Carry the socks with you and only apply them when your feet start to get a little cold.I had the same problems with old Sorels when I was kid (felt liners) and bought a pair of LaCrosse Ice Kings about 20 years ago. I haven't worn them in the last 5 or so. I havea pair of $189 Dannersthat were on a blowout sale at Scheel's(WI-ites will know) for $85. I carry in those big quilted over bootswhen I know it will get COLD and put the self-stick reactive toe warmers insideeach outer boot. Snug as a bug......

Here's the boots: http://www.cabelas.com/cabelas/en/templates/links/link.jsp?id=0006712810623a&type=product&cm Cat=search&returnPage=search-results1.jsp&QueryText=boot+covers&N=4887& amp;Ntk=Products&Ntx=mode+matchall&Nty=1&a mp;Ntt=boot+covers&noImage=0

They're not made for walking in, but they are extremely quiet in the treestand and worth every penny. Wait til late winter and start looking for some good sales on the winter boots. I see they are listed for $50...got mine for $35 at the end of winter 2 years ago.
