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. As with all Tenaya climbing shoes, the comfort and quality are unrivaled.
