The Men's Boulder X is a classic approach shoe from La Sportiva. Protective leather uppers and a reinforced rand deliver the durability and abrasion resistance required on rocky terrain. Derived from the Mythos climbing shoe project, the patented asymmetric lacing system creates a superior fit. Finished with a proven Vibram IdroGrip sole: Impact Brake System lugs and a climbing zone at the toe make light work of mountain paths and via ferrata routes.
