Sticky Slipper: Boreal Ninja Climbing Shoe Review

The Boreal Ninja’s impeccable fit and performance characteristics make it an excellent choice for sport climbing. Plus, the convenience of a slipper makes it an especially good choice for gym climbing and bouldering. For the climber with “duck feet,” the Ninja will be hard to beat on fit, as long as the heel fits in the heel cup. I have access to a massive array of sport climbing shoes, and the Ninja is my current leader for fit and comfort in a high-performance slipper.
