The Shakra utilizes the same technology, "Love Bump and "Knuckle Box" as the highly successful Shaman in a lower volume and narrower fitting design. An amazing fit, a dual hook and loop closure system, and side-pressure relief rand design make it an extremely comfortable high performance climbing shoe. We've added even more rubber for optimal toe hooking, and with a more sensitive midsole than the Shaman, the Shakra connects you to the rock and gives you the edging power you need.
