La Sportiva's Boulder X Approach Shoe have been designed for  more technical crag approach, Via Ferrata and scrambling. The new improved sole is made from ultra sticky Vibram rubber, and has what Sportiva call an Impact Braking System, which they say offers enhanced braking capacity on steep descents. The boulder X also comes with their patented asymmetric lacing system first pioneered in the Mythos climbing shoe - this gives you the ability to get the shoe extra tight when and where you need it.
