And come up with a case for moccasins as the ultimate survival footwear.
Easy to learn to make. (Self-sufficiency) The materials should be widely available even post-collapse.
Used by the Indians prior to European Settlement (and even afterwards.)
Quiet.
Can be fur lined for warmth.
Recent research indicates that walking/running on your toes is healthier than heel to toe and a moccasin is likely to encourage such form, especially in comparison to boots.
Anyone else got something to add?
