just don't over do it la. for casual walk around where people won't notice anything, try go for as minimal heel as possible.

yup. walking - get a proper shoe, minimal heels. one that's comfortable.

i think heels are necessary for appearance but if you spend most of the time in office, keep a pair of comfortable walking shoes to go around the office. some ladies do that, especially those working in Admin / HR where they don't go out and meet people like Sales & Marketing.
