Excellent points, esp. following the rules, simple packing list. I've thought of and discussed with other people the cost factor. What if it's something as simple as wearing a pair of thin, black Army dress socks, already issued and you can just continually flip them inside out as needed, it really does help eliminate an awful lot of friction blisters. Some guys even use panty hose (their wives, moms or whatever is covered under the don't ask don't tell policy
)
