These climbing wires fit with our custom no drill heel pieces that are used with the 3pin or 3pin cable bindings. Like the heel pieces, the wires are adjustable to fit all boot sizes. There are 3 slots in the base of the heel piece as well as the two positions (via the inserts) for the heel pieces on the Hok. The heel wire adds about 15mm in height.
No springs or tension devices makes our climbing wires flip up and down easily, and they rest securely on the heel piece. The wires come in a set of two and are attached using the existing screws in the heel pieces.
