| Pat,
It could be one of may or even a couple of things. The first thing I would look at is the footbed, Is it posted firm enough. You must stop your foot from moving first. The blood flow is being shut down for a couple reasons, the padding has moved (very unlikely) or the liner is packed out. The boot is to big, and the c-pads that are in the liner don't line up to tour ankle. Or you could have a pressure that is tough to find.
