Their construction makes these climbing shoes particularly good for challenging sport climbing and bouldering. The upper material feels comfortable against the feet and, in combination with the Bi-Tension technology, ensures that tension in the forefoot area is transferred to the arch. This creates a balanced relationship between flexibility and tension.The lacing in this version of the shoes also enables precise adjustment. Two practical pull-on loops make them easier to put on. This model is designed to fit medium-width feet with a “Greek” foot type (where the second toe is longer than the big toe). The sole is made of Vibram XS Grip 2 rubber so it is mainly designed for performance and grip. Its positive effects can mainly be felt on demanding routes with a lot of overhangs. The rubber coating has also been extended in the heel and toe areas. This makes it easy to position and hold toe and heel hooks and also protects the upper material from damage.
