Tatanka, the most asymmetrical of Tenaya's laced models, is a high-performance climbing shoe designed to take maximum advantage of the biomechanical properties of your feet in order to make climbing easier. When attempting the hardest moves on rock, time is often a critical factor, and this shoe responds quickly to all kinds of difficult situations. The shoe fits like a glove and includes SXRDynamics - a moving tightening system. Modifications in the sole and structure have allowed us not only to increase the precision and comfort, but also allow the foot to employ its maximum strength. Tatanka also has a quick and effective lacing system, a perfect combination of materials, and a powerful heel, giving great results on difficult rock climbs.
