I have several hammock socks - all diy kind. Yes, indeed the socks trap 10 to 15 degrees or more. Just don't make a sock from water proof material. It needs to be breathable to keep the condensation at bay. They're very easy to make and very light weight if you use 1.1 ripstop with a DWR coating or no coating at all.
