Jo Ellen, I agree with you. I try to pick up anything that will be tempting. Sure, we take away things the puppy can't have. As he gets older, he will learn, this is your toy. This is not your toy. I don't think it is realistic to expect a pup to know he can't chew on the boot.
Spirit sounds like a very good boy. I have a new mix puppy, who sits on top of the trash can, stole a box of candy, DOES pull the table cloth off the table. Want to trade? LOL!
PS Tell your friend she best not be bringing any boots to my house - socks either.
