La Sportiva Katana Climbing Shoe. The Katana from La Sportiva is a high performance, velcro closure climbing shoe for a variety of climbing surfaces. This shoe is constructed with leather lined with both Pacific in the forefoot, which provides toe knuckle comfort, and Dentex in the back to absorb sweat. Additionally, the Katana has a Lorica toe box and an innovative powerhinge sole cutout to control and minimize forward stretch, as well as a slingshot rand to transfer power efficiently. The last on this shoe is relatively flat, which makes the Katana an excellent all around shoe for sport climbing, face climbing, gym climbing and bouldering.
