Update - 22 November - these may very well be brand new - I began disassembling them for Monday trash pick up - and found that they appear to be COMPLETELY UNUSED. I still have all the parts - and they only thing is that they were no longer in the original bags or wrappers, but I found no signs of use in either of the two boots.
Pair of large in good condition. If anyone knows of anywhere that wants these, let me know. They did not belong in the blue recycling can and I thought that there were organizations that would take them, but have not had much luck. Hate to just throw them in the regular landfill.
