wear long socks. the tops can be used for and to hold a dressing on a wound, the pill from the cotton can be used for tinder, you can put a weight in the toe for a weapon, can use to tie something (they're pretty tough) rip into strips and braid for cordage (sucks but better than nothing) can use your extra pair to pack things and cut down on rattles, sweat band, put under watch to absorb sweat/irritation, cut off the top for emergency t.p. use for a potholder/heat-shield (looks silly but its better than burning your arm on a hot exhaust) trail markers, bound tightly a wick or tinderbox (will smolder and stink all day).
