Nevertheless, I expect I may need to wear a 2nd pair of socks even after I re-insert the inserts while walking around camp.

  I hate to be a nay-sayer, but when you say "inserts", are you talking about the ones that have a heel cup and ARCH support molded in them?

IF so, you're robbing Peter to pay Paul foot wise.
You should ALWAYS bring the socks/booties you intend to wear IF possible when buying new footwear OR buy them big enough that you DON'T need to remove the inserts/arch supports.

  Having your arch supported under a heavy load is very important not just for your feet, but your ankles/knees and even lower back. Pain travels upward when you have bad arch support in your shoes.

  Sometimes it's hard to put those Neoprene booties in a shoe/boot because they SNAG that insert and it's a real pain. That's when many people take them out.

Since you already have the boot, try this little trick and see if it will work for you?

Put the INSERT inside the neoprene bootie with your regular sock choice and walk around a little bit to make sure the feel good, THEN see if you can get your shoe on? If so and you can lace them right, you can keep that important arch support.  ;) 8-)
