This is an old thread. But, I wish I had seen it earlier. I bought boots from Claude - full fitting, his recommended boots, custom footbeds - top to bottom his recommendation in March 2013. From day one, I said that I thought they were too big. He assured me they weren't. The first time I went back (after about 8 days) he added heel pads. The second time I went back (Feb 2014) he added material under the footbeds. In fairness to him, he offers a 12 month guarantee and due to a death in my family my season ended in the beginning of March. In December 2014, I still had the same problem - popping out of the heel cup. I went back in January. In his words - "this is the last thing we will be doing." He also said that my foot was the problem - overly mobile, which he had never mentioned previously. He insisted the boot was the right fit. He added yet more padding - heels and instep. I just returned from the most interesting week in Utah. I learned to ski my boot really loose because any buckle tightening put me into "through the roof" crying in the lodge type of pain. I also learned that by skiing really aggressively, I could ski myself back into the heel cup. However, I didn't risk skiing any serious stuff.
Oh ... I forgot the motto posted on the wall of Skinet Sports ... "If you don't love it, you don't own it." I went back 3 times because I didn't love it, but apparently ... I own it anyway. Everytime, I had the same complaint - heel and ankle was too loose.
$1000.00 wasted. I could have fit myself better online. Luckily, Kevin from Footloose just relocated to Encinitas,Ca. I trusted Claude, though, so now I'm skeptical of boot fitters period.
