Hi Everyone, I have an odd problem that I haven't read about before. I have a pair of Tecnica Inferno Heats with custom insoles. My problem is when I'm skiing or even just standing my left heel is kind of suspended about 1/16 of an inch above insole. It wouldn't concern me except that I noticed when carving to the right, with the left leg downhill, I use the tails of the skis. Can I just cut off the heel of a boot shim and adhere it to the boot board to take up the space or could the problem caused by the insole?
