Thanks for your quick reply CEM. I have a fused right ankle and a huge calcium deposit on the inside of that ankle that lies right over the nerve. Had extensive boot work done a couple of years ago and they punched out the side over the calcium deposit but it's right where the hinge is, so it can't be stretched anymore. I placed some padding above the ankle and that seemed to help. I hate to toss the boots. My boot work cost me a small fortune. Had the soles planed 5 degrees out on that boot and 1.5 in on the left. They work great, they just kill my feet though! The cold feet might be from the circulation, but they really had to stretch the liner to get my size 8.5 feet into them.
Never heard that the lack of flexion could contribute to my cold feet, but now that you mention it...I can see that being one of the main causes for it.
Thanks again for the help.
