text: I used to complain when my sox slid down into my hip boots, etc.  My wife tired of my sometimes censorable comments, so she sewed some smoked moose skin up to make me a "half leather sock"  It worked!  No blisters, sox stayed in place & few holes in the heels of the sox.. After awhile she used split cowhide. We got them patented & call 'em "Jake's Achilles Heel Savers"  They don't cure all ills, but they sure take the bite & sting off many.
