I dropped off my boots today at a local shop to have the Hotrionic boot warmer installed. I asked how they install it since I've read of 2 different ways. The official way seems to be running the wire under the foot bed (or in my case a custom orthotic), cutting a small incision in the boot liner heel and feed the wire up. I've also heard of feeding the wire through the toe of the liner, running the wire along the the top or side of the liner. When I asked this shop about the toe method he said no that's now how it's done and showed me the material on the front of the liner and saying something how it should not be cut. They also advised me the heating element would have to be moved back a bit since the orthotic was a bit narrow..
I'm a bit worried since the boot fitter I originally bought the boots and orthotic from I believe installs it through the toe. Their reasoning was if the wire ran under the orthotic it could cause it to slip or become unbalanced defeating the purpose of it. Although I've heard of some installs carving out a cable channel of some sort on the orthotic. What are your thoughts on this?
