Each of us, for our own individual reasons have blogs in our readers we have no business reading. One of mine is Godammit I'm Mad. I'll not explain why. Sister Wolf the blog's creator recently had a post on the Virtual Shoe Museum, the largest collection of (women's) tribal and ethnographic shoes in the world.
The extensive, easy to use database allows travelers to search for shoes by color, material,designer etc etc etc. Some, like those in the first photo are scary, some will make you scratch your head, many are beautiful.
Be certain to check out the bookstore.
