These outsoles have been tested with bindings representing the full range of release kinematics on currently available alpine bindings and provide release values consistent with ISO 5355-certified boots.
GripWalk Outsoles
Removable and interchangeable ISO 23223 alpine rockered soles collaboratively designed to work with Marker’s Grip Walk binding system for better grip and added comfort when walking and standing in boots, but doesn’t compromise the power transmission and release function between the boot and binding when skiing. Preinstalled.
