Some basic topics that come up are:
1) Sizing. The great image posted with all of the lasts could be supplemented with user's experiences.
2) Break-in procedure
3) Caring for shell cordovan
4) Observations about the different types of soles (double leather, waterloc, crepe)
5) Variations on the Indy boot
6) Variations in color within the same shell color
Worthwhile? I could help compile stuff or if someone else wants to step up go for it (Namor? NYRanger?)
I know a lot of this is already scattered throughout the thread and on various websites but it would be nice to have it all in one place.
