My posture is appalling since I stopped wearing high heels. I feel I really slump now and my chiropractor agrees! In an effort to improve said posture (and reduce consequential back pain) I have 2 pairs of suede boots with 1.5 to 2-inch wedge heels. I feel more elegant wearing them but can't walk too far or for too long in them (2-3 hours), but they do make me feel good!
Incidentally, I have 2 pairs of FitFl*ps sandals that are so comfortable I can wear them all day, yet a chiropodist recently told me they are not good for your feet. I was so shocked I didn't think to ask her why but she did agree that, as I found them sheer bliss to wear , I should continue.
