Sequential cruxes demand perfection. Your fingertips have to be perfectly aligned if they're going to grip the hold, in the same way that the Black Diamond Women's Focus Climbing Shoe's rubber needs to be perfectly aligned along the microscopic edge if you want to stay standing. Black Diamond designed this aggressive shoe for this kind of perfect precision, with a slight downturn that edges and grips on vertical to gently-overhung problems and routes. Medial and lateral stabilizer rands keep your foot solid when you're edging, and the single-molded NeoFriction rubber sole won't peel away in the same way that standard climbing shoes do. Black Diamond coupled the leather upper with a odor-reducing hemp liner and a knit tongue for amplified ventilation.
