I do a good amount of contract work for a shop that does not have the proper tools.
Cantology shims:
Station where I do the measuring along with plumb bob and shims for measuring.
For solid sole boots, I will plane the soles with a jointer:
A routing table with SVST blocks to rout the proper toe and heel height to make them DIN standard
Custom bracket used to resole
K2 Recon Pro that is is Cantology compitable:
Before trimming:
I would have preferred to have a lighter colored boot so show the final work.
@Tricia's old boot that was canted (left boot) and leg length (right boot) with GripWalk soles
Note with canting with GripWalk. Gripwalk soles must be removed BEFORE Routing of lugs. Routing MUST be done with the DIN sole on boot, then the GripWalk reinstalled.
