Okay, I'm very used to heels. I have friends at university with me who claim to never have seen me in flats -- my bunch and I have been together for a varying period up to a year and a half. But the highest pair I have is probably 3.5 inches, tops.

But I'm very fussy about shoes, and Duo boots are some of the most comfy I've ever bought.

Don't get a kitten heel. If you got the Penna, it is a kitten heel -- I have a pair myself. Square heels are better if you have foot issues.
