept at padding up friction slabs. This ultra lightweight shoe changed what was possible when it was introduced over 25 years ago. This legendary shoe is still an ideal choice for any route or problem where sensitivity is paramount.
