The Tarifa is a powerhouse of performance thanks to the new RB Range X technology (Maximum Range of Response and Balance). The RB Range X system creates a dynamic response and provides unparalleled balance in the shoe, making climbing feel both easier and more intuitive. Its conforming last and mid-stiff midsole are sensitive enough for steep terrain, but hold up to the demands of vertical edging on tiny holds. The speed-lace system offers quick entry with the precision fit of a lace-up, and the 3.5mm Vibram XS Grip rubber provides unmatched friction and durability. In order to achieve maximum performance in every situation, from micro edges to sloping heel hooks, the TARIFA uses different rubber formulations for different parts of the shoe. As with all Tenaya climbing shoes, the comfort and quality are unrivaled.
