Assuming this is partly addressed to me, for my feet - Barrie is 0.5 down, Truebalance is 0.5 to 1.0 down, Grant and Tremont are TTS.
I do not own any Chukkas, so can't comment. LWB is NOT a full size down for me - its a Barrie lasted shoe, so I went the usual 0.5 down and it fits great, ymmv of course.
I wear 0.5 down in both a Barrie boot and shoe. I do have a Barrie CXL PCT boot that I bought TTS to wear specifically in the winter with heavy socks.
I also notice alot of guys here doing LWB's without socks. Are they using super low-cut socks or really no socks? Should that be another half size down?
Interesting, seems to maybe be a pattern with this boot then. I will contact J Crew. Was worried about the wait for a new pair if return was required, but I guess with summer finally arriving I can take them out of rotation for a while. Thanks for the advice, guys.
