I don't wear heels often, but I do love them. I tend to spend my days in trainers because it's more practical, but I just bought a pair of boots with gorgeous two inch dolly heels, I have some gorgeous black leather pumps with a 2 1/2 inch heel, and I have a gorgeous pair of boots with a four inch stilleto wedge heel. I can walk just fine in all of them and they're all wonderfully comfortable :)
I find that 2 1/2 inches is a really comfortable height, and I'm really stable in them - which is good, because that's the height of the spanish heel on my dancing shoes!
