Thanks to its particularly grippy sole and the climbing zone in the toe area, which is suitable for use on the wall, the La Sportiva Boulder X is especially well-suited for technical approaches and via ferratas. The upper is made of suede leather with a rubber rand all around for maximum protection against wear during climbing. The patented lacing system, derived from the design of the Mythos climbing shoe, as well as the fit, are asymmetrical. The sole features a new Vibram concept with a design that enhances grip during climbing and an Impact Brake System for better traction when descending. The use of soft 2 mm EVA provides anti-shock properties.

The Impact Brake System is an innovative system attached to the sole that absorbs impact, aids in ascent, and prevents slipping during descent.
